Table of Contents
How to use
Install by pip.
pip install SPARQLTransformer
Use in your JS application (node or browser).
from SPARQLTransformer import sparqlTransformer
out = sparqlTransformer(query, options)
The first parameter (query
) is the query in the JSON-LD format. The JSON-LD can be:
- an already parsed JS object (or defined real time),
- ONLY if running in NodeJS, the local path of a JSON file (that will then be read and parsed).
The options
parameter is optional, and can define the following:
OPTION | DEFAULT | NOTE |
---|---|---|
context | http://schema.org/ | The value in @context . It overwrites the one in the query. |
sparqlFunction | None |
A function receiving in input the transformed query in SPARQL, returning a Promise. If not specified, the module performs the query on its own1 against the specified endpoint. |
endpoint | http://dbpedia.org/sparql | Used only if sparqlFunction is not specified. |
debug | False |
Enter in debug mode. This allow to print in console the generated SPARQL query. |
See test.js
for further examples.
