OBO: 1.3 Whiteboard
This page is intended to be a scratch pad for OBO 1.3 features and proposals.
Changes to Relations
The following new Typedef tags should be supported in OBO 1.3...
transitive_under means that p -transitive_under-> q and X -q-> Y and Y -p-> Z, then X -p-> Y. Note that every relation is automatically transitive_over and transitive_under IS_A
always_implies_inverse is a boolean property. If always_implies_inverse is true for a relation p, it means that if p -inverse_of-> q and X -p-> Y, then Y -q-> X. This property could be used to define an integral_part_of relationship in OBO_REL, for example:
[Typedef] id: OBO_REL:part_of name: part of inverse_of: has_part [Typedef] id: OBO_REL:has_part name: has part [Typedef] id: OBO_REL:integral_part_of is_a: OBO_REL:part_of always_implies_inverse: true
