Dies ist die PMD-Ontologie für Zugversuche (Tensile Test Ontology – TTO), die auf der Grundlage der Prüfnorm "ISO 6892-1: Metallische Werkstoffe – Zugversuche – Teil 1: Prüfverfahren bei Raumtemperatur" entwickelt wurde. Die TTO wurde im Rahmen des PMD-Projekts entwickelt. Die TTO bietet Konzeptualisierungen, die für die Beschreibung von Zugversuchen und entsprechenden Daten gemäß der jeweiligen Prüfnorm gültig sind. Durch die Verwendung der TTO zur Speicherung von Zugversuchsdaten sind alle Daten gut strukturiert und basieren auf einem gemeinsamen Vokabular, das von einer Expertengruppe vereinbart wurde (Erzeugung von FAIRen-Daten), was zu einer verbesserten Dateninteroperabilität führen wird. Durch den Import der PMD Core Ontology (PMDco) wird die Interoperabilität von Zugprüfungsdaten verbessert und die Abfrage in Kombination mit anderen Aspekten und Daten aus dem breiten Feld der Materialwissenschaft und Werkstofftechnik (MSE) erleichtert.
This is thePMD ontology of the tensile test (Tensile Test Ontology - TTO) as developed on the basis of the test standard ISO 6892-1: Metallic materials - Tensile Testing - Part 1: Method of test at room temperature. The TTO was developed in the frame of the PMD project. The TTO provides conceptualizations valid for the description of tensile tests and corresponding data in accordance with the respective test standard. By using TTO for storing tensile test data, all data will be well structured and based on a common vocabulary agreed on by an expert group (generation of FAIR data) which will lead to enhanced data interoperability. Due to the import of the PMD core ontology (PMDco), the interoperability of tensile test data is enhanced and querying in combination with other aspects and data within the broad field of material science and engineering (MSE) is facilitated.

2012-04-05: Barry Smith The official OBI definition, explaining the meaning of a class or property: 'Shall be Aristotelian, formalized and normalized. Can be augmented with colloquial definitions' is terrible. Can you fix to something like: A statement of necessary and sufficient conditions explaining the meaning of an expression referring to a class or property. Alan Ruttenberg Your proposed definition is a reasonable candidate, except that it is very common that necessary and sufficient conditions are not given. Mostly they are necessary, occasionally they are necessary and sufficient or just sufficient. Often they use terms that are not themselves defined and so they effectively can't be evaluated by those criteria. On the specifics of the proposed definition: We don't have definitions of 'meaning' or 'expression' or 'property'. For 'reference' in the intended sense I think we use the term 'denotation'. For 'expression', I think we you mean symbol, or identifier. For 'meaning' it differs for class and property. For class we want documentation that let's the intended reader determine whether an entity is instance of the class, or not. For property we want documentation that let's the intended reader determine, given a pair of potential relata, whether the assertion that the relation holds is true. The 'intended reader' part suggests that we also specify who, we expect, would be able to understand the definition, and also generalizes over human and computer reader to include textual and logical definition. Personally, I am more comfortable weakening definition to documentation, with instructions as to what is desirable. We also have the outstanding issue of how to aim different definitions to different audiences. A clinical audience reading chebi wants a different sort of definition documentation/definition from a chemistry trained audience, and similarly there is a need for a definition that is adequate for an ontologist to work with.

a core relation that holds between a part and its whole
Everything is part of itself. Any part of any part of a thing is itself part of that thing. Two distinct things cannot be part of each other.
Occurrents are not subject to change and so parthood between occurrents holds for all the times that the part exists. Many continuants are subject to change, so parthood between continuants will only hold at certain times, but this is difficult to specify in OWL. See http://purl.obolibrary.org/obo/ro/docs/temporal-semantics/
Parthood requires the part and the whole to have compatible classes: only an occurrent can be part of an occurrent; only a process can be part of a process; only a continuant can be part of a continuant; only an independent continuant can be part of an independent continuant; only an immaterial entity can be part of an immaterial entity; only a specifically dependent continuant can be part of a specifically dependent continuant; only a generically dependent continuant can be part of a generically dependent continuant. (This list is not exhaustive.) A continuant cannot be part of an occurrent: use 'participates in'. An occurrent cannot be part of a continuant: use 'has participant'. A material entity cannot be part of an immaterial entity: use 'has location'. A specifically dependent continuant cannot be part of an independent continuant: use 'inheres in'. An independent continuant cannot be part of a specifically dependent continuant: use 'bearer of'.

