xOperator, the Valuation Industry, XSLT, GRDDL and RDF

I just discovered the most amazing thing. It's a jabber/xmpp sparql interface, called xOperator.

It sits between you, the end user, and multiple other agents and datastores. It uses XMPP (Google talk!) to interact with you.

You say things like:

me: add ds DBPedia http://dbpedia.org/sparql

me: query SELECT ?name WHERE {
?musician skos:subject <http://dbpedia.org/resource/Category:Australian_musicians> .
?musician foaf:name ?name .
}

Big whoop you say.

Well, I've been working on both an XML_GRDDL package (php5), and the relevant GRDDL transformations to turn LIXI Valuation documents into the relevant RDF/XML representation.

I'm also re-deploying work's internal Jabber server in the not too distant future.

So:
1. We handle a pretty big chunk of all residential valuations within Australia.
2. A lot of that gets described adequately in LIXI
3. There's now or soon to be a GRDDL transformation or two for that
4. And a GRDDL parser for PHP
5. Add in xOperator
6. Add in robust jabber services
7. Mix in a few microformats as well

Viola:
My workplace is half a step away from becoming a knowledge enterprise as well as a valuation panel manager.

That's not bad for a few days off!

Imagine these future scenarios:

Working smarter with internal data and external clients:

Internal xOperator to answer questions like "show me similar valuations we've done to address xyz", and "show me everything valuer X has completed over $1million"

Paid commercial access to a SPARQL service as well, for larger clients who want to better understand the marketplace
Paid commercial access to an xOperator style service for smaller clients, who just want a couple of pre-built, on demand answers


Publishing old (> 12-24 months) LIXI data on the web
Merge our data up with other countries, like the US, for trend analysis
Provide anonymized public data, with http basic auth. to protect names, addresses, privacy
Merge diverse sets of data - ie, imagine EuroStat data for Australia, but with an atomic level of detail available about the raw input

Provide semi-automated valuations based on known data
Suburb X has a population of Y and an area of Z (db/wikipedia), factor that into calculations
