All in all, I believe the campaign has been surprisingly effective on the visible web. However, what prompted this post was trying to ascertain how effective it was on the Data Web, which almost by definition is the invisible web. Ahead of the dark day, a move started on the Semantic Web and Linked Open Data mailing lists to replicate what Wikipedia was doing by going dark on Dbpedia
The Linked Data movement was kicked off in mid 2006 when Tim Berners-Lee published his now famous Linked Data Design Issues document. Many had been promoting the approach of using W3C Semantic Web standards to achieve the effect and benefits, but it was his document and the use of the term Linked Data that crystallised it, gave it focus, and a label.
In 2010 Tim updated his document to include the Linked Open Data 5 Star Scheme
Although there has been a half year lag between the the workshop held at Stanford University, at the end of June 2011, and the Stanford Linked Data Workshop Technology Plan [pdf] published on December 31st, the folks behind it obviously have not been twiddling their thumbs.
It is great to launch a new venture, and I am looking forward to launching this one – Data Liberate. Having said that, there is much continuity in this step. Those that know me from the conference circuit, my work with the Talis Group and more recently with Talis Consulting, will recognise much in the core of what Data Liberate has to offer.
