Ontology in support of additive manufacturing for maintenance operations developed as part of the America Makes Additive With Knowledge project by SimbaChain and the Notre Dame Center for Research Computing, Laboratory for Assured AI Applications Development (LA3D).
The AMMO Ontology has been support the use of additive manufacturing for the production of parts in maintenance operations. Contributions and Discussion Welcomed. Ontology Versions 0.0.1 to 0.5.0 Funded by United States Army, America Makes Ontology Versions 0.5.0 to 0.6.0 Funded by United States Air Force, America Makes Changelog: 0.5.0: First Development Release. Extracted mereology and core patterns from Semantic Science Integrated Ontology (SIO). Implimented Material Transformation Pattern as a Processs. Defined lightweight vocabulary for Additive Manufacturing Processes as Material Transformations. 0.5.1: Changed documentation genration from Pylode to Widoco. Minor typo fixes. 0.6.0: Changed to direct import of SIO ontology to improve integration with Wikidata and NIST Material Genome Project. Removal of duplicate classes extracted from SIO as part of 0.5.0 release. Addition and refinement of Material Processing techniques derived from Material Genome Project Nanomine.

Additive Manufacturing Process
3D Printing Process
There is some cleanup in wikidata, Q360931 is subclass of manufacturing process, Q30592743 is subclass of production process
mixture or metallic solid solution composed of two or more elements
A material from which other materials are derived
Wikidata has the wrong subclass of additive manufacturing vs additive manufacturing process
a person or thing that causes a change
material made from a combination of two or more unlike substances
A collection of data, published or curated by a single agent, and available for access or download in one or more representations.
A design specification is a detailed document that sets out exaclty what a product or a process should present.
Hook for vocabulary that describes the specification entity
Design Specification Type
A PhysicalArtifact that is also described by a Design. This excludes simple recycling or refunctionalization of natural objects. Most common sense 'artifacts' can be included in this class: cars, lamps, houses, chips, etc.
Designed Artifact is extracted from DOLCE Ultra Lite Systems Lite
Digital Light Processing
DLP (Digital Light Processing) is a 3D printing technology used to rapidly produce photopolymer parts. It’s very similar to SLA with one significant difference -- where SLA machines use a laser that traces a layer, a DLP machine uses a projected light source to cure the entire layer at once. The part is formed layer by layer.
Wikidata has a misdirection to Digital Light Processing Display not a printing process
Substance that can occur in different amounts, all with some similar [mixture of some] characteristics, and of which objects can be made up
Material
Material Artifact
Any MaterialObject that isDescribedBy a Plan . This axiomatization is weak, but allows to talk of artifacts in a very general sense, i.e. including recycled objects, objects with an intentional functional change, natural objects that are given a certain function, even though they are not modified or structurally designed, etc. PhysicalArtifact(s) are not considered disjoint from PhysicalBody(s), in order to allow a dual classification when needed. E.g., FunctionalSubstance(s) are included here as well. Immaterial (non-physical) artifacts (e.g. texts, ideas, cultural movements, corporations, communities, etc. can be modelled as social objects (see SocialObject), which are all 'artifactual' in the weak sense assumed here.
From DUL: A Description of the Situation, in terms of structure and function, held by an Entity for some reason. A design is usually accompanied by the rationales behind the construction of the designed Entity (i.e. of the reasons why a design is claimed to be as such). For example, the actual design (a Situation) of a car or of a law is based on both the specification (a Description) of the structure, and the rationales used to construct cars or laws. While designs typically describe entities to be constructed, they can also be used to describe 'refunctionalized' entities, or to hypothesize unknown functions. For example, a cradle can be refunctionalized as a flowerpot based on a certain home design.
A design is a plan or specification for the construction of an object or system or for the implementation of an activity or process or the result of that plan or specification in the form of a prototype, product, or process.
A material transformation is a process that transforms material objects another.
Physical System
A physical object that isDescribedBy a SystemDesign . I.e., analytically: a 'natural' system whose constituents or parts are physical objects that are members of a Collection that isUnifiedBy a SystemDesign . Notice that such SystemDesign is not necessarily bound to a SystemImplementationWorkflow, therefore it can be a reconstruction (or theory) about the structure and functions of a natural system.
A Description having an explicit Goal, to be achieved by executing the plan
Plan
substance composed of macromolecules with repeating structural units
Quantity ODP is derived directly from QUDT and equivalent.
The description of a system from the design viewpoint: how it is structured, and the functions (tasks) that it should support. This may also include aesthetic functions and refunctionalizations.
