I am going to be heading the OGSA-DAI development team that will start to work to add the global schema to local schema mapping functionality into OGSA-DAI. To ensure we meet your requirements it would be great if you could get some data to design and test with.

Would it be possible for you to send me:
- a description of your global schema
- for two or three of your datasets:
* the local schema
* a sample of the data (just enough rows to cover various cases and experiment with)
* DBMS type (SQLServer, MySQL, Access, excel spreadsheet, flat file etc)
* a description of how the global schema should be mapped to this local schema

We plan to have some initial design sessions on this work in the week commencing 26 November. If it is possible to have some data before this it would really allow us to focus on your requirements.

I hope I am not asking for too much. Please let me know if this will be possible.
