Re: Impact on KDOM2
by Frans Englich on Thursday 13/Jul/2006, @08:39

Some more comments:

* No, Patternist doesn't use KDOM's tree implementation. KDOM has an implementation of W3C's DOM XPath Module. That is, the implementation acts as glue code adapting Patternist's APIs into the DOM API(which is a very limited subset compared to Patternist's). So, KDOM depends on Patternist in order to supply the XPath DOM API.

* No KDOM2 exists. KDOM, kdenonbeta/kdom, exists, which originally was derived from KHTML during KDE 3.x(kdelibs/khtml). Nikolas Zimmermann(one of the main hackers on KDOM) have said he consider KDOM dead because work is taking place elsewhere. However, KDOM contains tons of code that can be integrated elsewhere(such as XPointer, OASIS XML Catalog 1.1, XInclude 1.0 and DOM 3 Core implementations).

* KSVG2 is the rewrite of "KSVG". KSVG is the one used in KDE 3.x, in kdegraphics. KSVG is not relevant in these discussions.

* KSVG2 is(or was) being integrated into kdelibs/khtml in branches/work/khtml-svg(by Nikolas and Rob). However, it's been a while since that was active so perhaps it will start all over now with Unity and that general KHTML development has proceeded.

* The project called "KHTML2", kdenonbeta/khtml2, is pretty much dead as far as I know. It was an effort to put KHTML on top of KDOM. Carewolf(Allen, the CSS hacker) have expressed it's no way that's going into kdelibs. It's also in general rather old and obsolete and not into the loop of recent developments.

* When Apple was in the early stages of opening up their repository and acquiring SVG support by using KSVG2, they ported needed parts from KDOM into Webkit(IIRC) and the two bases were mutually synced for some time at the beginning. But KDOM as a whole is not in Webkit. However, the code bases are quite similar in this area so KSVG2 operates directly on top of Webkit.

All this is very confusing as one can tell, and I many times think it's rather unproductive because of all the projects in action where little synchronization and planning is taking place. In several cases decisions have been made which has down right hurt other projects.

And of course, I can be wrong above or have missed something, it's not easy to track all this :)
