Inter-service dependency stability & Feedback for SSA implementers

Hi all, I'm not involved in the WP5 work nor in the services SA/SSA implementation but, since we are currently focusing on the implementation, debugging and validation of the french pilot's SSAs, we can say the task is not realy facilitated since we lack of KE stability and KE feedback. Maybe I could be wrong but the following points could constitute "a must have" for us in such conditions:

• We are surprising the KE seems to be out of running if one or several services are out of game. If so, it is urgent to improve the robustness to avoid dependency between services.
• The KE seems to be designed to provide service "integration" debugging feedback whereas we should have (also ?) an "implementation" debugging level including feedbacks pointing real issues; i.e., datails on results of the possible knowledge interaction showing possible mapping between graph patterns of 2 services that try to have interactions and can have missing parameters or missing service to put in front, etc.

If those two issues have already been raised somewhere else, please forget them or then, try to bring an answer. Thanks for your feedback.

Kind regards, Frederic Mesureur (Trialog)

Hi Frederic, thanks for taking the time to give us feedback!

Regarding your first bullet point I have two remarks:

• We are working on detecting inactive Knowledge Bases and making sure they no longer obstruct the data exchange (see issue https://gitlab.inesctec.pt/interconnect/knowledge-engine/-/issues/317). We agree that this unexpected behavior should not happen.
• We encourage SSA (i.e. Knowledge Base) developers to follow the best practice to unregister (DELETE /sc) your Knowledge Base whenever the service is no longer connected.

About your second bullet point about "integration versus implementation" debugging features; we agree that debugging features in general should improve. I do not fully understand the integration/implementation distinction you are referring to; could you also give an example of the "integration" debugging features that you mention are already available? Internally, we indeed have some tools that are "showing possible mapping between graph patterns of 2 services" and ideally they become available for everyone via the Knowledge Explorer in the Service Store. Unfortunately, we have not been able to give this priority yet, but to make it concrete I've created an issue for this here: https://gitlab.inesctec.pt/interconnect/service-store-frontend/-/issues/94

Please do not hesitate if you have more remarks/questions!

Kind regards,

Barry

Hi Barry, thanks for your detailed answers.

The first point improvement is already on rails and we will follow your best practices to unregister KB when unused.

The second point is aleready opened with your issue service-store-frontend#94 raised on the service store front-end. My initial idea (if relevant) would be to automatically provide knowledge explorer debugging information when you try knowledge interactions between 2 services and the matching is not (completely ?) possible for any reason providing what I call an implementation debugging level feedback. Maybe associate knowledge explorer capabilities with knowledge engine feedbacks requires tremendous effort to provide that level of feedback to help implementers. Even though not easy to explain, I hope it is clear enough.

Kind regards, Frederic

Hi Frederic, thanks for the feedback. I've added your debugging description to service-store-frontend#94 so that we can take it into account.

Do you prefer to keep this issue #323 open until #317 is in PRODUCTION? Or shall we close this issue and you reopen (or make a new one) if the problem persists after a new release?

Best regards, Barry

Hi Barry, please keep issue #323 open since service-store-frontend#94 is still linked to it. Kind regards, Frederic

Closing this, since #317 is closed. Please keep an eye on service-store-fronted#94, since it is still open.
