Can you provide an example of a URI which can't be parsed?

*repository-uri = access-specifier / product-specifier /
version-specifier / artifact-specifier*
It defines *access-specifier* and *product-specifier*, but leaves
*version-specifier* and *artifact-specifier* opaque, to be defined
by language, platform, or artifact-specific best practices.
Since version-specifier and artifact-specifier are opaque, there is
no way to tell where product specifier ends.
I know we have suggested version, and a Java artifact specifier.
But what about other languages, Like the new cool O/S language foo.
It's artifact's are called bars
http://repo.com/org/foo/cat/dog/bars/bar.zip
What is the product org.foo.cat or org .foo?
Is cat the version name or is dog.?
Perhaps there are two kings of bars, one for dogs and one for eggs.
or what ever.
If product-specifier is opaque, and the artifact URI
doesn't meet the criteria specified by one or more of the proposals,
then a tool can't look at its URI to determine what the product or
version is.
Does that really matter though? How can a tool sensibly interrogate
an artifact it doesn't understand?
organization/project is a workable solution that lets a tool make
intelligent guesses based on URI only,.
I like the simplicity of
Top level = Organization that distribute things
2nd level = A project. (a sub organizational unit that
distributes artifacts)
3/4 level = Version, (interim builds take an extra level
4/5 = Artifacts stored any what a project likes. (with best
practices for Java and other languages.)
The ONLY limits we have on organization and project and version is
it must be valid URI character and it can not be a / (ie pchar)
I'm not really fussed if product-specifer is opaque or not -
I'll go with the concensus view.
IMO, the repository layout is cleaner if it is opaque, and tools
can still parse any URI which meet the criteria of the proposals.
If product-specifier is restricted to 2 path segments, then
tools can parse any URI, but the repository structure is flatter,
and can't represent project heirarchies.
