I am not sure what digest you mean but the fuaeki graphs do have an isomorphism check so you could compare compare construct results. Claude On 9 Dec 2017 04:11, "Dan Davis" wrote: > So, this is what I was asking about earlier. With small graphs, e.g. > DESCRIBE <>, the algorithms for grap

So, this is what I was asking about earlier. With small graphs, e.g. DESCRIBE <>, the algorithms for graph isomorphism that support blank nodes should be good. rdflib includes an implementation, and I wish I knew whether there is an implementation of that digest algorithm for Jena. On Fri,
