Arguments for a
schema transformations project
• Abstractness
• Reusability
• Levels of interoperability
Our proposed solution
• Use published or existing metadata schemas.
• The transformations are encoded in XML and
XSLT.
• Intake functions let third parties contribute
schemas and mappings.

A schema crosswalk repository:
What it solves
• Enforces a standard encoding format.
• Permits a one-stop service for data conversion.
• Encourages re-usability.
• Facilitates the discovery of a common
semantic core.
• Permits inferences about metadata formats.
