TRAK Architecture Framework MetamodelVocabulary Description - Property Elements (Data Properties)
Introduction
This page presents definitions of the individual TRAK metamodel elements taken from the TRAK00002. 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 vocabulary description, again based on the TRAK metamodel.
The vocabulary 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.
The TRAK metamodel is defined by triples not individual elements. The TRAK metamodel is neither an ontology nor a taxonomy.
An ontology is not a metamodel. The TRAK metamodel contains a taxonomy. The TRAK metamodel is also not a taxonomy.
The meanings of each individual TRAK metamodel element form a vocabulary. The vocabulary of the TRAK metamodel elements is described using RDF/XML and Turtle. These vocabuary descriptions are not an ontology - in W3C terms they are 'ontology documents', NOT ontologies. More details are provided separately.
- Vocabulary description: https://purl.org/trak/metamodel/vocab#
The TRAK vocabulary description defines this as the base URI where the 'trak:' namespace = 'https://purl.org/trak/elements/#'
Metadata
List of property element vocabulary 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 Metamodel vs Ontology vs Taxonomy vs Vocabulary.

Characteristics
- Vocabulary description c 4,700 statements / assertions / axioms
- Classes (nodes): 53
- Object properties (relationships): 79
- Transitive: 48
- Symmetrical: 4
- Data properties (properties): 118
- Individuals (property values): 137
Formats
The vocabulary description of the TRAK metamodel is available in the following file formats:-
- this page - a simple HTML presentation with a separate web page for metamodel node, connector and property elements
- Resource Description Format (RDF):-
- a Turtle (Terse RDF Triple Language) file - trak_vocab.ttl.
- RDF/XML - a XML file - trak_vocab.rdf.
Standards
The vocabulary description is fully standards-compliant:-
- ‘OWL 2 Web Ontology Language Structural Specification and Functional-Style Syntax (Second Edition).’, World Wide Web Consortium (W3C), 11-Dec-2012.
- ‘RDF Schema 1.1’, World Wide Web Consortium (W3C), Feb. 2014.
- ‘RDF 1.1 Turtle’. World Wide Web Consortium (W3C), 25-Feb-2014.
- ‘RDF 1.1 Concepts and Abstract Syntax’, World Wide Web Consortium (W3C), Feb. 2014.
Limitations
The development of the vocabulary 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
- No page describing enumerations and enumerated values (to be done).
Limitations - Turtle and RDF/XML Vocabulary Descriptions
- Enumerated lists - default values missing. Description languages do not provide capability to define a default value. Expected default value added as comment to each DatatypeProperty (metamodel element property) that holds an enumerated value.
- Metamodel tuples. No definition of the individuals (each triple) that comprise the TRAK metamodel.
