Linked Open Data: A Beckoning Paradise

Share this post:

The following is a guest post by Gloria Gonzalez, a 2011 Junior Fellow working with NDIIPP.

Imagine an internet where every single webpage interconnects to other related information. While browsing a site about the history of the United States, for example, you could see digital versions of the documents that established it–with the click of a button. Or, while reading an article on an academic journal website, you could select a link that led to the primary sources or data collections used by the author. Wouldn’t it be useful to discover so much more information, without having to search for it?

This hypothetical internet would not only be an online researcher’s paradise; it would also drastically change how we all access information.

Luckily for us, such an internet is not only possible, but is slowly being created as you read this. How? Through the use of Linked Open Data, which gives us the ability to make the internet vastly more interconnected and interoperable.

If you’ve never heard of LOD, don’t worry. Two weeks ago, I myself didn’t know what it was. Since then, I’ve learned quite a bit about the topic while working for NDIIPP, and I’ve found the topic to be fascinating, which is why this is the first in a series of posts about LOD that I’ll be writing for The Signal.

The basic intent of LOD is to make information on the internet more discoverable.  It is an approach to publishing information according to standards that facilitate linkages between different information resources, such as web pages and datasets. Linked Data creates relationships between different sets of information by using Uniform Resource Identifiers (which is a fancy way to say web addresses, a.k.a. URLs) as distinct identifiers for information resources.

The “Open” in LOD is essential because the goal is to promote broad use of and access to information by libraries, archives, museums, governments–everybody!  When you have a vast amount of these linkages, the internet becomes truly web-like, with each site having significant relationships with other information resources.
