OCLC WorldCat Linked Data Release – Significant In Many Ways

Posted on by Richard Wallis

Typical!  Since joining OCLC as Technology Evangelist, I have been preparing myself to be one of the first to blog about the release of linked data describing the hundreds of millions of bibliographic items in WorldCat.org. So where am I when the press release hits the net?  35,000 feet above the North Atlantic heading for LAX, that’s where – life just isn’t fair. By the time I am checked in to my Anahiem hotel, ready for the ALA Conference, this will be old news.  Nevertheless it is significant news, significant in many ways. OCLC have been at the leading edge …

Semantic Search, Discovery, and Serendipity

Posted on by Richard Wallis

An ambition for the web is to reflect and assist what we humans do in the real world. Search has only brought us part of the way. By identifying key words in web page text, and links between those pages, it makes a reasonable stab at identifying things that might be related to the keywords we enter.

As I commented recently, Semantic Search messages coming from Google indicate that they are taking significant steps towards the ambition. By harvesting Schema.org described metadata embedded in html

Linked Data a Recipe for Food?

Posted on by Richard Wallis

What relevance does Linked Data have for a City’s food supply you may ask. “We live in a world where the agri-food supply chain, from producer all the way through to final consumer, is extremely inefficient in the flow of knowledge.. ..with the application of Semantic Web and Linked Data technologies along the food supply chain, it will make it easier for all actors along there to know more about where their food comes from and where their food goes.”

Is Linked Data DIY a Good Idea?

Posted on by Richard Wallis

Most Semantic Web and Linked Data enthusiasts will tell you that Linked Data is not rocket science, and it is not.  They will tell you that RDF is one of the simplest data forms for describing things, and they are right.  They will tell you that adopting Linked Data makes merging disparate datasets much easier to do, and it does. They will say that publishing persistent globally addressable URIs (identifiers) for your things and concepts will make it easier for others to reference and share them, it will.  They will tell you that it will enable you to add value …

Free Data for 2.4 Million European Culture Heritage Items

Posted on by Richard Wallis

Europeana recently launched an excellent short animation explaining what Linked Open Data is and why it’s a good thing, both for users and for data providers.  They did this in support of the release of a large amount of Linked Open Data describing cultural heritage assets held in Libraries, Museums, Galleries and other institutions across Europe. The significant elements in the press release, from Europeana Professional (Europeana’s professional knowledge-sharing platform), are that they are releasing data for 2.4 million items, under a CC0 open data license, and it is Linked Data in RDF. This is a wonderful resource, and example …

Will This Flood of Open Data Wash Past Us?

Posted on by Richard Wallis

 @ePISplatform features fairly prominently in the stream of tweets that waft across my desktop every day – it comes from the European Public Sector Information (PSI) Platform (Europe’s One-stop Shop on PSI re-use) Working to stimulate and promote PSI re-use and open data initiatives. In amongst the useful pointers to news, comment, and documents, I have been recently conscious of an increasing flow of tweets like these: This is good news.  More and more city, local, national governments and public bodies releasing data as open data.  Of course the reference to open here is in relation to the licensing of …

Open Data: Digital Fuel or Raw Material?

Posted on by Richard Wallis

I have been reading with interest ‘Digital Fuel of the 21st Century: Innovation through Open Data and the Network Effect’ by Vivek Kundra. Well worth a read to place the current [Digital] Revolution we are somewhere in the middle of, in relation to preceding revolutions and the ages that they begat.

OK So Who Noticed the SOPA Blackout

Posted on by Richard Wallis

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

What Is Your Data’s Star Rating(s)?

Posted on by Richard Wallis

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

A New Beginning

Posted on by Richard Wallis

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.