This document is about information artifacts and their representations
A (currently) primitive relation that relates an information artifact to an entity.
7/6/2009 Alan Ruttenberg. Following discussion with Jonathan Rees, and introduction of "mentions" relation. Weaken the is_about relationship to be primitive. We will try to build it back up by elaborating the various subproperties that are more precisely defined. Some currently missing phenomena that should be considered "about" are predications - "The only person who knows the answer is sitting beside me" , Allegory, Satire, and other literary forms that can be topical without explicitly mentioning the topic.
Smith, Ceusters, Ruttenberg, 2000 years of philosophy

A person's name denotes the person. A variable name in a computer program denotes some piece of memory. Lexically equivalent strings can denote different things, for instance "Alan" can denote different people. In each case of use, there is a case of the denotation relation obtaining, between "Alan" and the person that is being named.
A primitive, instance-level, relation obtaining between an information content entity and some portion of reality. Denotation is what happens when someone creates an information content entity E in order to specifically refer to something. The only relation between E and the thing is that E can be used to 'pick out' the thing. This relation connects those two together. Freedictionary.com sense 3: To signify directly; refer to specifically
2009-11-10 Alan Ruttenberg. Old definition said the following to emphasize the generic nature of this relation. We no longer have 'specifically denotes', which would have been primitive, so make this relation primitive. g denotes r =def r is a portion of reality there is some c that is a concretization of g every c that is a concretization of g specifically denotes r

denotes
m is a quality measurement of q at t. When q is a quality, there is a measurement process p that has specified output m, a measurement datum, that is about q
8/6/2009 Alan Ruttenberg: The strategy is to be rather specific with this relationship. There are other kinds of measurements that are not of qualities, such as those that measure time. We will add these as separate properties for the moment and see about generalizing later
From the second IAO workshop [Alan Ruttenberg 8/6/2009: not completely current, though bringing in comparison is probably important] This one is the one we are struggling with at the moment. The issue is what a measurement measures. On the one hand saying that it measures the quality would include it "measuring" the bearer = referring to the bearer in the measurement. However this makes comparisons of two different things not possible. On the other hand not having it inhere in the bearer, on the face of it, breaks the audit trail. Werner suggests a solution based on "Magnitudes" a proposal for which we are awaiting details. -- From the second IAO workshop, various comments, [commented on by Alan Ruttenberg 8/6/2009] unit of measure is a quality, e.g. the length of a ruler. [We decided to hedge on what units of measure are, instead talking about measurement unit labels, which are the information content entities that are about whatever measurement units are. For IAO we need that information entity in any case. See the term measurement unit label] [Some struggling with the various subflavors of is_about. We subsequently removed the relation represents, and describes until and only when we have a better theory] a represents b means either a denotes b or a describes describe: a describes b means a is about b and a allows an inference of at least one quality of b We have had a long discussion about denotes versus describes.
From the second IAO workshop: An attempt at tieing the quality to the measurement datum more carefully. a is a magnitude means a is a determinate quality particular inhering in some bearer b existing at a time t that can be represented/denoted by an information content entity e that has parts denoting a unit of measure, a number, and b. The unit of measure is an instance of the determinable quality.
From the second meeting on IAO: An attempt at defining assay using Barry's "reliability" wording assay: process and has_input some material entity and has_output some information content entity and which is such that instances of this process type reliably generate outputs that describes the input.

this fragility is a characteristic of this vase
this red color is a characteristic of this apple
a relation between a specifically dependent continuant (the characteristic) and any other entity (the bearer), in which the characteristic depends on the bearer for its existence.
Note that this relation was previously called "inheres in", but was changed to be called "characteristic of" because BFO2 uses "inheres in" in a more restricted fashion. This relation differs from BFO2:inheres_in in two respects: (1) it does not impose a range constraint, and thus it allows qualities of processes, as well as of information entities, whereas BFO2 restricts inheres_in to only apply to independent continuants (2) it is declared functional, i.e. something can only be a characteristic of one thing.

