obsolete object property obsolete_is specified output of true Marked as obsolete by Allyson Lister. 0.3 There is an object property duplication for is specified output of, where one is from OBI (OBI_0000312) and one is from SWO (SWO_9000058); additionally, the reasoner infers these two object properties as equivalent. Both are the inverse properties for has specified output. It makes sense to retain the OBI object property. The SWO class URI was renamed to the OBI term URI (to make the moving of the axioms across to the OBI term simple), and then an SWO class with the original URI was marked as obsolete. Please use OBI_0000312 instead.
