Sounds good - I'd change that to 

jigsaw.moduleinfo.id = org.openjdk.jigsaw.test.hello @ 1.0

as that's a string representation of the id (more then a name ;).

There can be multiple (or no) required dependences for a module, so we need a
way to represent a set of them. Same holds for provides and permits.

One way to do it is to introduce a new 'assignment' for
each member of such set, as done in the previous example.

On the other hand, we can (of course! ;) represent a set using a single line, 
instead - we just need to introduce a delimiter character, for example ",". 
So the prior example changes to

jigsaw.moduleinfo.requires = jdk.base @ 7-ea , something.else @ 0.4 

Would that work better for your needs?

Yes. See http://cr.openjdk.java.net/~mr/jigsaw/api/org/openjdk/jigsaw/JigsawVersionQuery.html
and the code at http://hg.openjdk.java.net/jigsaw/jigsaw/jdk/file/dc6e9e87b14a/src/share/classes/org/openjdk/jigsaw/JigsawVersionQuery.java

The syntax would be

jigsaw.moduleinfo.requires = some.module @ >= 0.1 , something.else @ < 1.0.0.0.0.1-b17
