UBERON:0023867 islands of Calleja of olfactory tubercle, relationship and taxon constraint

Dear Uberon Team,

Regarding UBERON:0023867 (islands of Calleja of olfactory tubercle):

relationship: part_of UBERON:0001881 {source="NIFSTD"} ! island of Calleja
relationship: part_of UBERON:0001883 {source="NIFSTD"} ! olfactory tubercle

As far as I understand, the relationship to UBERON:0001881 (island of Calleja) should be is_a rather than part_of.

In addition, it seems that the current relationship structure may, through inference propagation, produce the assertion that:

islands of Calleja of olfactory tubercle part_of nucleus accumbens,

which appears to be incorrect.

To prevent this, I believe that UBERON:0023867 (islands of Calleja of olfactory tubercle) requires a taxon constraint similar to the one already present for UBERON:0001881 (island of Calleja), for example:

relationship: part_of UBERON:0001883 {gci_relation="part_of", gci_filler="NCBITaxon:9989", source="MP"} ! olfactory tubercle

Could you please review whether an appropriate taxon constraint should be added for UBERON:0023867 as well?

Thank you in advance for your help.

Best regards,

Start by reviewing the axioms for UBERON:0023867 and comparing them with UBERON:0001881, especially the proposed is_a relationship and taxon constraint. Check whether the current relationships infer a part_of link to the nucleus accumbens; the work is done when the reviewed ontology structure avoids that incorrect assertion.
