Semantic Web and Digital Libraries Conference (cont.)

A few years ago I had the pleasure to participate at a conference on Semantic Web and Digital Libraries, and I also wrote a short blog about it back then. That blog also included:

My main issue is, however, whether this conference was a one time shot or the beginning of a series. If there is no continuation, then the initiative may not have a long-lasting effect after all. And that would be a pity. It would really be good if somebody picked up the ball and turned this into some sort of a series…

Well, I am happy to see that it was not an isolated event after all, and there will be a new conference in the series in Trento, Italy, in September this year. Details are still missing but that is all right. The important thing is that the momentum is not lost!

A different usage of RDFa…

Talis and the University of Plymouth have just published a new SW Case Study at W3C. It is really a nice system which helps university students and instructors alike. There is no need for me to go into the details of the case study (I would probably not do justice anyway), it is much better if you read it right at the source

However, there is a small detail (compared to the rest of the study) that caught my attention because it describes a possible usage of RDFa that, I must admit, I did not consider before. Indeed, here is what the text says:

The interface to build or edit lists uses a WYSIWYG metaphor implemented in Javascript operating over RDFa markup, allowing the user to drag and drop resources and edit data quickly, without the need to round trip back to the server on completion of each operation. The user’s actions of moving, adding, grouping or editing resources directly manipulate the RDFa model within the page. When the user has finished editing, they hit a save button which serialises the RDFa model in the page into an RDF/XML model which is submitted back to the server. The server then performs a delta on the incoming model with that in the persistent store. Any changes identified are applied to the store, and the next view of the list will reflect the user’s updates.
