RE: standardized Maven GAV URN?

[Stan Devitt <sd...@rim.com>]

Such a notation would be much more useful if it were 

	1. standardized and 
	2. unambiguous 

My personal preference would be "something like"    

	groupId:artifactId(classifier):version;extension[scope]

This way, the classifier, the extension, and the scope could be optional simplifying this to

	groupId:artifactId:version    (defaulting to no classifier, extension=jar, scope=compile)

Examples:

	junit:junit:3.8.1
	junit:junit():3.8.1
	junit:junit:3.8.1;jar
	junit:junit:3.8.1;[compile]
	junit:junit:3.8.1;jar[compile]
	junit:junit():3.8.1;jar[compile] 

Whatever is done, having multiple conflicting ambiguous versions of this is just bad design.  The final choice should probably be consistent with the URI specification http://labs.apache.org/webarch/uri/rfc/rfc3986.html   (in this case, a path with scheme=GAV, a blank authority, and no query or fragment)  .  It should be registered.

	i.e., GAV:junit:junit:3.8.1

PS.  The full set of coordinates falls into two categories:

	1. name the artifact  (group,artifact,version,classifier)
	2. meta-data about the artifact 
		- assistance to help find it in a repo  (extension)  
		- restrict its use  (scope)

Here, I have deliberately separated (1) from (2) by a ";"
