ResourceMap-class: ResourceMap provides methods to create, serialize and deserialize an OAI ORE resource map.

Description

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.

Slots

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

Methods

• 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.
