Subject Re: Avoid indexing of old UIMA documentation
Date Thu, 07 Apr 2016 20:36:56 GMT

This sounds like a good idea to me :-)

There's one small issue possibly, to changing the folder structure.  The DOCBOOK
schemes have some fancy way to link between docbooks; these require that the
books be kept relative to one another in some file tree structure.  As long as
that's not changed, I think there will be no problem. 

If anyone's curious, the relevant bits of config info are in the
uima-docbook-olink project, in the various "site.xml" files.  You can see refs
to the famous "d" folder there.  There may be a dependency on the "books" being
just one directory layer under d/, so putting an extra layer might break things
(but I'm not sure...).

Maybe there's a way to do this without introducing a new level in the directory?
