https://docbox.etsi.org/ISG/NFV/Open/Drafts/IFA015_NFV_Information_Model

Network Service as IFA015 Information Model


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
