Constructor Detail

Graph

public Graph(mixed uri, mixed credentials, mixed request_factory)

Create a new instance of this class

Param:

string uri URI of the graph

Credentials credentials the credentials to use for authenticated requests (optional)

Method Detail

apply_changeset

public void apply_changeset(mixed cs)

Apply a changeset to the graph

Param:

ChangeSet cs the changeset to apply

Return:

HttpResponse

apply_changeset_rdfxml

public void apply_changeset_rdfxml(mixed rdfxml)

Apply a changeset to the graph

Param:

string rdfxml the changeset to apply, serialised as RDF/XML

Return:

HttpResponse

apply_versioned_changeset

public void apply_versioned_changeset(mixed cs)

Apply a changeset in a versioned manner to the graph

Param:

ChangeSet cs the changeset to apply

Return:

HttpResponse

apply_versioned_changeset_rdfxml

public void apply_versioned_changeset_rdfxml(mixed rdfxml)

Apply a changeset in a versioned manner to the graph

Param:

string rdfxml the changeset to apply, serialised as RDF/XML

Return:

HttpResponse

describe

public void describe(mixed uri, mixed output)

Obtain the graph's bounded description of a given resource

See:

http://n2.talis.com/wiki/Metabox#Describing_a_Resource

Param:

string uri the URI of the resource to be described

string output the desired output format of the response (e.g. rdf, xml, json, ntriples, turtle)

Return:

HttpResponse

describe_to_simple_graph

public void describe_to_simple_graph(mixed uri)

Obtain the graph's bounded description of a given resource. This is designed to be fast since it uses RDF/JSON which requires no parsing by the SimpleGraph class. This method always returns a SimpleGraph, which will be empty if any HTTP errors occured.

See:

http://n2.talis.com/wiki/Metabox#Describing_a_Resource

Param:

string uri the URI of the resource to be described

Return:

SimpleGraph

describe_to_triple_list

public void describe_to_triple_list(mixed uri)

Obtain the graph's bounded description of a given resource

Deprecated:

triple lists are deprecated

has_description

public void has_description(mixed uri)

Tests whether the graph contains a bounded description of a given resource. This uses a conditional GET.

See:

http://n2.talis.com/wiki/Metabox#Describing_a_Resource

Param:

string uri the URI of the resource to be described

Return:

boolean true if the graph contains triples with the resource as a subject, false otherwise

submit_rdfxml

public void submit_rdfxml(mixed rdfxml)

Submit some RDF/XML to be added to the graph

Param:

string rdfxml the RDF to be submitted, serialised as RDF/XML

Return:

HttpResponse

submit_turtle

public void submit_turtle(mixed turtle)

Submit some Turtle to be added to the graph

Param:

string turtle the RDF to be submitted, serialised as Turtle

Return:

HttpResponse
