Story (A paragraph or two describing what happens)

My institution has developed a web application which provides a nifty visualization (html + js) for certain kinds of Fedora objects, as well as an XML representation of the same. To create the vizualization, my application reads a fedora object, queries a few indexes, does a few computations, and renders an appropriate representation based on the desired content-type. I would like to expose this web service at a URI /rest/path/to/object/viz:nifty for any object /path/to/object with an rdf:type of viz:Visualizable. I'd ideally like to wire my application to the viz:nifty URIs by creating or editing some sort of configuration file or fedora object, rather than compiling and deploying specialized code to do that.

API Extension Architecture's role:

  • Allow repository manager to bind path segment viz:nifty to objects with rdf:type of viz:Visualizable
  • Allow the repository manager to specify the address of the web service that implements viz:nifty
  • Route user's http requests from viz:nifty to the web service, and return its response
  • Provide the identity of the relevant Fedora object to the web service when routing http request to it.

Web application's role:

  • Respond to requests directed from viz:nifty

Repository manager's role:

  • Deploy web application
  • Specify address of web application, rdf:type of relevant objects, and URI path segement (viz:nifty)

Fedora's role:

  • Respond to requests from the web application, if any.
