Open The Door To Bringing Linked Data To Real-World Projects

ld1Linked Data: Structured Data on the Web is now available in a soft-cover edition. The book, authored by David Wood, Marsha Zaidman, Luke Ruth, and Michael Hausenblas, and with a forward by Tim Berners-Lee, aims to give mainstream developers without previous experience with Linked Data practical techniques for integrating it into real-world projects, focusing on languages with which they’re likely to be familiar, such as JavaScript and Python.

Berners-Lee’s forward gets the ball rolling in a big way, making the case for Linked Data and its critical importance in the web ecosystem:“The Web of hypertext-linked documents is complemented by the very powerful Linked Web of Data.  Why linked?  Well, think of how the value of a Web page is very much a function of what it links to, as well as the inherent value of the information within the Web page. So it is — in a way even more so — also in the Semantic Web of Linked Data.  The data itself is valuable, but the links to other data make it much more so.”

The topic has clearly struck a nerve, Wood believes, noting that today we are “at a point where structured data on the web is getting tremendous play,” from Google’s Knowledge Graph to the Facebook Open Graph protocol, to the growing use of the schema.org vocabulary, to data still growing exponentially in the Linked Open Data Project, and more. “The industry is ready to talk about data and data processing in a way it never has been before,” he continues. There’s growing realization that Linked Data fits in with and nicely complements technologies in the data science realm, such as machine learning algorithms and Hadoop, such that “you can suddenly build things you never could before with a tiny team, and that’s pretty cool….No technology is sufficient in and of itself but combine them and you can do really powerful things.”

IT leaders keeping an eye on Gartner’s top tech trends list know that early in March semantic technologies made the cut (see our original story here, and our follow-up with one of the authors of the Gartner report here). The big question for many enterprise IT pros, though, is what should they be doing with that knowledge – how can they start leveraging semantic technology to their own organizations’ benefit?

Help is on the way. Three experts in semantic web technologies and Linked Data weigh in with their advice on heading down that road:

Semantic Tech: It’s Moving Mainstream, Playing To The Data-Is-An-Asset Crowd, And Living Life Out Loud

At the recent SemTech conference in NYC, The Semantic Web Blog had an opportunity to ask some leaders in the field about where semantic technology has been, and where it’s going.

David Wood, CTO, 3RoundStones:

The short take: Hiring has been on in a big way at semantic tech players as enterprises are moving in greater numbers to buy semantic software, recognizing their traditional vendors won’t solve their interoperability issues. Sem tech vendors should have a happy 2013 as semantics continues going mainstream.

The full take:

As part of that launch, Manning is offering a one-day 50% discount for readers of SemanticWeb.com. The discount applies to all versions of “Linked Data”: eBook, print books, and Manning’s “MEAP” books (more on MEAP below). To claim the discount, use coupon code “12linksw” when ordering.

This offer expires at 11:59 pm (US EST) on December 6, so if you’re interested, act fast!

About the Book (description by David Wood):

The flexible, unstructured nature of the Web is being extended to act as a global database of structured data. Linked Data is a standards-driven model for representing structured data on the Web that gives developers, publishers, and information architects a consistent, predictable way to publish, merge and consume data. The Linked Data model offers the potential to standardize Web data in the same way that SQL standardized large-scale commercial databases. Linked Data has been adopted by many well-known institutions, including Google, Facebook, IBM, Oracle and government agencies, as well as popular Open Source projects such as Drupal.

Centralized Data Repositories: An Idea Whose Time Has Come, And Gone

Is it time for the enterprise to lose the idea of the holy grail of a central repository of multi-sourced data?

Experts in the semantic web space think that’s the case. At the recent Semantic Web Technology and Business Conference in New York City, a few weighed in on the issue.

Pharma Becoming Ever-Bigger Fan of Semantic Technology

At the Semantic Technology and Business Conference in New York City last week, attendees got to hear a lot about how semantic technology is influencing various sectors, such as government (see our stories here and here) and media (see this article and this one). Another prominent one on display: pharmaceuticals.

Pharma, for example, was the driving use case for the update to Callimachus that focuses on helping users deal with data that’s external to the framework for data-driven applications, David Wood, CTO of Callimachus project sponsor 3 Round Stones, told The Semantic Web Blog at the event. (To learn more about the update, see our story here.)

A session on Tuesday last week saw Lee Feigenbaum, vp of marketing at Cambridge Semantics, which makes the Anzo express and Anzo Enterprise solutions,  put forth a case for semantic tech as being key to data integration and interoperability in the sector, as well. “Can semantic web technologies break down enterprise data silos just as they break down document silos on the web?” he said. “The answer to the question is, “Of course.” Compared to the web, the data silo challenges of even the largest pharmaceuticals organization is relatively minor.”

Callimachus Update Has Big Implications for Data Interoperability

Callimachus is getting an update. It’s been quiet for a few months over at the framework for data-driven applications based on Linked Data principles, but with good reason, says David Wood, CTO of Callimachus project sponsor 3 Round Stones. 3 Round Stones also offers Callimachus Enterprise, winner of this year’s Startup Competition at the Semantic Technology and Business Conference in San Francisco.

Big things were on the menu for this release, which should emerge from beta today. To date, all the RDF that Callimachus has dealt with has been local to it, Wood explains. “People have been saying for ages, ‘But I don’t want to copy the LOD cloud into Callimachus to deal with it. I want to deal with a lot of data out there in the world, in enterprise systems, an Oracle server, or the LOD cloud,” he says.

The new release takes on the challenge of dealing with data that’s external to Callimachus.

Where is semantic technology better poised to be better commercialized – the U.S. or Europe? With The Semantic Business and Technology conference heading across the ocean to the U.K. next month, it seems a good time to provide some perspective on the question.

At the last SemTech conference in San Francisco, 3RoundStones took first place in the Startup competition with Callimachus Enterprise. During a discussion of some of the product’s winning features, talk turned to some of the differences between how semantic technology has progressed in the States and overseas.

As the Semantic Web Blog recently noted, 3RoundStones’ Callimachus Enterprise emerged as the winner of the Top Semantic Technology Start-up competition that was held at the Semantic Tech & Business Conference (#SemTechBiz) in San Francisco a few weeks ago. The commercially supported Linked Data Management system, now being piloted by eight companies, will this summer be released to the general public as Version 1.0.

Callimachus Enterprise is distinguished not only by its technology, but by CTO David Wood’s presentation that spoke to the real business needs of the enterprise today – including rapidly demonstrating value, in its case around exposing, connecting and visualizing disparate enterprise content – and also in that it provides a way for organizations to deal with their enterprise information in an entirely cloud-based solution. It leverages the Amazon cloud.

“A lot of companies are using cloud-based solutions for travel and expense tracking,” says CEO Bernadette Hyland. “But this is the beginning of a new wave.”
