From MARC to BIBFRAME and Schema.org in a Knowledge Graph

The MARC ingestion pipeline is one of four pipelines that keep the Knowledge Graph, underpinning the LDMS, synchronised with additions, updates, and deletions from the many source systems that NLB curate and host.

Library Metadata Evolution: The Final Mile

When Schema.org arrived on the scene I thought we might have arrived at the point where library metadata  could finally blossom; adding value outside of library systems to help library curated resources become first class citizens, and hence results, in the global web we all inhabit.  But as yet it has not happened.

Bibframe – Schema.org – Chocolate Teapots

In a session at the IFLA WLIC in Kuala Lumpur – my core theme being that there is a need to use two [linked data] vocabularies when describing library resources — Bibframe for cataloguing and [linked] metadata interchange — Schema.org for sharing on the web for discovery.

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.

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 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 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
