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 format. The JSON can be:
- an already parsed (or defined real time)
dict, - 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 tests.py for further examples.
