Well, it's a long way from finished, but I have been working on a POWDER 
Processor in the last couple of weeks and there's enough working to show 
the general idea (I hope) [1].

Done so far:

1. Given a URI to describe, and the URI of a POWDER doc as a data 
source, it will use the latter to describe the former if it can. It 
understands IRI sets and ordered lists.

2. It shows you what RDF would be returned rather (on the Web page) 
rather than actually returning RDF at the moment.

3. If no data source is provided, it uses all the data in its database.

4. The UI includes a selector box for each of the examples in the DR doc 
for simplicity of demonstration but you can create your own examples if 
you want to.

I've included a To Do list on the page and, if I can. I'll do more on it 
before the event on Tuesday but I need to concentrate on things like the 
day job and working out a presentation between now and then so I doubt 
I'll have time.

It uses the validator [2] and a streamlined version of the group tester 
[3] as components. Eventually, these will all be combined into a unified 
tool kit (that's the plan any way).

As a final note - at the last F2F we discussed whether we will support 
'arbitrary RDF' in POWDER. This was translated into a Feature at Risk in 
the Formal Doc. Will we allow the creator info to be included directly 
in the POWDER doc or insist that it's held externally? Should we only 
allow simple predicates and objects in the descriptor sets? It was 
Charles that pointed out that these simplification steps will make 
implementation *a lot* easier. The tools I'm working on here all make 
the assumption that we will indeed decide to keep it simple. If the WG 
resolves otherwise, I have even more work to do...
