[bioontology-support] SPARQL Endpoint not showing certain relationships for OBO data

Dear Bioontology Support,

I am a new user, and was testing out the SPARQL endpoint for Bioportal. I find that some of the relationships in some ontologies are missing from the SPARQL view.

Using the Adult  Mouse Anatomy (MA) ontology from OBO, I used the query


  MA:0002419 ?p ?o

I do not find any entries linking it to MA:0000127, which it should from the obo file.

id: MA:0002419
name: pancreatic islet core
synonym: "beta cell islet" RELATED []
xref: EMAPS:3565328
relationship: part_of MA:0000127 ! pancreatic islet

It only shows a subClassOf relationship to

What is this object and is this an error or am I querying incorrectly?

Thank you,

Hok Hei Tam
