Marcos,

Every application can't be seen as a widget.

What's being sought here is a self describing resource that serves as a 
manifest. The resource in question would be format agnostic, its base 
schema would be fundamental i.e., in the form of eav/spo triples (or 
3-tuples) plus URIs in the e(s), a(p), and v(o) slots. URIs would be 
resolvable.

This about a resource that is endowed with the following:

1. profile descriptiveness of FOAF
2. RESTful interaction at the HTTP level
3. ditto but via HTML pages via Web Intents -- so delivering RESTful 
interaction patterns via HTML documents if user agents seek to operate 
that level instead of HTTP.

Of course, one representation of such resouce could be interpreted as a 
Widget, but that's one interpretation of a data payload, not the sole 
option.

Tim is oriented towards more abstraction than the specificity of a 
widget, methinks. This abstraction is ultimately a function of loosely 
coupling the following:

1. data model
2. data representation syntax
3. data serialization formats
4. data access protocols
5. data object identity.
