Schema.org – Extending Benefits

I find myself in New York for the day on my way back from the excellent Smart Data 2015 Conference in San Jose. It’s a long story about red-eye flights and significant weekend savings which I won’t bore you with, but it did result in some great chill-out time in Central Park to reflect on the week.

In its long auspicious history the SemTech, Semantic Tech & Business, and now Smart Data Conference has always attracted a good cross section of the best and brightest in Semantic Web, Linked Data, Web, and associated worlds. This year was no different. In my new role as an independent working with OCLC and at Google.

I was there on behalf of OCLC to review significant developments with Schema.org in general – now with 640 Types (Classes) & 988 properties – used on over 10 Million web sites.

Baby Steps Towards A Library Graph

It is one thing to have a vision, regular readers of this blog will know I have them all the time, its yet another to see it starting to form through the mist into a reality. Several times in the recent past I have spoken of the some of the building blocks for bibliographic data to play a prominent part in the Web of Data.  The Web of Data that is starting to take shape and drive benefits for everyone.  Benefits that for many are hiding in plain site on the results pages of search engines. In those informational panels

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

From Records to a Web of Library Data – Pt2 Hubs of Authority

As is often the way, you start a post without realising that it is part of a series of posts – as with the first in this series.  That one – Entification, and the next in the series – Beacons of Availability, together map out a journey that I believe the library community is undertaking as it evolves from a record based system of cataloguing items towards embracing distributed open linked data principles to connect users with the resources they seek.  Although grounded in much of the theory and practice I promote and engage with, in my role as Technology