location of
my brain is located in my head
this rat is located in this cage
a relation between two independent continuants, the target and the location, in which the target is entirely within the location
Location as a relation between instances: The primitive instance-level relation c located_in r at t reflects the fact that each continuant is at any given time associated with exactly one spatial region, namely its exact location. Following we can use this relation to define a further instance-level location relation - not between a continuant and the region which it exactly occupies, but rather between one continuant and another. c is located in c1, in this sense, whenever the spatial region occupied by c is part_of the spatial region occupied by c1. Note that this relation comprehends both the relation of exact location between one continuant and another which obtains when r and r1 are identical (for example, when a portion of fluid exactly fills a cavity), as well as those sorts of inexact location relations which obtain, for example, between brain and head or between ovum and uterus

Despite has characteristic from RO does not have any domain constraints, it is still not possible to directly connect an instance of a process with an instance of a SDC. First, SDC is dependent on a IC. As RO does not have "bearer of" object property, the "has characteristic" implies that the domain should be an IC. Second, characteristic of is a functional property. Thus, two triples SDC_1 characteristc of IC_1 and SDC_2 characteristc of Process_1 (where IC_1 participates in Process_1), cannot exist simultaneously. An example of such case can be "Temperature of during the annealing process was 1000°C". Temperature is an SDC of some participant of the annealing, however it is not clear whether it is an SDC of an oven or of a sample in the oven. If we assert triple Annealing--> has characteristic --> Temperature 1000°C, then the correct triple connecting temperature SDC with either oven or specimen cannot exist.

has relational quality
a relation between an independent continuant (the bearer) and a relational quality, in which the quality specifically depends on the bearer for its existence
material has relational quality mass proportion m, and portion of iron has the same relational quality mass proportion m
The 'relational quality of' is more strict that 'quality of' from RO, since domain is 'relational quality'. The motivtion to introduce an object property for relational qualities is the following: RO's 'quality of' is functional i.e., a->b, a->c => b=c. The functionality is relevant for most of the SDC -> IC triples, expect for relational qualities, which per definiton can be simultaneously inherited in >=2 ICs. Thus, 'relational quality of' has the same intention to connect SDC to IC, however, without cardinality constraints.
relational quality of
a relation between a relational quality and an independent continuant (the bearer), in which the quality specifically depends on the bearer for its existence
mass proportion m is relational qualitiy of material, and the same mass proportion m is relational qualitiy of portion of iron

BFO 2 Reference: One major family of examples of non-rigid universals involves roles, and ontologies developed for corresponding administrative purposes may consist entirely of representatives of entities of this sort. Thus ‘professor’, defined as follows,b instance_of professor at t =Def. there is some c, c instance_of professor role & c inheres_in b at t.denotes a non-rigid universal and so also do ‘nurse’, ‘student’, ‘colonel’, ‘taxpayer’, and so forth. (These terms are all, in the jargon of philosophy, phase sortals.) By using role terms in definitions, we can create a BFO conformant treatment of such entities drawing on the fact that, while an instance of professor may be simultaneously an instance of trade union member, no instance of the type professor role is also (at any time) an instance of the type trade union member role (any more than any instance of the type color is at any time an instance of the type length).If an ontology of employment positions should be defined in terms of roles following the above pattern, this enables the ontology to do justice to the fact that individuals instantiate the corresponding universals – professor, sergeant, nurse – only during certain phases in their lives.

Examples of measurement unit labels are liters, inches, weight per volume.
A measurement unit label is as a label that is part of a scalar measurement datum and denotes a unit of measure.
2009-03-16: provenance: a term measurement unit was proposed for OBI (OBI_0000176) , edited by Chris Stoeckert and Cristian Cocos, and subsequently moved to IAO where the objective for which the original term was defined was satisfied with the definition of this, different, term.
2009-03-16: review of this term done during during the OBI workshop winter 2009 and the current definition was considered acceptable for use in OBI. If there is a need to modify this definition please notify OBI.

