I think Arian raises excellent questions in the context of D11.x. I also
think that we, as a consortium, don't have clear answers, and didn't
conduct a meaningful discussion to figure out whether we even have a
consensus or not. It seems that the answers would be tightly related to
the governance model being defined for the open source community. On the
other hand, maybe the relevant group to reach such a consensus would be
the (founding) members of the to-be-established Foundation, and not
necessarily the FI-Core consortium.
In more practical terms, if we decide to keep D11.x, it seems that
replicating the individual GE specifications there might be redundant, and
we may need to focus on architectural guiding principles.

Alex

Dear all,
Just to share Arian's reactions to our proposal to simplify the
deliverables. His answer is in my opinion rather reasonable.
Maybe we do not have time to analyse it and comment on it today but I
wanted to pass the info to all of you for the sake of transparency.
Regards,
Miguel

Dear Miguel,
Background: this is a response to some oral statements during the FI-WARE
review, where I expressed surprise that FI-Core had so many deliverables,
while at the same time the FI-WARE project was complaining about too many
deliverables.
Response:
- Overall, the reduction in the number and frequency of
deliverables is good
- D11.2-4: this is probably the most significant change. See
below.
- D11.5: drop D11.5.3. No change in schedule. Given the 1300
SMEs, the whole idea of the live demos (and its 200 PM effort) is to be
reconsidered, as repeated before.
- D.1<y>.1.(1,2): OK to move 1st issue to May/15.
- D.1<y>.6.(1,2,3,4): OK to make it annual.
- D.1<y>.8.<j>.(1,2): OK to merge with D.22.1.(1,2)
- D.21.x.(1,2): OK to merge
- D.22.x.(1,2) : OK to merge
- D31.5.x: OK to make it annual
- D.32.1.(1,2): OK for Sept+Dec 2015, with a draft at the time of
the first review
- D32.2 "Confidence-building framework": This is related to
proposing processes to evaluate the suitability of contributions [of new
enablers, by the open source community], based on a wide adoption by
application developers, and the consistency of such contributions to be
compliant with common rules. It also defines what the criteria in the
"Acceptance" boxes in presentations about the Open Source Community would
be. This cannot be skipped, but the information may be provided in other
deliverables.
- D33.2 "Expansion beyond Europe": the proposal is to leave this
to FI-Links completely. I guess this means only support to non-European
entities in the contract (to be confirmed).
Regarding D11.x:
- Without an overall architecture and roadmap, this change
basically means giving up on the "FIWARE is a COHERENT set of enablers"
vision, let alone the "FIWARE is a platform" strategy. FIWARE would then
be a set of enablers, without coherence.
- The integration / interoperability of GEs has always been a
question mark. Without overall architecture guidance, interoperability of
any combination of GEs is not per se designed in and integration of any
set of GEs, if required, is an issue for anyone taking up the enablers.
With no overall architecture, there are no sufficient mechanisms to assure
the interoperability of any set of GEs, other than what perhaps can be
done on chapter level, which will be partial at best and without any
overall guidance.
- This will have consequences for how to sell FIWARE. What does
it really mean to be a FIWARE enabler? FIWARE would become like a label
for passing certain acceptance tests, but not much more than that.
- Then, how would the Open Source Community choose the "accepted
FIWARE" specification of a certain functionality, if it can choose between
specification A and B? Certainly, the fit of any specification with
complementary, already accepted and to be defined FIWARE specifications
would be a major criterion (in addition to overall functionality, and
prerequisites such as sufficient quality, documentation, on FI-Lab, etc.).
It looks like the Open Source Community (or the Technical Committee
thereof) would make some arbitrary decisions here, not based on vision or
grand design, but at best on legacy.
- Then, what would be the argument for not having both
specifications A and B for a certain component/functionality? Would
overlaps be allowed? If so, again, FIWARE is reduced to a label. If not,
arbitrary and opaque decisions are around the corner.
- The consortium needs to ask itself what it means to be a FIWARE
enabler. There are some 'existential' questions to be answered.

Subject: Proposal for the simplification of the deliverables of FI-Core
Dear Arian,
After our interactions with you in the past FI-WARE review we have
concluded that it makes complete sense to take your offer and improve the
deliverables. We have been putting some time in discussing how to
reorganize the FI-Core deliverables with the focus on simplification. What
I am passing you now is just a proposal, some things you may agree with
and some others may need to stay as they are. In any case, part of the
deliverables at stake are ongoing work so coming to a swift conclusions
would help us to minimize delays.
This is what we propose:
·
https://docs.google.com/spreadsheets/d/1vEFqA7ZumHjgT1bcDl7nST_ZI7YfXILGTbjkIb-tgFU
We created a timeline with all the deliverables as they are now and added
column D with our proposal of change. The level of detail in the proposal
is not very high to make this manageable but we can send more details for
those changes that you may want to get better explained.
We look forward to your reply.
Kind regards,
Miguel
