1. Introduction

This section is non-normative.

This specification defines a vocabulary for Tracked Resource Sets.

Note that this document is informative; the normative document for the vocabulary is the machine-readable source in [VOCAB].

1.1 Typographical Conventions and Use of RFC Terms

This section is non-normative.

As well as sections marked as non-normative, all authoring guidelines, diagrams, examples, and notes in this specification are non-normative. Everything else in this specification is normative.

The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT", "SHOULD", "SHOULD NOT", "RECOMMENDED", "NOT RECOMMENDED", "MAY", and "OPTIONAL" in this specification are to be interpreted as described in BCP 14 [RFC2119] [RFC8174] when, and only when, they appear in all capitals, as shown here.

1.2 Vocabulary Terms

1.2.1 RDF Vocabulary for Tracked Resource Set

1.2.1.1 Vocabulary Details

The namespace URI for this vocabulary is: http://open-services.net/ns/core/trs#

The OSLC Core Tracked Resource Set vocabulary defines terms used in describing Tracked Resource Sets.

1.2.1.1.1 Classes in this namespace (6)

Base, Change Log, Creation, Deletion, Modification, Tracked Resource Set

Base

http://open-services.net/ns/core/trs#Base

Base is an RDFS class.

A Base identifies the initial set of resources in a Tracked Resource Set.

Change Log

http://open-services.net/ns/core/trs#ChangeLog

Change Log is an RDFS class.

A Change Log describes what resources have been created, modified or deleted, and when.

Creation

http://open-services.net/ns/core/trs#Creation

Creation is an RDFS class.

Represents a resource creation or modification change event.

Deletion

http://open-services.net/ns/core/trs#Deletion

Deletion is an RDFS class.

Represents a resource deletion change event.

Modification

http://open-services.net/ns/core/trs#Modification

Modification is an RDFS class.

Represents a resource creation or modification change event.

Tracked Resource Set

http://open-services.net/ns/core/trs#TrackedResourceSet

Tracked Resource Set is an RDFS class.

A Tracked Resource Set provides a representation of the current state of a Resource Set.

1.2.1.1.2 Properties in this namespace (12)

base

http://open-services.net/ns/core/trs#base

base is an RDF property.

An enumeration of the Resources in the Resource Set.

beforeETag

http://open-services.net/ns/core/trspatch#beforeETag

beforeETag is an RDF property.

HTTP entity tag of resource immediately before this change.

change

http://open-services.net/ns/core/trs#change

change is an RDF property.

The Change Event entries.

changed

http://open-services.net/ns/core/trs#changed

1.3 Conformance

OSLC TRS Servers MUST use the vocabulary terms defined here where required, and with the meanings defined here. Servers MAY augment this vocabulary with additional terms. [CC-1]