In the protocol of a ChIP assay the objective specification says to identify protein and DNA interaction.
A directive information entity that describes an intended process endpoint. When part of a plan specification the concretization is realized in a planned process in which the bearer tries to effect the world so that the process endpoint is achieved.
2009-03-16: original definition when imported from OBI read: "objective is an non realizable information entity which can serve as that proper part of a plan towards which the realization of the plan is directed."
2014-03-31: In the example of usage ("In the protocol of a ChIP assay the objective specification says to identify protein and DNA interaction") there is a protocol which is the ChIP assay protocol. In addition to being concretized on paper, the protocol can be concretized as a realizable entity, such as a plan that inheres in a person. The objective specification is the part that says that some protein and DNA interactions are identified. This is a specification of a process endpoint: the boundary in the process before which they are not identified and after which they are. During the realization of the plan, the goal is to get to the point of having the interactions, and participants in the realization of the plan try to do that.

Data items include counts of things, analyte concentrations, and statistical summaries.
An information content entity that is intended to be a truthful statement about something (modulo, e.g., measurement precision or other systematic errors) and is constructed/acquired by a method which reliably tends to produce (approximately) truthful statements.
2/2/2009 Alan and Bjoern discussing FACS run output data. This is a data item because it is about the cell population. Each element records an event and is typically further composed a set of measurment data items that record the fluorescent intensity stimulated by one of the lasers.
2009-03-16: data item deliberatly ambiguous: we merged data set and datum to be one entity, not knowing how to define singular versus plural. So data item is more general than datum.
2009-03-16: removed datum as alternative term as datum specifically refers to singular form, and is thus not an exact synonym.

An information content entity is an entity that is generically dependent on some artifact and stands in relation of aboutness to some entity.
2014-03-10: The use of "thing" is intended to be general enough to include universals and configurations (see https://groups.google.com/d/msg/information-ontology/GBxvYZCk1oc/-L6B5fSBBTQJ).

information content entity
An information content entity whose concretizations indicate to their bearer how to realize them in a process.
2009-03-16: provenance: a term realizable information entity was proposed for OBI (OBI_0000337) , edited by the PlanAndPlannedProcess branch. Original definition was "is the specification of a process that can be concretized and realized by an actor" with alternative term "instruction".It has been subsequently moved to IAO where the objective for which the original term was defined was satisfied with the definitionof this, different, term.
2013-05-30 Alan Ruttenberg: What differentiates a directive information entity from an information concretization is that it can have concretizations that are either qualities or realizable entities. The concretizations that are realizable entities are created when an individual chooses to take up the direction, i.e. has the intention to (try to) realize it.
8/6/2009 Alan Ruttenberg: Changed label from "information entity about a realizable" after discussions at ICBO
Werner pushed back on calling it realizable information entity as it isn't realizable. However this name isn't right either. An example would be a recipe. The realizable entity would be a plan, but the information entity isn't about the plan, it, once concretized, *is* the plan. -Alan

Intensity values in a CEL file or from multiple CEL files comprise a data set (as opposed to the CEL files themselves).
A data item that is an aggregate of other data items of the same type that have something in common. Averages and distributions can be determined for data sets.
2009/10/23 Alan Ruttenberg. The intention is that this term represent collections of like data. So this isn't for, e.g. the whole contents of a cel file, which includes parameters, metadata etc. This is more like java arrays of a certain rather specific type
2014-05-05: Data sets are aggregates and thus must include two or more data items. We have chosen not to add logical axioms to make this restriction.

