Crystal Pool:SPARQL query service

Most content of this page should be much alike to wikidata:Wikidata:SPARQL query service, except for the following:

• SPARQL query service GUI (Gray Wing) is here: https://q.crystalpool.cxuesong.com/
• SPARQL Endpoint: https://q.crystalpool.cxuesong.com/sparql
  • Use POST method to send your SPARQL query as request body
  • This endpoint does not support HTTP GET requests

If you are new to this, note that Crystal Pool uses Wikibase, the same MediaWiki extension as in Wikidata. You can found their SPARQL language guide on Wikibooks. You may also take a look at wikidata:Wikidata:SPARQL query service#Learning SPARQL. Basically the query syntax and even the namespace prefixes are the same with Wikidata. However, later wd: might be replaced with cp:.
