Semantic Web at Opera

Posts tagged with "Development"

Thanks for the parting gift...

, ,

It is with regret that I say good luck to Kjetil in his new job, and that I am grateful for the work he has done at Opera over the last couple of years. May our paths cross again.

As a sort of delayed good-bye present, the SIOC submission that he worked on, along with people from other companies and organisations, has been published by W3C, along with some interesting comments on SIOC by Ivan Herman.

People would be aware that we already have some of this infrastructure in place. Unfortunately with Kjetil moving on, I suspect our progress will slow down for a while. He is a hard man to replace. But any comments or feedback on what we have done right, and where we should be looking to go now, is welcome and will be taken into account as we carry on...

A new semweb widget...

, , , ...

People ask from time to time what you can do with widgets. Although you can make a "Hello world" widget (the instructions fit on a business card) it seems that this is a little simplistic for most people. Instead they make a clock widget.

Beautiful as some of these are (mine, for example :wink: ) they are not in themselves the thing the world needed most. But every so often something comes along that has real value. I think the first semweb widget was Jibberjim's Widgnaut, a widget version of foafnaut that crawled My.Opera's FOAF data. (Since we added the possibility to link your My.Opera FOAF to external files, it isn't a walled garden, just a starting point. Kjetil++! :smile: ).

Today we released a new widget - the tabulator widget version of Tim Berners-Lee's tabulator, which is a generic RDF browser. This means that now available for your delectation, an RDF browser running in Opera. I'm waiting to see how it works when widgets are released on mobile browsers, but please, get Opera 9 (or 9.01) if you haven't already, download the widget, and give it a try.

Many thanks to David Håsäther who did the widgetising and debugging to make it work cross-platform, Tim and all the folks who have worked on the tabulator project, JibberJim for building the RDF parser in the first place (way back when) and Gorm for making that work in Opera too.
