[Moims-dai] OAIS-IF UML diagrams for getting enough RepInfo

[david at giaretta.org]

Dear all

 

We discussed the OAIS-IF last week and I proposed a supplement to Steve's
work.

In particular I have worried about how we show how the various messages are
"understood" by the receiver, and if a message is not understood immediately
then how further Representation Information may be requested.

 

I've added some UML diagrams in the Google doc I prepared - see
https://docs.google.com/document/d/14V0wN6nEnG2MaSMmNClRzuDrTxcB0zjv0XNw2pdY
DI8/edit?usp=sharing

 

I hope this shows what I meant in the discussion last week.

 

I have not quite made it completely consistent with the CCSDS Message
Abstraction Layer (see https://public.ccsds.org/Pubs/521x0b2e1.pdf ), but if
this seems a good way to go it may be relatively straightforward to do that.
We then also be able to use the MAL JAVA API (see
https://public.ccsds.org/Pubs/523x1m1.pdf ). A JAVA prototype implementation
could be quite straightforward.

The binding to the MAL HTTP Transport (see
https://public.ccsds.org/Pubs/524x3b1.pdf ) may also be useful. 

 

Regards

 

..David
