xml-dev - Software for indexing & querying XML

["Laurent Bossavit" <laurent@mmania.com>]

Hi,

I'd like to solicit pointers from XML-dev members to any software 
packages (free, open, commercial; for Unix, Windows, or other) with 
the following base capabilities :
* multi-user server software
* index entire collections of XML documents
* perform "complex" queries over the indexed collection (where 
"complex" implies a query language such as XQL or a reasonable 
facsimile thereof)

Please note that I'm *not* including in the set outlined above 
software such as eXcelon or Oracle 8i, which can perform XQL or 
structured searches on *individual* documents. (eXcelon does "cross-
document searches" but this relies on maintaining so-called "binder 
documents" - this is not a viable option for the particular project 
I'm evaluating).

I'm currently aware of the following packages; please help me 
complete this list if you know of any other that satisfies the above 
requirements.

XML Query Engine (http://www.fatdog.com)
Recently announced here, in-memory indexes with XQL queries, Java, 
commercial closed-source.

Xdex (http://www.xmlindex.com)
Persistent indexes, XQL and full-text queries, Windows NT, commercial 
closed-source.

TEXTMLServer (http://www.ixiasoft.com)
Persistent indexes, enhanced full-text queries, Windows NT, 
commercial closed-source.

Thanks in advance,
