1. Introduction

This section is non-normative.

This specification defines a vocabulary for the OSLC Requirements Management resources. The intent is to define resources needed to support common integration scenarios and not to provide a comprehensive definition of a Requirement. The resource formats may not match exactly the native models supported by requirement management service providers, but are intended to be compatible with them. The approach to supporting these scenarios is to delegate operations, as driven by service provider contributed user interfaces, as much as possible and not require a service provider to expose its complete data model and application logic.

1.1 Terminology

This section is non-normative.

Terminology is based on OSLC Core Overview [OSLCCore3], W3C Linked Data Platform [LDP], W3C's Architecture of the World Wide Web [WEBARCH], Hyper-text Transfer Protocol [HTTP11]. Terminology for this specification is defined in part 1 of the multi-part specification.

1.3 Typographical Conventions and Use of RFC Terms

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, SHOULD, SHOULD NOT, RECOMMENDED, MAY, and OPTIONAL in this specification are to be interpreted as described in [RFC2119].

In addition to the namespace URIs and namespace prefixes oslc, rdf, dcterms and foaf defined in the OSLC Core specification, OSLC RM defines the namespace URI of http://open-services.net/ns/rm# with a namespace prefix of oslc_rm

3. Requirements Management Vocabulary Terms

This specification defines the root superclasses, properties and values. Servers may define additional subclasses and provide additional properties as needed.

3.1 Vocabulary Details

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

All vocabulary URIs defined in the OSLC Requirements Management (RM) namespace.

3.1.1 Classes in this namespace (2)

Requirement, RequirementCollection

Requirement

http://open-services.net/ns/rm#Requirement

Requirement is an RDFS class.

Statement of need.

RequirementCollection

http://open-services.net/ns/rm#RequirementCollection

RequirementCollection is an RDFS class.

Collection of requirements. A collection uses zero or more requirements.

3.1.2 Properties in this namespace (15)

affectedBy, constrainedBy, constrains, decomposedBy, decomposes, elaboratedBy, elaborates, implementedBy, satisfiedBy, satisfies, specifiedBy, specifies, trackedBy, uses, validatedBy

affectedBy

http://open-services.net/ns/rm#affectedBy

affectedBy is an RDF property.

Expresses an affects relationship between entities, where the object entity in some way affects the subject entity. For example, a requirement is affected by a defect.

constrainedBy

http://open-services.net/ns/rm#constrainedBy

constrainedBy is an RDF property.

Expresses a constraining relationship between entities, where the object entity constrains the subject entity. For example, a functional requirement is constrained by a safety requirement.

constrains

http://open-services.net/ns/rm#constrains

constrains is an RDF property.

Expresses a constraining relationship between entities, where the subject entity constrains the object entity. For example, a safety requirement constrains a functional requirement.

decomposedBy

http://open-services.net/ns/rm#decomposedBy

decomposedBy is an RDF property.

Expresses a decomposition relationship between entities, where the object entity decomposes the subject entity. For example, a system requirement is decomposed into a collection of system requirements.

decomposes

http://open-services.net/ns/rm#decomposes

decomposes is an RDF property.

Expresses a decomposition relationship between entities, where the subject entity decomposes the object entity. For example, a collection of system requirements decompose a system requirement.

elaboratedBy

http://open-services.net/ns/rm#elaboratedBy

elaboratedBy is an RDF property.

Expresses an elaboration relationship between entities, where the object entity elaborates the subject entity. For example, a requirement is elaborated by a model element.

elaborates

http://open-services.net/ns/rm#elaborates

elaborates is an RDF property.

Expresses an elaboration relationship between entities, where the subject entity elaborates the object entity. For example, a model element elaborates a requirement.

implementedBy

http://open-services.net/ns/rm#implementedBy

implementedBy is an RDF property.

Expresses an implementation relationship between entities, where the object entity is a necessary or desirable aspect of an implementation of the subject entity.

satisfiedBy

http://open-services.net/ns/rm#satisfiedBy

satisfiedBy is an RDF property.

The subject is satisfied by the object. For example, a user requirement is satisfied by a system requirement.

satisfies

http://open-services.net/ns/rm#satisfies

satisfies is an RDF property.

Expresses a relationship between entities, where the subject entity satisfies the object entity. For example, a system requirement satisfies a user requirement.

specifiedBy

http://open-services.net/ns/rm#specifiedBy

specifiedBy is an RDF property.

Expresses a specification relationship between entities, where the object entity further clarifies or specifies the subject entity. For example, a requirement is specified by a model element.

specifies

http://open-services.net/ns/rm#specifies

specifies is an RDF property.

Expresses a specification relationship between entities, where the subject entity further clarifies or specifies the object entity. For example, a model element specifies a requirement.

trackedBy

http://open-services.net/ns/rm#trackedBy

trackedBy is an RDF property.

Expresses a tracking relationship between entities, where the object entity in some way tracks or governs the evolution of the subject entity. For example, a requirement may be said to be tracked by a change request, in that it governs the changes to a requirement according to some process machinery.

uses

http://open-services.net/ns/rm#uses

uses is an RDF property.

Expresses a use relationship between entities, where the object entity is used by the subject entity. For example, a requirement collection may use a requirement.

validatedBy

http://open-services.net/ns/rm#validatedBy

validatedBy is an RDF property.

Expresses a validation relationship between entities, where the object entity in some way validates the subject entity. For example, a requirement collection may be said to be validated by a test plan.
