Re: [office-metadata] existing fields

[Elias Torres <eliast@us.ibm.com>]

Although I don't want to exclude existing metadata fields I would like to
remind us that it's not easy to do both a flexible and specific approach at
the same time. Let me clarify.

I believe there's a requirement that asks for asymmetric metadata. At the
very least we need to strip out all metadata from a document. If we use
only the specific attributes, then we can easily do that with an XSLT.
However, if we start using custom metadata attributes we run into problems
of maintenance of such transformations.

If we were to start with a fixed list of attributes, we can make special
cases for them, but I can see it getting ugly and not staying fixed.

For example, we can say that:

 <text:p meta:about="event1">
   The party will start at <text:time
 text:time-value="15:05Z">5 past 3</text:date> on <text:date
 text:date-value="2006-12-12">saturday</text:date> at <text:span
 meta:property="location">my house.</text:span>
 </text:p>

tranforms into:

 <text:p meta:about="event1">
   The party will start at <text:time
 property="text:time-value" content="15:05Z">5 past 3</text:date> on
<text:date
 property="text:date-value" content="2006-12-12">saturday</text:date> at
<text:span
 meta:property="location">my house.</text:span>
 </text:p>

That's what I'm thinking when I mean support specific attributes, any more
than that I don't have a solution to deal with any random number of
metadata attributes and specific ones in a genreal way.
