RE: [Wings] charting development
Keiron,
this could be of interest for the charting stuff needed for Forrest
(http://cvs.apache.org/viewcvs/xml-forrest/): we plan to provide
xml.apache.org visitors with number of downloads, commits, mails, etc...
preferably also in a graphical presentation. We have been trying to do
some direct XML2SVG using XSLT but that is painful at best.
Could your stuff be packaged as a Cocoon component? Is there some place
where we can take a look at it?
Bye,
</Steven>

It can be placed anywhere, but as for Community, I think that Cocoon
scratchpad or contrib is not the answer.
I had more commits on wings on krysalis than in Cocoon scratchpad for the
Cocoon Chart2Svg Transformer.

Wings is just a charting package.

Well, the primary goal of Wings is to become a charting package API.
Secondly of having an Apache license implementation.
I had a discussion with JChart main dev, and asked him to merge with
Krysalis.
He thinks that LGPL serves him better...
Anyway, we just had a volunteer on the krysalis list to make the Cocoon
Chart Transformer working.
Krysalis is a momentum builder, and it's starting to work.
We are constantly in the top 100 on sf, and 20 on the mailing list, growing
per 2-3 a day.
I think that it's a good opportunity for starting new projects, don't you
think?

Hm. I definitely have more control over what is being added to Forrest
;-)
We are working on some book.xml replacement and I will add that to
Forrest if no-one protests, too.
Seriously: if this stuff is useful for Forrest, maybe they will better
be taken care of within Forrest - I don't have too much time left to
explore Krysalis/Cocoon scratchpad/contrib areas.

Not that I know, but Nicola will sure answer that ;-)
Wings uses Centipede, but that's another issue.

Would it be better placed in the Cocoon project (third party if
necessary)? I know *I* could use it for some of the project's I'm
involved with...

come to that, does wing's plug into Cocoon or Krysalis/Centipede?

I don't know what licenses we can/can't use :( I think it's a shame
we can't all work together.
I'll take a look at the jfreechart, perhaps we could come up with a common
DTD/Schema for describing charts in XML? Thats what I wanted to do with
the code I contributed to Batik - start a development going, but nothing
caught :(
Anyway, thanks for the links,
J.

Keiron is proposing to contribute his own unnamed code to Wings, I
believe...
Wings itself is situated at
http://cvs.sourceforge.net/cgi-bin/viewcvs.cgi/krysalis/krysalis-wings/
currently, but doesn't offer any XML i/o as far as I understand. Having
an XML input to a charting package would be cool and alleviate some of
the Forrest burdens, I guess...
A friend mentioned http://www.object-refinery.com/jfreechart/, doesn't
have any XML input, too, plus it uses LGPL as a license...

This could *definately* be of interest, is there a web page/code
we could look at? I did a search of Google and sourceforge and,
although I know Keiron from the FOP development I've not found
any mention of wings (at least, nothing to do with Java Chart
development ;)
