SPARQLProtocolProxy is a small proxy server based on Python's BaseHTTPRequestHandler and exposes a SPARQL protocol interface not so strictly following the W3C recommendation (http://www.w3.org/TR/rdf-sparql-protocol/).
What it does
SPARQLProtocolProxy supports any SPARQL-based triple store that rdflib and SuRF support and makes it accessible through the standardized SPARQL protocol interface:
- rdflib IOMemory
- MySQL (rdflib 2.4.2)
- AllegroGraph
- Sesame2
- any SPARQL protocol compliant store, and many more.
This server supports CORS, see http://enable-cors.org/.
You might want to use Deniz (http://github.com/cburgmer/deniz) to query data exposed by this proxy.

$ python sparqlprotocolproxy.py --cors --port 8000
