Vocabulary Description - Node Elements (Classes)

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 vocabuary description defines this as the base URI where the 'trak:' namespace = 'https://purl.org/trak/elements/#'

Metadata

List of node 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.

Specification: TRAK00002. TRAK. Architecture Framework. Metamodel.
Release date: 2025-12-17

Characteristics

Vocabulary description c 4,700 statements / assertions / axioms
Classes (nodes): 53
Object properties (relationships): 79
- Transitive: 48
- Symmetrical: 4
Data properties (properties): 120

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.

Comment: A Vision (Statement) outlines what the organisation wants to be. It concentrates on the future. It is a source of inspiration. It provides clear decision- making criteria. [Wikipedia]. A Mission Statement tells you the fundamental purpose of the organisation. It concentrates on the present. In TRAK therefore if an Enterprise is defined as having both the start and finish dates as [Today] and an Enterprise Goal is attached this is the equivalent to a Mission Statement.

Base URI: trak: = https://purl.org/trak/metamodel/vocab#

Label: 'System'

Definition: A composite structure exhibiting emergent behaviour.

Subclass of: Resource

Comment: Can consist of purely human elements. A system is stable and maintains itself this way - the constituent parts must therefore collectively provide the mechanism to keep the system stable. If an essential part of a system is removed it destroys that system (it might become a different system because the system boundary is then different). As ever “the whole is more than the sum of the parts”
