Today I decided to set up an instance of the Pinetree system to better demonstrate how it works. We still are thinking about how to implement moderation for CRUD operations in Pinetree, which is why this particular instance of the system is read-only (i.e. it is only possible to perform GET requests). As the API of the system is published it should not be too hard to get the idea of how other types of operation works. Please note that the system is not professionally hosted in any way so do not expect it to be accessible 24/7. 
Enough rambling from my side; the demonstration of the Pinetree system can be found here. Now I need to get back to teaching obligations, oh the joy!

New design, new content

A new day and a new design to the site, pretty neat huh? I decided to change to an already existing WordPress template as there are people out there who knows how to develop them properly. Besides the new design I have added information about a system we have been developing at CeLeKT called Pinetree, which is a content repository based on Linked Data. While it is not yet available for download we are discussing to either put it up as open source or provide a binary file somewhere on the Web. The system itself still lacks authorisation and authentication mechanisms as we are still thinking about how to realise these things in the best way and still reap the benefits of linked data. So the API and installation instructions are mainly for people here at CeLeKT who have access to the binaries.
A little more useful for people outside the CeLeKT group is the Pinetree core ontology. While it was designed for the Pinetree system, the ontology makes it possible to represent the logical structure of digital content residing in content repositories in general. It has intentionally been kept simple to promote its reuse in other contexts that Pinetree.
A bit annoyingly is that the W3C RDF validator service refuses to validate the ontology when using the “Check by URI” option, but if I paste the ontology into the “Direct Input” textfield it validates perfectly. My initial suspicion is directed towards the FTP server at my web hosting service but I’m out of clues at this point. If anyone have had the same experience I’d be happy to hear from you.

As of yesterday I am back at the office again after becoming father to a beautiful little girl. Due to circumstances related to her birth, my research and studies were pretty much put on hold for six weeks, so the autumn semester for me officially begins now. During my time away a colleague of mine presented an article we wrote for the MobileHCI 2009 conference in Bonn, Germany, with the research problem of how to increase the expressivity and interoperability of contextual metadata depict mobile media objects. The full reference is located in the publications section of this blog, and while I was at it I added a reference to the paper presented at the MMedia 2009 conference.
The master plan to reach my licentiate during the spring of 2010 is somewhat progressing. As of now I am lacking the final paper to be embedded into the thesis and, fortunately for me, the deadline for the WMUTE 2010 conference was conveniently extended to mid October. So right now I’m busy working on a draft to a joint publication with two colleagues here at Växjö University, in which we are exploring the potential of using Linked Data to enrich digital content that emerge from learning with contextual metadata. I am really excited about the progress so far and hopefully it will serve as a smooth bridge towards my future research. In fact I better get back to work now. Later!
One last thing, I came across a neat workshop on Linked Data on the Web with lots of articles to digest. Check it out!
Another article accepted

The sun is shining like crazy outside on this nice spring day while I’m stuck inside in our office. Right now we do not even have a window to look out through due to the construction work going on outside. The upside of the coin is that we’re getting a shiny new office somewhere in May. Sweet. Anyhow, earlier this week I received good news: my article sent to the MMEDIA09 conference has been accepted. It seems like the jigsaw pieces are falling into place and that I will have the articles I need for my licentiate (half-way) PhD thesis in time.
The rest of the afternoon will be spent on some coding and API documentation for the Pinetre content repository, and my intention is to add a project page here on my site describing the system a little bit further. Right now the only formal description of it is in a soon to be published article where the detailed info were left out because of spatial constraints.
Now back to work, enjoy Easter!
Welcome to my new fancy blog
February 18th, 2009
This is one of those “welcome to my new fancy blog” posts. While the blog section is not intended to be the main section of the casualsemantics.se site, I realized that I need somewhere to keep track of my thoughts and ideas. Not all of them will be work related; some crazy stuff might appear here as well.
Now, some words on the domain name. After spending a lot of time trying to figure out a neat name I consulted some colleagues. In our discussion we came up with “semantics” as one of my current focus areas is on Semantic Web technologies. The prefix “casual” is more related to my personality. So yeah, a little of my interest mixed up with a little of me resulted in casual semantics. There you have it, whether you like it or not.
