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

ResourceMap-class.Rd
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 objectsworld
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.
Examples
dp <- new("DataPackage")
dp <- insertRelationship(dp, "/Users/smith/scripts/genFields.R",
"http://www.w3.org/ns/prov#used",
"https://knb.ecoinformatics.org/knb/d1/mn/v1/object/doi:1234/_030MXTI009R00_20030812.40.1")
relations <- getRelationships(dp)
resMap <- new("ResourceMap")
resMap <- createFromTriples(resMap, relations, getIdentifiers(dp))
if (FALSE) { # \dontrun{
tf <- tempfile(fileext=".rdf")
serializeRDF(resMap, file=tf)
} # }
