ResourceMap-class | R Documentation |
The Open Archives Initiative Object Reuse and Exchange (OAI-ORE) defines standards for the description and exchange of aggregations of web resources, such as a DataPackage. A Resource Map describes the objects in a DataPackage and the relationships between these objects.
relations
value of type "data.frame"
, containing RDF triples representing the relationship between package objects
world
a Redland RDF World object
storage
a Redland RDF Storage object
model
a Redland RDF Model object
id
a unique identifier for a ResourceMap instance
initialize
: Initialize a ResourceMap object.
createFromTriples
: Populate a ResourceMap with RDF relationships from data.frame.
getTriples
: Get the RDF relationships stored in the ResourceMap.
parseRDF
: Parse an RDF/XML resource map from a file.
serializeRDF
: Write the ResourceMap relationships to a file.
