Paggr article in Nodalities Magazine 6

The latest NodMag issue features an article about Paggr.
Talis' new Nodalities Mag is now available online (and the print version is on its way to subscribers). This issue contains six semantic web articles, including one about Paggr:
  • Linking Data and Semantics at O'Reilly - Gavin Carothers and Charles Greer tell O'Reilly Media's Linked Data story.
  • Discovering SPARQL - Alex Tucker exposes SPARQL endpoints via Bonjour.
  • Linked Data In(ter)Action - Benjamin Nowack discusses Paggr.
  • Introducing: STI International
  • Social Semantic Web Scales in the Cloud - Simon Schenk discusses SemaPlorer
  • Streams, Pools and Reservoirs - Leigh Dodds explores flowing data

Paggr screencast: Linked Data Widget Builder

A screencast about Paggr's sparqlet builder.
Running an R&D-heavy agency in the current economical climate is pretty tough, but there are also a couple of new opportunities for these semantic solutions that help reduce costs and do things more efficiently. I'm finally starting to get project requests that include some form of compensation. Not much yet (all budgets seem to be very tight these days), but it's a start, and together with support from Susanne, I could now continue working on Paggr, semsol's Netvibes-like dashboard system for the growing web of Linked Data.

An article about Paggr will be in the next Nodalities Magazine, and the ESWC2009 technologies team is considering a custom system for attendees which is a great chance to maybe get other conference organizers interested. (I see much potential in a white-label offering, but a more mainstream-ish version for Web 2.0 data is still on my mind. Just have to focus on getting self-sustained first.)

Below is a short screencast that demonstrates a first version of the sparqlet (= semantic widget) builder. I've de-coupled sparqlet-serving from the dashboard system, so that I'll be able to open-source the infrastructure parts of Paggr more easily. Another change from the October prototype is the theme-ability of both dashboards and widget servers. Lots of sun, sky, and sea for ESWC ;-)

The Linked Data Value Spiral

The value of Linked Data grows when it's utilized an re-distributed
I'm currently writing an article about paggr for the Nodalities Magazine. As there is not too much to write about yet, I'm focusing on the basic idea (customizable Linked Data dashboards), its inspiration (TimBL's RDF Clipboard concept), enabling technologies and trends (Live Clipboard, widgets, AJAX homepages, sub-page-level interaction), and the user interface challenges related to generic interaction with Linked Data.

One thing that I thought might be worth sharing separately is the "Linked Data Value Spiral" below. It tries to illustrate that semantic data don't have a single-loop life cycle, but that re-distributing utilized ( = newly meshed/combined) information will create a self-enforcing "Linked Data ecosystem". I tried to associate the individual value creation processes with SemWeb market sectors. (RDF stores, for example, are typical information organization products, paggr tries to remove the bottleneck between utilization and re-distribution, etc.)

Linked Data Value Spiral

It's just an abstraction, the boundaries are of course blurry (a SPARQL endpoint can help with both utilization and discovery), but I still find the simple spiral and its segments handy to classify current products and companies. It even helped me a little to identify market opportunities and gaps:
  • The recent VoiD effort could have a significant impact on the whole Semantic Web progress.
  • Entity extraction providers like Zemanta and OpenCalais could play a huge role to boost creation processes.
  • What about "accelerator" products that offer a shortcut between utilization and creation (i.e. apps that create Linked Data while you are using them, with instant re-distribution)?
  • Is it a problem when a service like Freebase exports RDF but doesn't provide links to external datasets?
  • ...

Feel free to use and share.
