[Carbon-dev] Using input parameters with RDF data services

[Isuru Suriarachchi]

Hi Amani,

I just tried out the RDF data service at [1]. Sample works fine, but it
looks like the query doesn't use the input parameter. With SQL queries we
can pass input parameters into the query using ":input" notation. How can I
pass input parameters into the following Sparcl query which is used in the
sample?

PREFIX space: <http://purl.org/net/schemas/space/>
PREFIX relevance: <http://a9.com/-/opensearch/extensions/relevance/1.0/>
PREFIX foaf: <http://xmlns.com/foaf/0.1/>
PREFIX dc: <http://purl.org/dc/elements/1.1/>

SELECT ?homepage ?name ?alternateName ?internationalDesignator ?mass
?score ?launch ?agency ?description
WHERE {
  ?craft foaf:homepage ?homepage.
  ?craft foaf:name ?name.
  ?craft space:alternateName ?alternateName.
  ?craft space:internationalDesignator ?internationalDesignator.
  ?craft space:mass ?mass.
  ?craft relevance:score ?score.
  ?craft space:launch ?launch.
  ?craft space:agency ?agency.
  ?craft dc:description ?description.
}

Thanks,
~Isuru
