rdf-cronify

This module adds timestamps to RDF graphs and pushes them to a store.

Usage

All methods are available as instance and member methods.

• addTimestamp(graph, subject, [timestamp]): Adds a timestamp to the graph for the given subject. The current time is used if no timestamp is given. Does nothing if there is already a timestamp.
• createCronifiedIri(containerIri, timestamp): Creates an IRI based on the container IRI and a clean string of the timestamp.
• createTimestampLiteral([timestamp]): Creates a literal with a datatype for the given timestamp. The current time is used if no timestamp is given.
• store((store, subject, container, graph)): Adds the graph to the store and creates a link in the container graph to the cronified graph. If the graph/subject does not contain a timestamp addTimestamp must be called before.

A new instance of Cronify is only required if some properties need to be customized. The constructor accepts an options object with the following properties:

• timestampPredicate: (default: NamedNode('http://purl.org/dc/elements/1.1/date'))
• timestampDatatype: (default: NamedNode('http://www.w3.org/2001/XMLSchema#dateTime'))
• containerPredicate: (default: NamedNode('http://www.w3.org/ns/hydra/core#member'))
