Re: Xindice

[Darren Petrie]

We use and really like eXist.  Nice work being done with  XQuery and  
XUpdate.  Integrates great with Cocoon.

Thanks, Joerg.  So I read up on Xindice last night.  Are people using
Xindice for production sites yet, or is it still in alpha?
I know of people using XIndice in production. It is currently Beta,  
but
we might expect a formal release at some point in the next three-six
months or so (but don't quote me - my information is a bit out of  
date!)
There is also eXist, which has become extremely good over the last few
months, especially with regard to XQuery support.

I picked Cocoon as my platform in part because of the elegance and
simplicity of keeping content in xml files in a directory(s) where I
can see them, and so I can have ad hoc document structures without
having to be tied down to a RDBMS schema that can never match
    all the
content types I'll be publishing. So I think for simplicity's sake
here assume I have a directory with a thousand xml files of textual
content, say, news articles.

So any given portal object needs at some point to be able to
    query my
repository for a few titles that meet a few criteria. That's easy in
SQL of course -- but how do I do something like that in the
XML/Cocoon world?
Do I index? Do I scour through once and then cache for a few hours?
D o I have a separate procedural/Java process that creates
intermediate files that can be more rapidly transformed into
    headline
lists? I can imagine different general approaches, but I don't know
how to implement with the Cocoon toolset, and I'm sure I'm not the
first person to have this requirement.
    A hand-written solution using DirectoryGenerator might be to  
slow if
    there are really thousands of files. Though you can cache its  
output,
    every non-cached access would probably take many seconds.

    More appropriate seems to be the indexing using Lucene, but I
    don't how
    flexible it is with regard to your needs (latest 3, first  
sentence,
    etc.). And the more stuff you have to store the more I would tend
    to an
    XML database like XIndice.

    All components are delivered with a recent Cocoon.
