rapid prototyping

Dear members of the Semantic Web & Views development,

I have been playing with the idea of using Drupal as rapid development environment for (semantic) web applications, rather than CMS. The idea is not as far-fetched as it may seem at first:

CCK allows me to define a database model. Core functionality in D7.

Feeds parser lets me to pre-fill the data in nodes defined in step 1 - including the possibility to fetch data at regular intervals, update nodes and drop old nodes.

RDF-related functionality allows me to associate the data saved in pre-defined nodes with ontology terms.

Views allow mixing of data from different node types

It is also possible to programatically define data (e.g. automatically fill in a field) both in the node and in the View

Finally, there are plenty of modules that let me do just about anything with the data once I have it in nodes & views. Some exampels include e.g. visualization on a map, and setting up a web server (SOAP, REST, ...) that exposes my data to the outside world.
