In the distributed domain contributions and any updates have to be provisioned to each node. There are many ways of doing this, ftp, http, shred file system , etc. to the extent that Tuscany shouldn't really care too much about how it is achieved. I would expect that at any give time a domain at a node can be notified of its configuration given the URL(s) of where to find its up to date contributions. For example, in the stand alone case this could just resolve to the contributions in "file:///path to sca-cntributions dir".
However I'm a little unclear how to deal with configuration updates. There have been a number of posts recently about incremental updates to domains [1] and [2]. I can see that contributions can be added and removed but the implication of the discussion in [1] and the assembly spec (1.10.4.1) implies that contributions can also be updated. Is there code to support this in place already? I'm assuming the current approach is to drop the current contribution and load the updated version rather than deal with deltas.
