PMD Core Ontology: Description back to ToC

The Platform MaterialDigital Core Ontology (PMDco) is a mid-level semantic framework for Materials Science and Engineering (MSE). Aligning with the ISO/IEC 21838-2:2021 standard, PMDco constructed on basis of Basic Formal Ontology (BFO) and reuses several BFO-aligned ontologies like RO, IAO, and OBI. The scope of PMDco follows the fundamental paradigm of MSE (processing, structure, and properties) and encompasses the following domains: (*) Processes: Representation of MSE-related process chains, including materials manufacturing, characterization, and simulation processes. (*) Structure/state: Description of substances, engineered materials, and specification of materials, their composition, and multiscale structural features. (*) Properties: Specification of material properties and qualities, representing processing-structure-properties dependences. PMDco also provides general entities required for representing the fundamental MSE topics (e.g., thermodynamics), as well as general semantics for entities commonly required across MSE disciplines (such as devices, roles, functions, and plans).

material performance propertyc back to ToC or Class ToC

IRI: https://w3id.org/pmd/co/PMD_0000005

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.

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.

Multiple specifically dependent continuants can concretize the same generically dependent continuant.
Example 
A journal article is an information artifact that inheres in some number of printed journals. For each copy of the printed journal there is some quality that carries the journal article, such as a pattern of ink. The quality (a specifically dependent continuant) concretizes the journal article (a generically dependent continuant), and both depend on that copy of the printed journal (an independent continuant).
An investigator reads a protocol and forms a plan to carry out an assay. The plan is a realizable entity (a specifically dependent continuant) that concretizes the protocol (a generically dependent continuant), and both depend on the investigator (an independent continuant).

IRI: http://purl.obolibrary.org/obo/RO_0000058

A relationship between a generically dependent continuant and a specifically dependent continuant or process, in which the generically dependent continuant depends on some independent continuant or process in virtue of the fact that the specifically dependent continuant or process also depends on that same independent continuant. A generically dependent continuant may be concretized as multiple specifically dependent continuants or processes.
Example 
A journal article is an information artifact that inheres in some number of printed journals. For each copy of the printed journal there is some quality that carries the journal article, such as a pattern of ink. The journal article (a generically dependent continuant) is concretized as the quality (a specifically dependent continuant), and both depend on that copy of the printed journal (an independent continuant).
An investigator reads a protocol and forms a plan to carry out an assay. The plan is a realizable entity (a specifically dependent continuant) that concretizes the protocol (a generically dependent continuant), and both depend on the investigator (an independent continuant). The plan is then realized by the assay (a process).

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.
