By now, most technical services librarians realize that
Linked Data is a topic of importance when considering the future of cataloging.
However, it is one thing to realize the importance of a topic and quite another
to feel empowered to learn about a topic. There are many resources about Linked
Data, but it can be overwhelming to figure out where to start in your
professional education on the topic. The
Linked Data Exploratorium, a product
of the Linked Data for Professional Education (LD4PE) project, is a
comprehensive resource that can go a long way toward reducing that feeling of
“Where do I start?”

The lead sponsors of LD4PE are the Institute for Museum and
Library Services, the Dublin Core Metadata Initiative, and the University of
Washington iSchool. According to the
Project
History page on their web site, the goal of the project is to create “an
online learning environment in support of instruction in the principles and
practice of Linked Data – a ‘language lab’ of software-supported methods for
data processing and analysis.”
A distinctive feature of the Linked Data Exploratorium is
its competency framework. One hurdle for me when trying to learn about Linked
Data is the fact that I feel like I don’t even know what I need to learn.
The Competency Index (CI) breaks down the many
components of Linked Data into distinct competencies, or skills that people
looking to get involved in Linked Data projects should master. The Linked Data
Exploratorium web site provides some information about the
Competency
Index for Linked Data, and the CI is also available as a
Google
document, to allow for comments and feedback.
The Competency Index is a very detailed document, but the
main competencies addressed (which each have their own sub-competencies) are:
- Fundamentals of Resource
Description Framework
- Fundamentals of Linked Data
- RDF vocabularies and application
profiles
- Creating and transforming Linked
Data
- Interacting with RDF data
- Creating Linked Data applications
The Competency Index informs the organization of the
learning resources that have been gathered by the Linked Data for Professional
Education project for the Linked Data Exploratorium. It is possible to browse
the resources by competency, so you can identify the resources that most
closely relate to the skills and knowledge you wish to acquire. Overall, the
Linked Data Exploratorium looks like a great jumping-off point for those
looking to learn more about Linked Data.
