It would be great if people could copy and paste content schemas with RDF mappings from one site to another.

For example, University XX has a Node type Publication on their site that models an academic publication. Prof. Y could then copy the content type definition in JSON from the site and add it as a SPARQL Views resource to her site. Then she could use SPARQL Views to query for all of her publications on the main site just by adding her name as a filter.
