My view is just the reverse of yours: the non-media documentation is too simple, and has lots of gaps ;) Anyway, the media documentation actually started out of the tree, by the time Alan Cox were the V4L2 maintainer, as two separate documents. The first one written 1999 (v4l2) and the second one in 2001 (dvb). They were merged upstream by 2006 or 2007, after several conversions (the DVB doc were in LaTex, and the V4L2 one, were on a very old DocBook version). We're doing a real hard work to keep it updated over the last 10 years, and we just don't want to throw it away and do a fresh start. Whatever we do, we should not lost documentation nor lost the scripts that have been working so well to enforce the docs to keep updated as we touch on the code. > I think we'd be in a > better position now if all of that had been done in a more generic way > for all the DocBook docs.

Having the capability of integrating with other documents is a nice thing. However, the media uAPI book will have *very few* outside references (right now, I can think on just one reference, at the introduction that mentions the ALSA project - even so, maybe the best would be to point to the ALSA project website, but, if we decide to point to the internal ALSA docs, we could use intersphinx). The reason for that is simple: it describes the API from the Kernel to userspace, and not the Kernel's internal API. The Media Kernel's internal API is described at the media section of the device-drivers.xml. There, references to the other Kernel-doc documented APIs is very welcomed.
