RDF transform¶

This transform will render entities to a N-Triples string and embed it in the entity, which is then passed on to the transform chain.

Prototype¶

{
    "type": "rdf",
    "rdf-property": "rdf-property-to-use"
}

Properties¶

Property	Type	Description	Default	Req
`rdf-property`	String	The property that will hold any RDF generated		Yes

Example configuration¶

This is how a RDF transform would look like in the context of a pipe (source and sink configs omitted for brevity):

{
    "_id": "my-pipe",
    "transform": {
        "type": "rdf",
         "rdf-property": "rdf"
    }
}

Given the input entity:

{
  "_id": "x:1",
  "x:name": "Entity 1",
  "x:id": "entity-1",
  "foo:prop": [{
      "x:id": "child",
  }]
}

And these namespaces in the metadata configuration:

"namespaces": {
    "default": {
        "x": "http://x.org/",
        "foo": "http://foo.org/",
    }
}

it will produce the transformed entity:

{
  "_id": "x:1",
  "x:name": "Entity 1",
  "x:id": "entity-1",
  "foo:child": [{
      "x:id": "child",
  }]
  "rdf": "<http://x.org/1> <http://x.org/name> \"Entity 1\".\n<http://x.org/1> <http://x.org/id> \"entity-1\".\n<http://x.org/1> <http://foo.org/child> _:x1.\n_:x1 <http://x.org/id> \"child\".\n"
}
