Re: [ee4j-pmc] Project/Specification dependencies 
Hi Wayne,

I think of the "consumes" relationship as meaning "consumes an implementation". 

So... EclipseLink /implements/ the JPA specification
and it also implements JAXB specification (JAXB-RI is the reference impl, MOXy, which is part of EclipseLink, is an alternative impl). Also note that MOXy has (unfortunately) direct dependency on JAXB-RI due to extending 'xjc' command. 

You may want to capture this relationship...
One note to Metro stack - from the very top-level point of view WSIT is build on top of JAXWS-RI which is build on top of JAXB-RI. JAXWS-RI can use MOXy instead of JAXB-RI. 

thanks,

 and Eclipse
GlassFish consumes EclipseLink. I believe that Eclipse GlassFish /implements/ some specs itself (EJB?) and /consumes/ implementations provided by others. Assuming this relationship is correct, Eclipse GlassFish has no direct relationship with JPA (though I could argue this either way; this is very much a choice between creating a meaningful chart and one that's overly pedantic).
The relationships from Eclipse GlassFish, I believe, are actually the most interesting ones.
If anything, we can eliminate the references implementation from the Jakarta EE Platform project as it references everything, and so isn't all that interesting on this chart.
FWIW, it's pretty simple to just eliminate that project and references from the dot file and render the chart without it: 

grep -v jakartaee relationships.dot | dot -Tsvg > ~/chart.svg

Does this make sense?

    This is pretty cool!  Thanks, Wayne!

    There's a bunch of stuff missing.  I'm working on a pull request...

    Also, Eclipse GlassFish consumes everything here.  Do you really
    want all those lines?  Or did you have in mind some more limited
    relationship for the "consumes" lines?

    I've been experimenting with using a graph to understand the
    relationships between the projects, I started capturing the
    relationships between the EE4J projects and specifications and
    came up with the attached image.

    The process of building this was a useful exercise for me to get a
    little more familiar with the projects.

    It's incomplete. Specs, projects, and relationships are missing.
    I'm presenting this here as a proof of concept.

    Dotted boxes represent specifications. Round rectangle nodes are
    projects that maintain the specifications (e.g /Eclipse Project
    for Stable Jakarta EE Specifications/ "maintains" a bunch of
    different specifications). Round rectangle nodes with thick lines
    are are projects that implement specifications (or otherwise
    implement stuff, like /Eclipse Grizzly/).

    This may be better represented as UML, but I decided to go with a
    simple digraph for now.

    I'm using Graphviz/dot, and have done nothing to try and influence
    the layout.

    I may be trying to accomplish too much with a single diagram.

    It may be more useful to capture these relationships with some
    kind of more general metadata. I decided to just use Graphviz
    notation to capture the relationships for now since I could do so
    quickly. We can maybe convert this to a different format later if
    we decide that it makes sense.

    Does this (or something like this) seem useful?

    If it seems useful, I'll put the dot file into our repository so
    that I can accept pull requests :-)
