Subject: Re: [sca-assembly] ISSUE 8 - Artifact resolution - proposal V5
I'm finding that wording this resolution is very difficult. I think this
is an improvement.
I have a couple of reactions to the updates:
1) I would prefer to talk about the SCA artifact resolution mechanism in
general rather than specific to namespace import/export. While it's true
that the assembly spec only defines importing/exporting namespaces, it
needs to set the rules for how this mechanism works in general to get some
consistency across the specs. I don't want to allow the namespace
specificity in the words to be used by any language binding TC as a license
to do something completely different when they define their language
specific extensions. Line 3125-3132 should be in their own section of the
document (or merged into section 11.2.2) as they are specific to namespace
import/export.
2) line 3136 - import statements don't necessarily identify locations.
They have to be resolved before a location is known. I suppose we should
insert a paragraph about import resolution. You came close to doing that in
3129-3132. For example, we need to say that if there are two contributions
which both export the same thing, what happens?
3) Did not follow the example you added, and in fact if I read it correctly
is an alteration of the design. You might be hinting at what OSGI calls
split package semantics, but I'm not sure.
4) You're re-word of my example is good.
I'll note that the text does not yet deal with circular dependencies and
split packages. I was hoping to get a split package use case from Anish to
help us flesh this out some more.

Re: [sca-assembly] ISSUE 8 -
Artifact resolution - proposal V5
Dave,
Great stuff.
I've done an update to try to clarify some of the language which I found a
bit hard to parse. There is no attempt to change the
meaning of the proposal, so if it doesn't read right now, I've screwed up:
Word & PDF formats for those who have trouble with Word alone - fully
change marked.
Yours, Mike.

Subject: [sca-assembly] ISSUE 8 - Artifact resolution - proposal V4
Here is the latest proposal for Issue 8. It includes the updated words
from Mike E in section 6.6.
While I haven't received the use cases from Anish (AI 2008-07-22-3), I took
a shot at rewording the body of the changes in 11.2.1 anyway.
This closes my AI 2008-07-22-4.
