-=Open issues=
-==Proposed new relations==
-The lacks family of relations is being discussed
-Next we will be examining:
-has_function, has_quality, and relations that deal with creation, consumption and development
-The derives_from relation has been criticised from an ontological POV (REF?). There is also the terminological problem that "derives_from" is used specifically for evolutionary relationships by some. We will report back on this after the september NCBO anatomy meeting. We may create a "develops_from" parent for transformation_of corresponding to how that relation is currently used in MOD AOs
-==Hunter/Bada Proposal for new relations==
-We propose the addition of nine new relationships (and nine additional inverse relationships) to the RO.   The relationship are defined and linked to the existing relationships in this OBO file [[media:Hunter_Bada_OBO_relationship_proposal.zip]].   Each of our proposed relationships has a range over the GO biological process hierarchy, although with varying domains, mostly over continuants.
-Perhaps the most basic of these is intended to capture the idea of a process leading to a change in a continuant: <process> results_in_change_in <continuant>  (see the above linked OBO file for formal definitions).  We also propose two more specific versions of this when the continuant is either the thing changed (results_in_change_from) or the thing that results from the change (results_in_change_to).
-In addition, we propose well over 1000 instances of these relationships among terms from the GO, ChEBI and CTO ontologies.  For example, we identified 30 instances of a <GO Biological Process>
-results_in_change_in <ChEBI term>, 13 instances where <GO:BP> results_in_change_in <GO:CC> and 41 instances where <GO:BP> results_in_change_in <CTO term>.   The more specific relationships are actually more prevalent: we propose 593 instances of <GO:BP> results_in_change_to <ChEBI term>
-The other relationships we propose are:
-* results_in_capability_to_change_to
-* results_in_directed_movement_of
-* results_in_division_of
-* results_in_joining_of
-* results_in_perception_of
-* results_in_regulation_of
-Definitions of each and positions in the RO hierarchy are in the OBO file.
-We've posted a message with the subject "Hunter/Bada Proposal for New Relations" on the relationship-ontology mailing list describing our rationales for these in more detail.
-==OWL Conversion==
-The standard GO obo->owl conversion is used. See [[OboInOwl:Main_Page]] for details
-obo1.2 defines "builtin" tags for relations that are hardwired into the obo semantics - is_a and instance_of are tagged builtin. These are not exported in OWL, as these are also part of the OWL language
