View Source SPARQL.Query.Result.Format behaviour (SPARQL.ex v0.3.10)
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
modules under the 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.
