The role of Role in Schema.org
This post is about an unusual, but very useful, aspect of the Schema.org vocabulary — the Role type.

A Step for Schema.org – A Leap for Bib Data on the Web
Several significant bibliographic related proposals were brought together in a package which I take great pleasure in reporting was included in the latest v1.9 release of Schema.org
WorldCat Works – 197 Million Nuggets of Linked Data
They’re released! A couple of months back I spoke about the preview release of Works data from WorldCat.org. Today OCLC published a press release announcing the official release of 197 million descriptions of bibliographic Works. A Work is a high-level description of a resource, containing information such as author, name, descriptions, subjects etc., common to all editions of the work. The description format is based upon some of the properties defined by the CreativeWork type from the Schema.org vocabulary. In the case of a WorldCat Work description, it also contains [Linked Data] links to individual, OCLC numbered, editions already shared …
Visualising Schema.org
One of the most challenging challenges in my evangelism of the benefits of using Schema.org for sharing data about resources via the web is that it is difficult to ‘show’ what is going on. The scenario goes something like this….. “Using the Schema.org vocabulary, you embed data about your resources in the HTML that makes up the page using either microdata or RDFa….” At about this time you usually display a slide showing html code with embedded RDFa. It may look pretty but the chances of more than a few of the audience being able to pick out the schema:Book …
WorldCat Works Linked Data – Some Answers To Early Questions
Since announcing the preview release of 194 Million Open Linked Data Bibliographic Work descriptions from OCLC’s WorldCat, last week at the excellent OCLC EMEA Regional Council event in Cape Town; my in-box and Twitter stream have been a little busy with questions about what the team at OCLC are doing. Instead of keeping the answers within individual email threads, I thought they may be of interest to a wider audience: Q I don’t see anything that describes the criteria for “workness.” “Workness” definition is more the result of several interdependent algorithmic decision processes than a simple set of criteria. To …
OCLC Preview 194 Million Open Bibliographic Work Descriptions
demonstrating on-going progress towards implementing the strategy, I had the pleasure to preview two upcoming significant announcements on the WorldCat data front: 1. The release of 194 Million Linked Data Bibliographic Work descriptions. 2. The WorldCat Linked Data Explorer interface
OCLC Declare OCLC Control Numbers Public Domain
Little things mean a lot. Little things that are misunderstood often mean a lot more. Take the OCLC Control Number, often known as the OCN, for instance. Every time an OCLC bibliographic record is created in WorldCat it is given a unique number from a sequential set – a process that has already taken place over a billion times. The individual number can be found represented in the record it is associated with. Over time these numbers have become a useful part of the processing of not only OCLC and its member libraries but, as a unique identifier proliferated across …
Content-Negotiation for WorldCat
I am pleased to share with you a small but significant step on the Linked Data journey for WorldCat and the exposure of data from OCLC. Content-negotiation has been implemented for the publication of Linked Data for WorldCat resources. For those immersed in the publication and consumption of Linked Data, there is little more to say. However I suspect there are a significant number of folks reading this who are wondering what the heck I am going on about. It is a little bit techie but I will try to keep it as simple as possible. Back last year, a …
Putting WorldCat Data Into A Triple Store
I can not really get away with making a statement like “Better still, download and install a triplestore [such as 4Store], load up the approximately 80 million triples and practice some SPARQL on them” and then not following it up. I made it in my previous post Get Yourself a Linked Data Piece of WorldCat to Play With in which I was highlighting the release of a download file containing RDF descriptions of the 1.2 million most highly held resources in WorldCat.org – to make the cut, a resource had to be held by more than 250 libraries. So here …
Get Yourself a Linked Data Piece of WorldCat to Play With
You may remember my frustration a couple of months ago, at being in the air when OCLC announced the addition of Schema.org marked up Linked Data to all resources in WorldCat.org. Those of you who attended the OCLC Linked Data Round Table at IFLA 2012 in Helsinki yesterday, will know that I got my own back on the folks who publish the press releases at OCLC, by announcing the next WorldCat step along the Linked Data road whilst they were still in bed. The Round Table was an excellent very interactive session with Neil Wilson from the British Library, Emmanuelle Bermes from Centre …
