The Three Linked Data Choices for Libraries

We are [finally] on the cusp of establishing a de facto Linked Data approach for libraries and their system suppliers – not there yet but getting there.

We have a choice between BIBFRAME 2.0, Schema.org, Linky MARC and doing nothing.

Schema.org: Describing Global Corporations Local Cafés And Everything In-between

There have been  discussions in Schema.org about the way Organizations their offices, branches and other locations can be marked up; they exposed a lack of clarity in the way to structure descriptions of Organizations and their locations, offices, branches , etc.
To address that lack of clarity I thought it would be useful to share some examples here.

Testing Schema.org output formats

Part of my efforts working with Google in support of the Schema.org structured web data vocabulary, its extensions, usage and implementation, is to introduce new functionality and facilities on to the Schema.org site.

I have recently concluded a piece of work to improve accessibility to the underlying definition of vocabulary terms in various data formats, which is now available for testing and comment.

Hidden Gems in the new Schema.org 3.1 Release

I spend a significant amount of time working on the supporting software, vocabulary contents, and application of Schema.org. So it is with great pleasure, and a certain amount of relief, I share the release of Schema.org 3.1 and share some hidden gems you find in there.

Evolving Schema.org in Practice Pt3: Choosing Where to Extend

OK. You have read the previous posts in this series. You have said to yourself I only wish that I could describe [insert you favourite issue here] in Schema.org. You are now inspired to do something about it, or get together with a community of colleagues to address the usefulness of Schema.org for your area of interest. Then comes the inevitable question: Where do I focus my efforts – the core vocabulary or a Hosted Extension or an External Extension?

Evolving Schema.org in Practice Pt1: The Bits and Pieces

I am often asked by people with ideas for extending or enhancing Schema.org how they go about it.  These requests inevitably fall into two categories – either ‘How do I decide upon and organise my new types & properties and relate them to other vocabularies and ontology’ or ‘now I have my proposals, how do I test, share, and submit them to the Schema.org community?’

I touch on both of theses areas in a free webinar I recorded for DCMI/ASIS&T a couple of months ago.  It is in the second in a two part series Schema.org in Two Parts: From Use to Extension .  The first part covers the history of Schema.org and the development of extensions.  That part is based up on my experiences applying and encouraging the use of Schema.org with bibliographic resources, including the set up and work of the Schema Bib Extend W3C Community Group – bibliographically focused but of interest to anyone looking to extend Schema.org.

The focus of this post is in answering the now I have my proposals, how do I test, share, and submit them to the Schema.org community?

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
