[Fiware-i2nd] R: Proposal for specification conventions (I2ND49)

[Garino Pierangelo]

Dear Marco,

thanks a lot for your contribution.

I have some comments/questions/doubts which I try to summarise here:

-          I'm not familiar with UML (it might sound strange, but I never had to use it in the past), so when you specify it is a modeling language 'mainly' used for design and specs of Object Oriented  software systems, do you mean that its use is not tied to that kind of programming paradigms/languages, but it can be adopted in a broader sense?

-          For this reason, is the use of class diagrams limiting us or not?

-          Don't we risk to adopt a top-down modeling approach which is not optimized for FI-WARE, where we already deal with existing portions of the system (i.e. the assets)?

-          Concerning point 1 in the suggested use of UML (summary at page 4): in the Agile methodology adopted by FI-WARE, EPICs mean 'work to be done' (see also my yesterday's mail). I wouldn't propose to use them as basis for the creation of Use case diagrams. I would rather start from the 'Product vision', i.e. the High Level Description of our GEs to create such diagrams.

Any further input by other partners to this discussion is of course welcome!

BR
Pier

Oggetto: Proposal for specification conventions (I2ND49)

Dear I2ND partners,

as decided during our last conf call, we have to make a joint proposal for the conventions to be adopted for FIWARE specifications (action point I2ND49).
Please find here https://forge.fi-ware.eu/docman/view.php/10/452/I2ND+proposal+for+convention+to+be+used+for+specifications_v0.1.docx our proposal.
In brief, we propose to use the folowing 4 UML diagrams:
- Use case diagrams
- Component diagrams
- Sequence diagrams
- Class diagrams
In addition, we also propose the use of StarUML as a free tool to depict UML diagrams.

Comments and feedbacks are welcome so that we can finalize our proposal by next Friday (7 October) and then Pier can discuss it at project level.

Best regards
Marco
