2. Gap: Data integration can involve some [usually undocumented] information loss

Solutions: Data collectors and providers need future data integration in their plans Integration preparation steps need to be well documented (new metadata) Quality information needs to be carried along integration process (old metadata)

3. Gap: Documentation
Documentation needs to include clear descriptions of transform/integration limitations (fitness for use)
Metadata standards need to include mechanisms for integrating that information into tools
Tools need capability to capture lineage information automatically. How does that information get into the citations? Is there a role for the archive?
Tools might provide warnings…?
Users need to understand limitations/caveats of transformation operations.
