ONAP R4 Modeling High Level Requirements

Based on timeplan of modeling subcommittee, high level requirements need to be finished by M0/M1,

There are 4 categories of high level requirement,

1) Will be implemented and included in the release 4
2) Documentation after implemented, or implemented but not in the release
3) Lower Priority
4) Experimental

The first category is that those requirement will be implemented and commited by the impacted projects in this release

the second category will document the current implementation in those projects.

Other two categories like lower priority and experimental will not be included in the release 3, the contributor will work with best effort to influence future release.

Owners of each requirement needs to coordinate the modeling spec commitment and code commitment with PTLs of impacted project.

1) Will be implemented and included in the release 4

Per discussion in Paris, requirements can be based on:

Release / project specific needs
Recognized 'future' needs
Documenting existing models

Some concepts may be complex enough, if we wait for the release / project requirement, we will be too late to properly develop the concept.

the committee agreed

1) Thinh Nguyenphu (Unlicensed) will lead 1st task force working on #1,#2 recommendations:

Recommend#1: member companies prepare and submit these additional extension to ETSI NFV IFA and SOL WG toward v2.6.1 or later. (agreed) Recommend#2: ONAP adopts SOL001 Type extension method, per clause 5.6 (agreed)

2) Former user (Deleted) victor gao will lead 2nd task working on $4 recommendation:

Recommend #4: SDC supports SOL001 v2.5.1 type definitions (VNFD, PNFD, NSD) (agreed)

3) Thinh Nguyenphu (Unlicensed) will report NSD comparision with service csar in 2 weeks,

All 3 work will be reported to Anatoly weekly DM conference call, Anatoly will ask final approval from Modeling subcommittee