A directive information entity with action specifications and objective specifications as parts, and that may be concretized as a realizable entity that, if realized, is realized in a process in which the bearer tries to achieve the objectives by taking the actions specified.
2009-03-16: provenance: a term a plan was proposed for OBI (OBI_0000344) , edited by the PlanAndPlannedProcess branch. Original definition was " a plan is a specification of a process that is realized by an actor to achieve the objective specified as part of the plan". It has been subsequently moved to IAO where the objective for which the original term was defined was satisfied with the definitionof this, different, term.
2014-03-31: A plan specification can have other parts, such as conditional specifications.
2022-01-16 Updated definition to that proposed by Clint Dowloand, IAO Issue 231.
Alternative previous definition: a plan is a set of instructions that specify how an objective should be achieved
2/3/2009 Comment from OBI review. Action specification not well enough specified. Conditional specification not well enough specified. Question whether all plan specifications have objective specifications. Request that IAO either clarify these or change definitions not to use them

Words, sentences, paragraphs, and the written (non-figure) parts of publications are all textual entities
A textual entity is a part of a manifestation (FRBR sense), a generically dependent continuant whose concretizations are patterns of glyphs intended to be interpreted as words, formulas, etc.
AR, (IAO call 2009-09-01): a document as a whole is not typically a textual entity, because it has pictures in it - rather there are parts of it that are textual entities. Examples: The title, paragraph 2 sentence 7, etc.
MC, 2009-09-14 (following IAO call 2009-09-01): textual entities live at the FRBR (http://en.wikipedia.org/wiki/Functional_Requirements_for_Bibliographic_Records) manifestation level. Everything is significant: line break, pdf and html versions of same document are different textual entities.

Injecting mice with a vaccine in order to test its efficacy
A process that realizes a plan which is the concretization of a plan specification.
'Plan' includes a future direction sense. That can be problematic if plans are changed during their execution. There are however implicit contingencies for protocols that an agent has in his mind that can be considered part of the plan, even if the agent didn't have them in mind before. Therefore, a planned process can diverge from what the agent would have said the plan was before executing it, by adjusting to problems encountered during execution (e.g. choosing another reagent with equivalent properties, if the originally planned one has run out.)
PMDco : migration: https://github.com/materialdigital/core-ontology/issues/269
We are only considering successfully completed planned processes. A plan may be modified, and details added during execution. For a given planned process, the associated realized plan specification is the one encompassing all changes made during execution. This means that all processes in which an agent acts towards achieving some objectives is a planned process.

When a specimen of blood is assayed for glucose concentration, the blood has the evaluant role. When measuring the mass of a mouse, the evaluant is the mouse. When measuring the time of DNA replication, the evaluant is the DNA. When measuring the intensity of light on a surface, the evaluant is the light source.
a role that inheres in a material entity that is realized in an assay in which data is generated about the bearer of the evaluant role
Role call - 17nov-08: JF and MC think an evaluant role is always specified input of a process. Even in the case where we have an assay taking blood as evaluant and outputting blood, the blood is not the specified output at the end of the assay (the concentration of glucose in the blood is)

An entity that can bear roles, has members, and has a set of organization rules. Members of organizations are either organizations themselves or individual people. Members can bear specific organization member roles that are determined in the organization rules. The organization rules also determine how decisions are made on behalf of the organization by the organization members.
BP: The definition summarizes long email discussions on the OBI developer, roles, biomaterial and denrie branches. It leaves open if an organization is a material entity or a dependent continuant, as no consensus was reached on that. The current placement as material is therefore temporary, in order to move forward with development. Here is the entire email summary, on which the definition is based: 1) there are organization_member_roles (president, treasurer, branch editor), with individual persons as bearers 2) there are organization_roles (employer, owner, vendor, patent holder) 3) an organization has a charter / rules / bylaws, which specify what roles there are, how they should be realized, and how to modify the charter/rules/bylaws themselves. It is debatable what the organization itself is (some kind of dependent continuant or an aggregate of people). This also determines who/what the bearer of organization_roles' are. My personal favorite is still to define organization as a kind of 'legal entity', but thinking it through leads to all kinds of questions that are clearly outside the scope of OBI. Interestingly enough, it does not seem to matter much where we place organization itself, as long as we can subclass it (University, Corporation, Government Agency, Hospital), instantiate it (Affymetrix, NCBI, NIH, ISO, W3C, University of Oklahoma), and have it play roles. This leads to my proposal: We define organization through the statements 1 - 3 above, but without an 'is a' statement for now. We can leave it in its current place in the is_a hierarchy (material entity) or move it up to 'continuant'. We leave further clarifications to BFO, and close this issue for now.
organization
The plan of researcher X to perform an experiment according to a protocol.
A plan is a realizable entity that is the inheres in a bearer who is committed to realizing it as a completely executed planned process.
This class is included to make clear how the plan specification, the plan, and the planned process relate. OBI will however only subclass and work under the 'plan specification', and 'planned process' class, as we want to avoid to get deep into discussions of 'intend' etc.

