This vocabulary defines a set of terms for describing changes to resource descriptions. [en]
The vocabulary introduces the notion of a ChangeSet which encapsulates the delta between two versions of a resource description. In this context a resource description is the set of triples that in some way comprise a description of a resource. The delta is represented by two sets of triples: additions and removals. A ChangeSet can be used to modify a resource description by first removing all triples from the description that are in the removals set and adding the triples in the additions set. [en]

Things are a member of this class if they are the value of PrecedingChangeSet.

Status

Status

ChangeReason

URI: http://purl.org/vocab/changeset/schema#changeReason

a short, human readable description of the purpose for the changeset

Semantics

Status

PrecedingChangeSet

URI: http://purl.org/vocab/changeset/schema#precedingChangeSet

This property can be used to build a history of changes to a particular resource description. The first ChangeSet in the history will have no precedingChangeSet property. Each subsequent ChangeSet added to the history references the preceding one resulting in a singly-linked list of changes. Care must be taken not to introduce cycles in the history.

Semantics

Having this property implies being a ChangeSet. Every value of this property is a ChangeSet.

Status

Removal

URI: http://purl.org/vocab/changeset/schema#removal

By convention the subject of the triple being removed should be the same as the subjectOfChange

Semantics

Having this property implies being a ChangeSet. Every value of this property is a rdf:Statement. It is a sub-property of Statement.

Status

Statement

URI: http://purl.org/vocab/changeset/schema#statement

a triple included in this set of changes

Semantics

Having this property implies being a ChangeSet. Every value of this property is a rdf:Statement.

Status

SubjectOfChange

URI: http://purl.org/vocab/changeset/schema#subjectOfChange

the resource to which this set of changes applies

Semantics
