Of the life of the CM WG and various other OSLC domain WGs we've been in
discussion on ways to best handle links, for example modeling them from an
outbound perspective of the current resource.
Time and experience has shown that this introduces statements which are
redundant, such as
(ChangeRequest1, oslc_cm:implementsRequirement, Requirement1)
which is exactly the same as saying:
(Requirement1, oslc_rm:implementedBy, ChangeRequest1).
This causes various problems around data duplication and ease of writing
queries. This motivation and best practices has been captured in Core WG
Link Guidance .
For the full list of CM (and other) predicates that are considered
redundant and the recommended predicates, see the full listing at .
For ease, here is the list of CM predicates proposed for consideration of
