SPARQL.ex v0.3.0 SPARQL.Query.Result.Format behaviour View Source

A behaviour for SPARQL query result formats.

A SPARQL.Query.Result.Format for a format can be implemented like this

defmodule SomeFormat do
  use SPARQL.Query.Result.Format
  import RDF.Sigils

  @id         ~I<http://example.com/some_format>
  @name       :some_format
  @extension  "ext"
  @media_type "application/some-format"
end

When @id, @name, @extension and @media_type module attributes are defined the resp. behaviour functions are generated automatically and return these values.

Then you'll have to do the main work by implementing a RDF.Serialization.Encoder and a RDF.Serialization.Decoder for the format.

By default it is assumed that these are defined in Encoder and Decoder moduler under the SPARQL.Query.Result.Format module of the format, i.e. in the example above in SomeFormat.Encoder and SomeFormat.Decoder. If you want them in another module, you'll have to override the encoder/0 and/or decoder/0 functions in your SPARQL.Query.Result.Format module.