The value of 'positive' in a classification scheme of "positive or negative"; the value of '20g' on the quantitative scale of mass.
An information content entity that specifies a value within a classification scheme or on a quantitative scale.
This term is currently a descendant of 'information content entity', which requires that it 'is about' something. A value specification of '20g' for a measurement data item of the mass of a particular mouse 'is about' the mass of that mouse. However there are cases where a value specification is not clearly about any particular. In the future we may change 'value specification' to remove the 'is about' requirement.

Instances of Portions Of Matter whose shape is relevant for their dispostion to participate in a manufacturing process may be (subclasses of) objects that bear a 'blank role' in the context of the manufacturing process.
Material is defined in terms of the three main perspectives that material specifications rely on: the structure of the material ("intensive quality"), the performance of the material ("behavoiral material property") and the processing the material must have undergone ("output of some process"). When defining specific materials/material taxonomies, these three aspects shall be taken into account in the aristotelian ("per genus et differentiam") as differentiation.
The sum of portions of matter of the same type form a portion of matter of that type.
Material

Portion of Material
A material is a portion of matter that may participate in some manufacturing process and whose shape is not relevant for its participation in the manufacturing process.
It is also representing a distinct physical or conceptual part of a material or substance. The open energy ontology OEO defines portion of matter as a subclass of object aggregate, which implies countability. Our portion is not (precisely) countable and thus bearer of intensive properties.
Lome explanation for portion of matter: "What is a molecule cluster at the cellular level? Contrary to the molecular level, at the cellular level of granularity the boundary of each molecule is outside of the level of granular focus. What forms a discontinuous cluster of countable individual molecules and thus bona fide objects at the molecular level, is a continuous and non-countable molecular substance at coarser levels of granularity. At these coarser levels, the individual molecules cannot be differentiated and demarcated anymore and the cluster as a whole possesses only fiat inner boundaries."
portion of matter
A material entity that is not demarcated by any physical discontinuities. At some finer level of granularity it is an object aggregate, at some coarser level of granularity it is a fiat object part,but at this level of granularity it is neither.
We recognize that some of the materials in the subclasses also occur naturally. However, these are not within the scope of our consideration for technical use.
engineered material
An engineered material is a material that is output of a manufacturing process.
A property is a material trait in terms of the kind and magnitude of response to a specific imposed stimulus. Generally, definitions of properties are made independent of material shape and size. (Callister, W.D., Rethwisch, D.G., Materials Science and Engineering, Wiley, 2014) Technical materials are complex aggregates. Many properties that are determined for those aggregates are intrinsically associated with the methodologies employed in the measurement process. This is in contrast to typical 'physical' properties, which like e.g. mass that can be determined to high accuracy independently of the measurement process. As a consequence, material properties in the ontology are differeciated according to their measurement method, e.g. Brinell hardness and Vickers hardness are different types of indentation hardness rather than different measures/quantification (GDC) of the materials property 'indentation hardness'. The 'unit idenifieres' of such properties (e.g. "HV1", "HV10", "HBW") are strictly speaking not units but rather references to the measurement methodology used to determine a numeric value that quantifies the property. Extensive properties that depend on the object being tested rather than on the portion of matter are (extensive) object- or system-properties.
material property
a disposition of a portion of matter that is realized in a compatible process and whose realization is grounded in the portions intensive qualities
Due to the duality of object and portion of matter this axiom can not be an equivalent class axiom.

vector field specification
Vector field specification is a value specification that represents an assignment of a vector to each point in a discretized spatial region.

Furthermore, process attribute describes how SDCs of some participants, i.e., ICs, change in a process. Specific rates, e.g., tensile rate, cooling rate, etc. should be added as subclasses of this class.

