Using and querying custom property sets/items
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 athttp://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.

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
