Assumptions

1. Everything is expressed as a SchemaOrg CreativeWork
2. A "Catalog DataSet" may consist of a single CreativeWork or have associative relationships (e.g. child, parent, sibling, etc.) with other CreativeWorks.
3. Any "valid" SchemaOrg representation is allowed
4. Datasets that contain multiple content items (e.g. HS resource) should consist of a higher-level dataset associated with content-level datasets.
