  1. Looking into the future… Providing Social Science Data Services Jim Jacobs

  2. First principles • Metadata are data about data -- information about information. • It’s all about having complete, accurate, re-usable metadata. • Software to process the metadata is secondary. We should be able to have metadata today that we know will be usable in unforeseeable computing environments (operating systems, software, hardware).

  3. First principles Metadata should be… • Comprehensive • Complete • Uncompromised • Consistent • Flexible • Sharable • Usable and re-usable • Preservable • Parseable by computer • Documented • Non-proprietary

  4. How XML fits in… • XML is designed to be parseable with generic tools. • XML can encode meaning and can be self-documenting • XML is non-proprietary, open, flexible.

  5. How XML fits in… XML is designed to make it easy to find and usejust the elements you need from a large document. “Cherry picking”
