QUESTION
From one RDF file containing statements about multiple chemical compounds, I would like to create one RDF file per chemical compound.
In order to do that, I started off looking for a SPARQL query that can isolate all triples linked to a certain URL, no matter how much nodes are in between.
I started off with a very interesting SPARQL query (https://stackoverflow.com/a/33290642/5433896) such that it would return (hopefully) all triples linked to a chemical compound :d1
in my dataset, but NOT about another compound :d10

ANSWER
Answered 2019-Jun-18 at 16:22I found out the answer to this question when adding extra things I had already noticed.
Since :d1 rdf:type :Compound
and :d10 rdf:type :Compound
, there is actually a path from :d1
to :d10
and therefore triples about :d10
also end up in my query results - which is of course not what I wanted.
Looking at the query, I thought it would make sense to add an additional constraint that ?child
mustn't be :d10
. And, thinking about the way the poster of https://stackoverflow.com/a/33290642/5433896 explained his query, I should also exclude that ?someSubj
or ?childPropVal
can be :d10
