import/export with meta-data

[Wouter de Vaal <wo...@hotmail.com>]

Hi,
 
I'm looking for a way to have a complete collection structure being exported
with keeping meta-data on XML documents and binaries in tact and which
I can import again afterwards. Is there functionality for this (as far as I
can see, xindice -export doesn't support this)? Does this need to be
written? If so, any suggestions how I should do this?
 
Regards,
Wouter de Vaal

With this wiki, it's easier to go the other way around: first, go to 
page you want to create:
    http://wiki.apache.org/xindice/XindiceFAQ/XindiceMetaExport

And you'll see "create this page" on top of the page. Once you have the 
page created, you can go to XindiceFAQ page and edit link.

I've created the page for you, you can just add content :-)

Thanks,
Vadim

Ok, better late than never. I'm a newbie at Wiki's so could you please help
me out.
I've got to the FAQ page on the wiki and edited it and created another link
like
 * [wiki:XindiceFAQ/XindiceMeta How do I import/export metadata?]

from the helpfile I guessed that would create a new page that I could edit,
but it just creates a link to some other page and the hover says
"BadWikiTag".

So what's wrong? The page I try to edit:

http://wiki.apache.org/xindice/XindiceFAQ

Thanx, I totally missed the meta collection. *doh*.

For details on external meta data, see:
    
xml-xindice\java\src\org\apache\xindice\client\xmldb\services\MetaService.java
    xml-xindice\java\src\org\apache\xindice\core\meta\MetaData.java
And config.xml:
      -   use-metadata:
      -       When set to 'on', enables external metadata facilities
      -       for this database instance.
And also see guide-developer.xml, it describes external meta data.


For details on internal meta data, see:
    xml-xindice\java\src\org\apache\xindice\core\meta\inline
    
xml-xindice\java\tests\src\org\apache\xindice\integration\client\resources\BinaryResourceTest.java

Internal meta data used to store some information beside the data, such 
as xml/binary flag and creation/modification dates. External meta data 
is accessible programmatically and can be used in applications.

This exports meta data for test collection:

    bin\xindice export -c /db/meta/Metas/test -f output-dir

I can find the export command, but I can't see how it supports metadata,
could
you give me some pointers where to look? I've looked in CVS at
org.apache.xindice.tools.command.ImportTree/ExportTree, but didn't see
anything
of the kind..

If needed, I'm certainly willing to do my bit.

Do you mean "inline metadata" or "external metadata facilities"? You can 
export external metadata using "-export" command, it is stored under 
system collection.

For external metadata, I guess the only thing needed is improvement in 
documentation on import/export. For inline metadata, it should be 
possible to modify export command to store it in separate file beside 
resource files. Send patches to the dev list for discussion and applying 
to CVS.