As "has quality" is an inverse functional property, only one instance of portion of matter can have this specific composition. However, proportions describe the relation between the prortion of matter (the whole) and some compound (the part). Thus, the following triples hold: portion of matter has relational quality proportion; portion of matter has part some substance (or whatever is your part); substance has relational quality proportion. "Has relational quality" is not inverse functional, i.e., it can point to a single object from 2 distinct subjects.

Dieses Konzept beschreibt die kleinste Querschnittsfläche des Zugprüfkörers, die nach dem Bruch infolge der aufgebrachten Zugkraft erhalten wird. Anmerkung: Sie wird in der Regel senkrecht zur Richtung der aufgebrachten Kraft gemessen und dient zur Berechnung der technischen Spannung während der Prüfung. Anmerkung: Es wird empfohlen, den Anfangsquerschnitt innerhalb der parallelen Länge mit einer Genauigkeit von ±2 % zu messen. Bei runden Prüfkörpern mit kleinem Durchmesser oder Prüfkörpern mit anderen Querschnittsgeometrien ist es jedoch möglicherweise nicht möglich, den Anfangsquerschnitt innerhalb der parallelen Länge mit einer Genauigkeit von ±2 % zu messen.
This concept describes the smallest cross-sectional area of the tensile test piece observed after it has fractured under the applied tensile force. Note: It is typically measured perpendicular to the direction of the applied force and is used to calculate engineering stress during the test.

example to be eventually removed
The term was used in an attempt to structure part of the ontology but in retrospect failed to do a good job
failed exploratory term
Class has all its metadata, but is either not guaranteed to be in its final location in the asserted IS_A hierarchy or refers to another class that is not complete.
metadata complete
Term created to ease viewing/sort terms for development purpose, and will not be included in a release
organizational term
Class has undergone final review, is ready for use, and will be included in the next release. Any class lacking "ready_for_release" should be considered likely to change place in hierarchy, have its definition refined, or be obsoleted in the next release. Those classes deemed "ready_for_release" will also derived from a chain of ancestor classes that are also "ready_for_release."
ready for release
Class is being worked on; however, the metadata (including definition) are not complete or sufficiently clear to the branch editors.
metadata incomplete
Nothing done yet beyond assigning a unique class ID and proposing a preferred term.
uncurated
All definitions, placement in the asserted IS_A hierarchy and required minimal metadata are complete. The class is awaiting a final review by someone other than the term editor.
pending final vetting
placeholder removed
An editor note should explain what were the merged terms and the reason for the merge.
terms merged
This is to be used when the original term has been replaced by a term imported from an other ontology. An editor note should indicate what is the URI of the new term to use.
term imported
This is to be used when a term has been split in two or more new terms. An editor note should indicate the reason for the split and indicate the URIs of the new terms created.
term split
Hard to give a definition for. Intuitively a "natural kind" rather than a collection of any old things, which a class is able to be, formally. At the meta level, universals are defined as positives, are disjoint with their siblings, have single asserted parents.
A Formal Theory of Substances, Qualities, and Universals, http://ontology.buffalo.edu/bfo/SQU.pdf
universal
A defined class is a class that is defined by a set of logically necessary and sufficient conditions but is not a universal
"definitions", in some readings, always are given by necessary and sufficient conditions. So one must be careful (and this is difficult sometimes) to distinguish between defined classes and universal.
defined class
A named class expression is a logical expression that is given a name. The name can be used in place of the expression.
named class expressions are used in order to have more concise logical definition but their extensions may not be interesting classes on their own. In languages such as OWL, with no provisions for macros, these show up as actuall classes. Tools may with to not show them as such, and to replace uses of the macros with their expansions
named class expression
Terms with this status should eventually replaced with a term from another ontology.
to be replaced with external ontology term
A term that is metadata complete, has been reviewed, and problems have been identified that require discussion before release. Such a term requires editor note(s) to identify the outstanding issues.
requires discussion
The term was added to the ontology on the assumption it was in scope, but it turned out later that it was not.
This obsolesence reason should be used conservatively. Typical valid examples are: un-necessary grouping classes in disease ontologies, a phenotype term added on the assumption it was a disease.
