fcrepo-transform allows you to set up and publish transformations of the RDF that composes a Fedora object's representation. You can use SPARQL for RDF-to-RDF transformations, or LDPath for RDF-to-named-fields transformations.
Example uses might include:
- Presenting different views of an object's metadata to different audiences
- Live-translating from one kind of metadata to another
- Filling in the fields of an HTML form for editing metadata
