IFA015 v0.4.0 released May’16 :
Uses full OpenModel Profile
Use same version of Papyrus and
profile as ONF, ITU-T, MEF.
Profile being adopted by TM Forum
Provide overall view of the information, showing relations
Provide coherence of the information and semantic alignment
Allow for automation of generation of either interface
specifications or different data models
Simplify information exchanges with others organisations
