Am I correct that your extractor only pulls out properties, or am I confused?
Also, it looks like you used the low-level API, so will this work with any office document?

Hi,
sorry for that ;-)
This extractor is very basic. It uses the jakarta poi library to access the office files.
You can map the extractor to files matching a url (e.g. all files under /files/word/) or matching a content type (application/ms-...)
When content is stored the extractor extracts some properties from the given stream and stores them as webdav properties.
You can afterwords use DASL to search documents by using this properties.
We didn't figured out how to get speaking property names out of the documents, so you can configure the property names in the Domain.xml.
Have a look at the Domain.xml, you can see that a cryptic DocumentSummaryInformation-x-y is mapped to webdav properties.
It would be really helpful if you could have a closer look at the poi library and check out if there is some more useful information stored in the office documents.
Regards,
Daniel
BTW: Many thanks go to Jan St�vesand (a collegue of mine) who figured out the POI things and will hopefully join the slide community soon...

Can you give me an idea of what this Extractor does, and what might be missing Daniel?
