Hi, Tags are workflows/working copies, so I guess you’re not using them.
Blank nodes are perfectly normal in the result of a query. You just don't put them into SPARQL when writing a new query. It’s only the data at the other end of something with a blank node subject that is of interest. Just leave the places with blank node values as ?<something> in a single larger query and move on to find the items of interest via their predicate (aka property e.g. so to find what was added by a change: ?change teamwork:added ?added . ?added teamwork:subject <http://example/ <http://example/>something> ?added teamwork:predicate skos:prefLabel ?added teamwork:object “Antartica_Updated”. Where ?added is a variable that just happens to result in a blank node if returned. Don’t return the blank node, just return the data of interest. The above tells you that: <http://example/ <http://example/>something> skos:prefLabel “Antartica_Updated” . was added to the graph. Delete works in a similar way. FWIW the little SPARQL I sent you was just so you couild query the data and see what data exists and what properties they have and write the SPARQL you need, it was not in any way a solution to your problem as only you know your requirements.
