Using and querying custom property sets/items Sean McLeod 10-02-2005

Hi

In terms of the Windows Indexing Service and IFilters you can register
custom property sets and return data for these custom properties when your
IFilter is called.

In the MSN-DS (WDS) dev guide at http://addins.msn.com/devguide.aspx they
mention that your IFilter should return values for all properties that it
finds for the item types it indexes.

However the docs go on to state that :

For a complete list of supported properties used by Desktop Search, see:
C:\program files\MSN Toolbar
Suite\DS\<VERSION>\en-us\Data\Config\msscolmn.txt
Which is a fixed subset that won't know anything about custom property sets
that have been registered.

Is it possible to add support for custom property sets by editing schema.txt
in the above listed directory? Or is the list fixed at compile time?

The reason I ask is because I would like to be able to use property sets
like these returned by PixVue for XMP/IPTC data embedded in images.

http://www.pixvue.com/help/search.html

So for example I'd like to be able to issue a query along the lines of:

headline:"Shuttle Launch"

If there is no way to make use of custom property sets today are there any
plans to add such support in an upcoming version of MSN-DS (WDS)? Or do I
need to resort to using the Windows Indexing Service and/or wait for Windows
Vista?

Cheers

I'm sorry to say that I don't have answers for you, but there are a few
Microsoft Dev/Suport people that drop into this newsgroup from time to time. You
might still get an answer from one of them.

Yep, although I wish they were a bit more proactive in answering questions
posted here. I'd also like to see a separate developer specific group and
end user group.

Maybe after the recent release of their enterprise version of WDS they'll
have more spare time to answer questions here ;-)

Cheers
