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 property representing a concept unique identifier within the NCI Enterprise Vocabulary Service's NCI Thesaurus.
A property that represents a description of the sort of thing or category to which a concept belongs in the context of the UMLS semantic network.
In general, applying semantic types aids in allowing users (or computer programs) to draw conclusions about concepts by virtue of the categories to which they have been assigned. We use a set of semantic types developed for the UMLS Metathesaurus. There are currently 134 semantic types in the UMLS.
A property representing an alternative Preferred Name for use in some NCI systems.
A property representing the word or phrase that NCI uses by preference to refer to the concept.
A property representing the concept unique identifier (CUI) assigned by the National Library of Medicine (NLM). If a concept in any NCI-maintained knowledgebase exists in the NLM Unified Medical Language System (UMLS), NCI includes the NLM CUI among the information we provide about the concept.
A property is used to indicate when a non-EVS entity has contributed to, and has a stake in, a concept. This is used where such entities, within or outside NCI, have indicated the need to be able to track their own concepts. A single concept can have multiple instances of this property if multiple entities have such a defined stake.
A property representing the English language definition of a concept from a source other than NCI.
A property representing a retired unique concept identifier created and stored as Concept Name by legacy EVS software. Use of these values was long discouraged, but continued as late as 2009 when creation of new values ceased and Concept Name was retired. Legacy values are intended solely to help resolve and update earlier coding.
A property representing notations made by NCI vocabulary curators. They are intended to provide supplemental, unstructured information to the user or additional insight about the concept.
A property representing a fully qualified synonym, contains the string, term type, source, and an optional source code if appropriate. Each subfield is deliniated to facilitate interpretation by software.
An association that connects the concept defining a particular terminology subset with concepts that belong to this subset.

p is a process = Def. p is an occurrent that has temporal proper parts and for some time t, p s-depends_on some material entity at t. (axiom label in BFO2 Reference: [083-003])
BFO 2 Reference: The realm of occurrents is less pervasively marked by the presence of natural units than is the case in the realm of independent continuants. Thus there is here no counterpart of ‘object’. In BFO 1.0 ‘process’ served as such a counterpart. In BFO 2.0 ‘process’ is, rather, the occurrent counterpart of ‘material entity’. Those natural – as contrasted with engineered, which here means: deliberately executed – units which do exist in the realm of occurrents are typically either parasitic on the existence of natural units on the continuant side, or they are fiat in nature. Thus we can count lives; we can count football games; we can count chemical reactions performed in experiments or in chemical manufacturing. We cannot count the processes taking place, for instance, in an episode of insect mating behavior.Even where natural units are identifiable, for example cycles in a cyclical process such as the beating of a heart or an organism’s sleep/wake cycle, the processes in question form a sequence with no discontinuities (temporal gaps) of the sort that we find for instance where billiard balls or zebrafish or planets are separated by clear spatial gaps. Lives of organisms are process units, but they too unfold in a continuous series from other, prior processes such as fertilization, and they unfold in turn in continuous series of post-life processes such as post-mortem decay. Clear examples of boundaries of processes are almost always of the fiat sort (midnight, a time of death as declared in an operating theater or on a death certificate, the initiation of a state of war)

An agency food product type is a class of food product defined by an agency or consortium.
Damion Dooley
This class is designed to hold 3rd party food classification schemes which are being mapped to FoodOn classes using the 'has member' relation. The two hierarchies are not melded into a subclass polyhierarchy because of possible logical inconsistencies in the agency schemes. The hierarchies of agency schemes are as true to their agency representation as possible.

PMID: 16353909.AAPS J. 2005 Sep 22;7(2):E274-80. Review. The joint food and agriculture organization of the United Nations/World Health Organization Expert Committee on Food Additives and its role in the evaluation of the safety of veterinary drug residues in foods.
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.

FeatureOfInterest
When measuring the height of a tree, the height is the observed ObservableProperty, 20m may be the Result of the Observation, and the tree is the FeatureOfInterest. A window is a FeatureOfInterest for an automatic window control Actuator.
The Result of an Observation, Actuation, or act of Sampling. To store an observation's simple result value one can use the hasSimpleResult property.
Result
The value 20 as the height of a certain tree together with the unit, e.g., Meter.
A Sample is the result from an act of Sampling.
Feature which is intended to be representative of a FeatureOfInterest on which Observations may be made.
Physical samples are sometimes known as 'specimens'.
Samples are artifacts of an observational strategy, and have no significant function outside of their role in the observation process. The characteristics of the samples themselves are of little interest, except perhaps to the manager of a sampling campaign. A Sample is intended to sample some FatureOfInterest, so there is an expectation of at least one isSampleOf property. However, in some cases the identity, and even the exact type, of the sampled feature may not be known when observations are made using the sampling features.
Sample
A 'station' is essentially an identifiable locality where a sensor system or Procedure may be deployed and an observation made. In the context of the observation model, it connotes the 'world in the vicinity of the station', so the observed properties relate to the physical medium at the station, and not to any physical artifact such as a mooring, buoy, benchmark, monument, well, etc.
A statistical sample is often designed to be characteristic of an entire population, so that observations can be made regarding the sample that provide a good estimate of the properties of the population.
A transient sample, such as a ships-track or flight-line, might be identified and described, but is unlikely to be revisited exactly.
Device, agent (including humans), or software (simulation) involved in, or implementing, a Procedure. Sensors respond to a stimulus, e.g., a change in the environment, or input data composed from the results of prior Observations, and generate a Result. Sensors can be hosted by Platforms.

Represents the measured value made over a property. It is also linked to the unit of measure in which the value is expressed and the timestamp of the measurement.
Measurement
The unit of measure is a standard for measurement of a quantity, such as a Property. For example, Power is a property and Watt is a unit of power that represents a definite predetermined power: when we say 10 Watt, we actually mean 10 times the definite predetermined power called "watt". Our definition is based on the definition of unit of measure in the Ontology of units of Measure (OM). We propose here a list of some units of measure that are relevant for the purpose of SAREF, but this list can be extended, also using some other ontologies rather than the Ontology of units of Measure (OM).
