Metadata [Was:RE: [PATCH] XTools adds user.dir to absolute paths]

["Viner, David" <dv...@yahoo-inc.com>]

let me know if my cut at metadata does not support what you need.  i'm happy
to modify it or revamp it to fit the needs of the community.

last modified time is there.  i only use it for documents, and haven't
completely tested it, but it works for me (in my application).  let me know
if it doesn't make sense.

David did a first cut at an implementation, have you seen it? However, 
metadata are my pet peeve too: the problem is that it's an issue to be 
solved in two places: here and on the XMLDB API list.

This is a recurring issue. Please have a look at these threads:

It does support what I need. I need to expose it via some API though. 
I'm thinking about adding MetaService - is there better way to do it?

I did not understand how it gets stored into/retrieved from the 
database. Everytime I ask for metadata I get current time. I think the 
problem is that the retreiving part of code is commented out (see lines 
633 - 640):

  
http://cvs.apache.org/viewcvs.cgi/xml-xindice/java/src/org/apache/xindice/core/Collection.java?annotate=1.22

And instead, current time is taken every time you get meta. How does it 
work for you?
