Produces an RDF serialization of the nodes and relationships returned by the query.

Currently only RDF Turtle is supported. Also have a problem with supporting the showOnlyMapped parameter.

Examples

iex> cypher = TestGraph.LPG.read_query("node1.cypher").data
"match (n) return n limit 1\n"
iex> IO.puts (cypher |> NeoSemantics.Extension.cypher)
@prefix neovoc: <neo4j://defaultvocabulary#> .
@prefix neoind: <neo4j://indiv#> .


neoind:919 a neovoc:Resource;
  neovoc:rdfs__label "Hello World";
  neovoc:uri "http://dbpedia.org/resource/Hello_World" .

Produces an RDF serialization of the nodes and relationships returned by the query.

Currently only RDF Turtle is supported.

Examples

iex> cypher = TestGraph.LPG.read_query("nodes.cypher").data

iex> cypher |> NeoSemantics.Extension.cypher_on_rdf

Exports from Neo4j an LPG graph transformed into an RDF graph. The graph is centered on a node identified by node_id.

This returns the full context unless an optional boolean arg exclude_context is passed as true which will exclude context if present.

Examples

iex> NeoSemantics.Extension.node_by_id(1783)
"@prefix neovoc: <neo4j://defaultvocabulary#> .\n@prefix neoind: <neo4j://indiv#> .\n\n\nneoind:1783 a neovoc:Resource;\n  neovoc:ns0__creator neoind:1785;\n  neovoc:ns0__homepage neoind:1784;\n  neovoc:ns0__license neoind:1786;\n  neovoc:ns0__name "Elixir";

neovoc:uri "http://example.org/Elixir" .\n"

Exports from Neo4j an LPG graph transformed into an RDF graph. The graph is centered on a node identified by node_uri.

This returns the full context unless an optional boolean arg exclude_context is passed as true which will exclude context if present.

Examples

iex> NeoSemantics.Extension.node_by_uri("http://example.org/Elixir")
"@prefix neovoc: <neo4j://vocabulary#> .\n\n\n<http://example.org/Elixir> <http://example.org/creator> <http://dbpedia.org/resource/José_Valim>;\n  <http://example.org/homepage> <http://elixir-lang.org>;\n  <http://example.org/license> <http://dbpedia.org/resource/Apache_License>;\n  <http://example.org/name> "Elixir" .\n"

Pings the Neo4j service.

This returns a JSON confirmation that the service is up.

Examples

iex> NeoSemantics.Extension.ping
{"ping":"here!"}
