[Fiware-wpa] FIWARE: FMC Block diagrams: Reference_Sheet-Block_Diagram.pdf (application/pdf Object)

[Bisztray, Denes (NSN - HU/Budapest)]

Dear Thorsten,

 

I agree with most of your points, lots of people doing it wrong. However, as far as I understood from the link you just provided the R with small arrow simply indicates the direction of the request-response communication, no RPC is mentioned anywhere. Quoting the pdf "Agent A1 can request information from agent A2 which in turn

responds (e.g. function calls or http request/responses)".

 

Best,

Dénes

Dear Open Specification Writers,

 

while having a quick look at different Open Specifications in the private Wiki I noticed that there is some confusion according to the meaning FMC block diagrams.

 

Please have a look at this cheat sheet. The semantics is actually very simple. However, it would be nice if we can use it consistently across the different Specs.

 

So for example:

 

*	The dotted rounded rectangle means: structure variance (parts of the diagram can be there multiple times, sometimes controlled by an agent.)
*	If you want to subsume parts of the diagram you should us a plain border box (maybe with a light grey background)
*	The R with a small arrow means an RPC-like semantics of a channel between two components (agents)
*	Two components can only be connected via a channel. (no direct lines between them)
*	A component (agent) can read/write from/to a storage (without a channel in between)

 

 

Best regards,

 

Torsten
