I was looking for more ways to make use of lenya and other ways in which people have used it.
What I want to know is, does anyone here use Lenya with an XML database. If so, which one, and can you give some clues (without compromising security and NDAs etc etc) as to how you do it.


we once made an integration with XIndice and it worked very fine, whereas
the documents were kept parallel (within the filesystem and XIndice) and
XIndice was used to do XPath queries.

I hope this situation will improve with the integration of JCR, whereas
I am not sure if there is an existing persistance manager for something like XIndice.

For XML Database, my options seem to be :

    Xindice:  - been at 1.0 since forever (scary) / + it's an apache
    project
    eXist [http://www.exist-db.org/] : - I see no mention of XPath
    only XQuery / + LGPL, active development
    Sleeycat Berkely DB XML
    [http://www.sleepycat.com/products/xml.shtml] : - cost money.
    dbXML (revised edition)
    [http://sourceforge.net/projects/dbxml-core/] : - last release Aug
    2004. / + GPL


I found a post in the lenya-dev list with a link to a blog entry entitled :


*"Inspirationtional Technology: dbXML Open Source.... again" *[http://www.xmldatabases.org/WK/blog/579?t=item].

It describes the evolution of dbXML to become Xindice [http://xml.apache.org/xindice], dbXML stopped to facilitate the growth of Xindice only to be forked again to become dbXML. Again.

The reason for the re-release, from [http://tbradford.blogspot.com/2003_10_09_tbradford_archive.html#106572747255126845] :

    /For a period of time, he and I continued to contribute to the
    open source project, hoping that others would follow our lead and
    help to take Xindice in new and more organic directions. This
    never really seemed to happen, and the project is now, for the
    most part, stagnant./

>From the first blog post something similar regarding Xindice :

    /...Xindice hasn't fared too well of late and the project is
    pretty stagnant at this point. The project has been struggling to
    get a 1.1 release out. 1.1 was originally intended to be a quick
    bugfix release to go out a month or so after 1.0. Obviously it's
    been a fair bit more then a month/

the scary part is that both blog articles are from October 2003 and Xindice is still at version 1.0. Is it really _that_ "stable" or has it really gone stagnant?
