Hi Giuseppe, that is a good new! and you are welcome.
You can contribute initially by writing patches (see ), that is the most common way for an initial contribution. IIUC, you are ready to help on index implementation (: REC 1.1 § 6.10). I don't know if somebody in the dev team have some thought about this, so the question is open and should be asked on Fop dev list. I see nothing about indexes neither in Fop site nor Fop Wiki. I guess that indexes implementation should act in multiple parts: properties, areas tree, layout, but there are some gurus that can give a more precise answer. So, Giusseppe I suggest to continue this discussion on FOP dev.  http://xmlgraphics.apache.org/fop/dev/index.html#patches  http://www.w3.org/TR/xsl11/#d0e13293 Pascal Le 18/06/2010 11:26, Giuseppe Briotti a écrit : > Well, I can partecipate to FOP community trying to implement such > feature, but I don't know if I have the basic knowledge to do that: > I'm experienced developer in Java, C# and C/C++ thus probably I have > the "developing knowledge" but I don't know much about the FOP > implementation itself... can you suggest a starting point? >
