We’ve been busy with new internal projects, as well as some milestones for some customer work:
First, we’re getting very close to putting an RDF-powered data integration app into production at NASA HQ. There have been Semantic Web projects at NASA, but not very many have been put into production alongside ordinay business apps. If we’re not the first (and we probably aren’t), we’re at least early.
At the Semantic Technology conference next week our customer, Andy Schain will be giving a talk about this app, which is called BIANCA, and another one, called POPS, we’ve been working on for NASA.
BIANCA provides a single, integrated view of information about, including relationships between, applications, servers, network services, networks, and change items for NASA HQ. The integration is over four different data sources, and with this integrated view we’re able to provide some novel analysis services, including the ability to do disaster and other outage planning scenarios based on building dependency graphs of the relationships between BIANCA nodes. From these graphs we can generate outage repair plans (though these are not yet optimal plans, that’s coming in the next version) as well as productivity estimates per hour of downtime.
BIANCA is a Pylons web app (and RESTful web service) in front of an RDF database. (The next version of BIANCA will include live querying of DNS, SNMP, IDS, and other “network fabric” services. I suspect we’ll do something in Sesame by building a new Sail for some of these data services.)
POPS (People Organizations Projects and Skills) is the other app, which will go into user pilot soon: it’s an expertise locator service for NASA civil servants and contractors (all 80,000 of them), which also integrates disparate data sources (this time 6 or 7 of them) using RDF. (For more details, check out the 2006 XTech talk about POPS.)
The interesting bit about POPS is the client user interface, called JSpace, which started off as our clone of mspace, but has since diverged in some non-trivial ways. JSpace translates user input into RDF queries against a data aggregation accessible via HTTP.
JSpace is an example of what the cool kids are calling these days a linked data browser, though we haven’t yet done a good enough job talking about it publicly, so no one really knows anything about it at all. One project for the summer is to get more demo data sets up on our site so people can play around with the webstart version of JSpace.
Second, our first internship program, which we’re calling 2007 Semantic Summer, is already an unexpected success. Honestly, I didn’t think we’d get a single applicant, since we’re new and the program is even newer. But we’ve gotten about 10 so far, several of them from very strong candidates, mostly people working on a PhD in computer science and pursuing a diss topic in Semantic Web.
We’ve accepted four applicants for the summer, and there’s another who may intern with us in the fall. This is all very exciting: they’ll be working on a range of projects, including new stuff for Pellet, the next version of BIANCA, and some of our internal projects.
Third, the 2007 OWLED (the OWL Experience and Directions) Workshop—which we’re proud to sponsor—is coming up very soon, the first week of June, right after ESWC in Innsbruck. I wish more of us were able to attend, but it’s not a cheap or easy trip from DC and we’re swamped with engaging work. We did get two papers accepted; they’ll be presented by our European R&D, i.e., Bijan.
We’ve very excited to see the registration numbers looking good, as well as a very cool program of talks and papers. If you’re into OWL DL, OWLED is the conference.
Finally, watch this space on or around 7 June: we’ll have a couple of announcements to coincide with OWLED which will be worth hearing, especially if you’re into OWL.
