Opinions on open source and standards

Linked Data

Several months ago I edited my “About” text on this blog to add that: “After several years focusing on strategic and policy issues related to open source and standards, including in the emerging markets, I am back to more technical work.”

One of the projects that I have been working on in this context is Linked Data.

It all started over a year ago when I learned from the IBM Rational team that Linked Data was the foundation of Open Services for Lifecycle Collaboration Lifecycle (OSLC) which Rational uses as their platform for application integration. The Rational team was very pleased with the direction they were on but reported challenges in using Linked Data. They were looking for help in addressing these.

Fundamentally, the crux of the challenges they faced came down to a lack of formal definition of Linked Data. There is plenty of documentation out there on Linked Data but not everyone has the same vision or definition. The W3C has a growing collection of standards related to the Semantic Web but not everyone agrees on how they should be used and combined, and which one applies to Linked Data.

The problem with how things stand isn’t so much that there isn’t a way to do something. The problem is rather that, more often than not, there are too many ways. This means users have to make choices all the time. This makes starting to use Linked Data difficult for beginners and it hinders interoperability because different users make different choices.

I organized a teleconference with the W3C Team in which we explained what IBM Rational was doing with Linked Data and the challenges they were facing. The W3C team was very receptive to what we had to say and offered to organize a workshop to discuss our issues and see who else would be interested.

The Linked Enterprise Data Patterns Workshop took place on December 6 and 7, 2011 and was well attended. After a day and a half of presentations and discussions the participants found themselves largely agreeing and unanimously concluded that: the W3C should create a Working Group to create a Recommendation that formally defines a “Linked Data Platform”.

The workshop was followed by a submission by IBM and others of the Linked Data Basic Profile and the launch by W3C of the Linked Data Platform (LDP) Working Group (WG) which I co-chair.

You can learn more about this effort and IBM’s position by reading the “IBM on the Linked Data Platform” interview the W3C posted on their website and reading the “IBM lends support for Linked Data standards through W3C group” article I published on the Rational blog.

On a personal level, I’ve known about the W3C Semantic Web activities since my days as a W3C Team Member but I had never had the opportunity to work in this space before so I’m very excited about this project. I’m also happy to be involved again with the W3C where I still count many friends. 🙂

I will try to post updates on this blog as the WG makes progress.
