TRAK Architecture Framework MetamodelOntology Description - Node Elements
Introduction
This page presents definitions of the individual TRAK metamodel node elements taken from the . TRAK Metamodel specification. The master source definition for any element is the TRAK Metamodel specification - this page is provided for information only. It presents some of the information that is contained in the underlying ontology description, again based on the TRAK metamodel.
The ontology description is an approximation of the TRAK metamodel owing to the limitations of the OWL / RDF(S) ontology description languages - for example by describing only individual elements not the triples formed from them.
An ontology is not a metamodel - the TRAK metamodel contains an ontology. It also contains a taxonomy. The TRAK metamodel is also not a taxonomy. The TRAK metamodel is defined by triples which are not an ontology nor a taxonomy. More details are provided separately.
- Ontology description: https://purl.org/trak/elements/#
The TRAK ontology description defines this as the base URI where the 'trak:' namespace = 'https://purl.org/trak/elements/#'
Metadata
List of node element ontology descriptions for the metamodel of the TRAK architecture framework. Note that this defines the meaning of isolated elements not triples and hence does not define the TRAK metamodel. See https://trakmetamodel.sourceforge.io/metamodel/ontology_vs_metamodel.html
- Specification: TRAK00002. TRAK. Architecture Framework. Metamodel.
- Release date: 2025-04-30
Characteristics
- Ontology c 2,200 statements / assertions / axioms
- Classes (nodes): 53
- Object properties (relationships): 79
- Transitive: 48
- Symmetrical: 4
- Data properties (properties): 120
- Individuals (property values): 101
Limitations
The development of the ontology description of the TRAK metamodel and the presentation of some of this in these HTML pages is an ongoing activity and is not complete. There will also likely be limitations owing to the capabilities that ontology description languages provide (and lack).
Limitations - HTML Presentation
- Properties. No linkage of properties to Nodes, Connectors. No enumerations (not described in RDF/XML ontology - see below).
Limitations - RDF/XML Ontology Description
- Enumerated lists - allowed / default values missing
- Metamodel tuples. No definition of the individuals (each triple) that comprise the TRAK metamodel.
