Dear all,
Till now we had no rules to provide backward compatibility so for sure some (many) of the Geris will not follow this no rule.
In addition, we have concern because guides are directly in the wiki page while often they are in pdf format in other communities. So we have the pdf files for previous versions because we delivered them as deliverables but they are not reachable or not associated in the catalogue to the previous version but we can solve it…
Till now we were more in a project mode that in a community mode so we could apply new rules now and explain that minor releases should provide backward compatibility or if not provide a clear support duration for previous versions. And in this case we have also to list the new features or bugs we have solved to attract also new users on the new version.

Actually, I have the opposite perception -- I would be surprised if there are many GEris which *do* guarantee backwards compatibility (and transparent upgrades).. Of course, I like surprises :-)

dear juanjo and all,
unfortunately i cannot attend in person (i'll follow the minutes while the meeting is ongoing) while alessandra and davide will.
btw, i think latest(s) version(s) must be kept if there is no backward compatibility, as this is normal professional practice. indeed, a technology supplier cannot force its clients to change to a newer version without suitable free support! of course old versions do not eveolve, but for a certain period of time bugs fixing should be guaranteed...
of course, we should know who is using what, not only for the past but for current geris, this is something we have to put in place.
of course i'd suprised, particularly in our (fiware) case, if there are many geris which do not guarantee backward compatibility.
i can understand for cosmos, but for several others this would (should?) not be the case.
ciao,
stefano

Let's try to discuss this in our weekly confcall, please add this point as item in the agenda.
In the meantime, I would encourage you to make a proposal.
I tend to think we should just provide support of the latest version:
* Regarding most of the GEris of the Data/Media Context Management chapter, it shouldn't be a big deal to ask users to update the version of the GEris they are using to the most recent version because such updates shouldn't be so difficult to install and configure. Probably the only exception would be the BigData GEri, with which I believe that support of versions is very much tied to the support of the underlying technology (Hadoop).
* Regarding most of the GEris of the IoT Services Enablement, the Advanced Web-based UI and the Apps/Data delivery chapters, I believe that similar argument may apply, but I would like to hear Thierry/Carlos, Philipp, and Alessandra/Javier, respectively. Regarding the Apps/Data Delivery chapter I believe that most users should try to experiment with GEris deployed globally on FIWARE Lab and used "as a Service" and we should recommend that (remember the note we asked them to incorporate in entries of the Catalogue), therefore I would say that we should just support the version that is offered globally as a Service, even for local deployments.
* Regarding GEris of the Cloud, Security and I2ND (network) chapters, which are more kind of "infrastructure" GEris, I believe that we should encourage usage of what is on the FIWARE Lab and we should just support the versions of what is supported there as part of the infrastructure
* Regarding GEris linked to the middleware (KIARA) and robotics in the I2ND chapter, which are not yet available I believe that the same reasoning as with GEris of the Data/Media Context Management should apply but I would like to hear Pier/Thomas.
Given said the above, I believe that we should document these policies in the entries of the FIWARE Catalogue corresponding to each FIWARE GEri. Probably adding a new tab on the matter ("Support" ?)
Let's add this as an item on the agenda of our Monday meeting and discuss this offline in the meantime.
Best regards,
-- Juanjo

Dear Juanjo, all,
While this is definitely a step in the right direction, I think we need to clarify the exact impact on the GEi users.
More specifically, do we need to maintain proper versions of the GEis? Should users be able to download & install older versions? Do we need to *support* older versions? For how long? How about documentation associated with older versions? What should be the approach wrt upgrades and backwards-compatibility? Would it be different for different GEis, or different groups of GEis? (e.g., global instances versus those installed manually versus those installed via Cloud tools)
These questions will be critical as more people start using our GEis.
Thanks,
Alex

Dear all,
It seems that our repositories are not always well aligned and part of this is caused by the lack of flexibility in the procedures. We have decided to give it a push by relaxing the current work procedure.
This was triggered by finding that some partners have new versions of code (R3.4 , for instance) and the manuals were the old ones for R3.3.
Those partners with GEris to be published on the catalogue (those on [1]) must ensure consistency with the latest release delivered:
* Ensure that the latest version is available in a repository clearly linked from the catalogue in the Downloads tab(Files, github or whatever you use)
* Update the Installation and admin manual on the public wiki directly and make sure that it is referred from the catalogue
* Update the User & Programmer manual on the public wiki directly and make sure that it is referred from the catalogue
* Update the Unit Testing Plan manual on the public wiki directly and make sure that it is referred from the catalogue
* Update the FIWARE Lab recipes, images, etc. if needed
* Update the FIWARE Academy courses (http://edu.fi-ware.org/) if needed
The only step on which we will keep applying supervision is publication of VM images, deployment recipes, etc. on FIWARE Lab.
The catalogue has a workflow that still implies approvals of edited entries but Stefano will try to swiftly approve your edits until we implement a more agile workflow (under definition).
From now on, updating the software means updating everything and keeping it in perfect synchrony. It can be done anytime, at the end of every Sprint or even in its middle (e.g., due to a hot patch it is urgent to publish). The manuals and info must correspond to the same release always. To avoid temporary inconsistencies, we ask you to prepare everything offline in the most suitable repository in each case(word, private wiki, etc.) and port it all in one go to the all the repositories.
The Security chapter is still backdated (in R2) and R3 will be ported to the public wiki by Thales shortly. You will have to internally coordinate in Security to publish all your stuff in an orderly fashion.
Note that with all these measures we are giving you a lot of empowerment. We will implement a methodology that will mean that such empowerment will remain for those partners who show they are reliable. However, a given FIWARE GEri owner or even a complete chapter may loose this empowerment and it will be put in quarantine (i.e., activities under close supervision and strict approval procedures) if it is find out that general rules, templates, etc are not followed or provided content is not of enough good quality.
Best regards,
Miguel and Juanjo
