The Semantic Web’s Rocking, And There Ain’t No Stopping It Now

archerMake no mistake about it: The semantic web has been a success and that’s not about to stop now. That was essentially the message delivered by W3C Data Activity Lead Phil Archer, during his keynote address celebrating the semantic web’s ten years of achievement at last month’s Semantic Technology & Business Conference in San Jose.

After acknowledging that he’s heard it all about the semantic web being a failure, about it being rebranded as Linked Data and that being a failure too, he summed up those impressions in one distinctly British word: “Bollocks.” The list of successes ranged across the spectrum, from the use in federated data portals of the Data Catalog Vocabulary from the W3C’s Government Linked Data Working Group, to the 47-million triples strong Open Phacts pharmacology discovery platform, to all the job postings that come up on The Semantic Web Blog – including one recently for the J. Craig Venter Institute, named for the pioneer genomic researcher who sequenced the human genome, which is looking for a bioinformatics analyst with OWL expertise in his or her resume.

That’s just a taste of the many citations he offered of the semantic web’s successes to date, not least among them his own strong familiarity with Linked Data’s use in government, where the technologies, he said, are used “to make our government more efficient” by having one organization make an authoritative data set the others can link to to support data-sharing across agencies.

You Can Help Make Linked Data Core To The Future of Identity, Payment On The Web Platform

ld1At the end of September, The World Wide Web Consortium (W3C) may approve the world’s first Web Payments Steering Group, to explore issues such as navigating around obstacles to seamless payments on the web and ways to better facilitate global transactions while respecting local laws. Identity and digital signatures have a role here, at the same time as they go beyond the realm of payment into privacy and other arenas. At the end of October, there also will be a W3C technical plenary, to discuss identity, graph normalization, digital signatures and payments technologies.

Expect Linked Data to come up in the context of both events, Manu Sporny told attendees at this August’s 10th annual Semantic Technology & Business conference in San Jose during his keynote address, entitled Building Linked Data Into the Core of the Web. “It is the foundational data model to build all this technology off of,” said Sporny, who is the founder and CEO of Digital Bazaar, which develops technology and services to make it easier to buy and sell digital content over the Internet. (See our stories about the company and its technology here.)  He also is founder and chair of the W3C Web Payments Community Group, chair of its RDFa Working Group, and founder, and chair and lead editor of the JSON-LD Community Group.

The webinar was co-produced by SemanticWeb.com and DATAVERSITY.net and runs for one hour, including a Q&A session with the audience that attended the live broadcast.

The presenter will also deliver a session that offers a deeper dive into LDP at the upcoming Semantic Technology & Business Conference: “The W3C Linked Data Platform,” and immediately following that session, Sandro Hawke, W3C staff, will present, “Building Social Applications with the W3C Linked Data Platform (LDP).

Registration for the conference is now open.

If you watch this webinar, please use the comments section below to share your questions, comments, and ideas for webinars you would like to see in the future.

About the Webinar

Linked Data Platform (LDP), the latest W3C standard for Linked Data, brings REST to Linked Data. LDP defines a standard way to access, create, and update RDF resources over HTTP. With this new capability, businesses can use Linked Data for data integration in read/write mode.

This webinar will introduce you to this new standard, explaining what’s in it and how it fits with other standards like SPARQL. You will have a basic understanding of what you can expect to be able to do with this new technology so you can plan on how to best leverage it in your future business applications.

Introduction to: Linked Data Platform

Nametag: Hello, my name is Linked Data PlatformIn its ongoing mission to lead the World Wide Web to its full potential, the W3C recently released the first specification for an entirely new kind of system. Linked Data Platform 1.0 defines a read-write Linked Data architecture, based on HTTP access to web resources described in RDF. To put that more simply, it proposes a way to work with pure RDF resources almost as if they were web pages.

Because the Linked Data Platform (LDP) builds upon the classic HTTP request and response model, and because it aligns well with things like REST, Ajax, and JSON-LD, mainstream web developers may soon find it much easier to leverage the power and benefits of Linked Data. It’s too early to know how big of an impact it will actually make, but I’m confident that LDP is going to be an important bridge across the ever-shrinking gap between todays Web of hyperlinked documents and the emerging Semantic Web of Linked Data. In today’s post, I’m going to introduce you to this promising newcomer by covering the most salient points of the LDP specification in simple terms. So, let’s begin with the obvious question…

 

What is a Linked Data Platform?

A Linked Data Platform is any client, server, or client/server combination that conforms in whole or in sufficient part to the LDP specification, which defines techniques for working with Linked Data Platform Resources over HTTP. That is to say, it allows Linked Data Platform Resources to be managed using HTTP methods (GET, POST, PUT, etc.). A resource is either something that can be fully represented in RDF or otherwise something like a binary file that may not have a useful RDF representation. When both are managed by an LDP, each is referred to as a Linked Data Platform Resource (LDPR), but further distinguished as either a Linked Data Platform RDF Source (LDP-RS) or a Linked Data Platform Non-RDF Source (LDP-NR).

Government Linked Data Goes With George Thomas

[EDITOR'S NOTE: Thank you to John Breslin for authoring this guest post remembering our friend and colleague, George Thomas.]

Photo of George ThomasWhen writing about a person’s significant achievements, it would be so much better if the person themselves could hear the good things you were saying about them. Unfortunately, the person I am writing about, George Thomas, passed away last week after a long battle with cancer. However, I think it is important to note the huge impact that George had on Government Linked Data, Linked Data in general, and on his friends and colleagues in the Semantic Web space. If there’s one name that Government Linked Data ‘goes with’, it would be George Thomas.

Although I only physically met George a handful of times, I would count him as one of those who influenced me the most – through his visionary ideas, his practical nature, his inspiring talks at conferences like SemTechBiz, and his willingness to build bridges between people, communities, and of course data.

For those who may not have met him, George worked in the US Government for the past 12 years – most recently as an enterprise architect in the US Department of Health and Human Services (HHS) – and previously he held Chief Architect/CTO roles in other agencies and various private companies.

I first came across George when he was Chief Architect at the CIO’s office in the US General Services Administration. He had given a presentation about how Semantic Web technologies similar to SIOC could potentially be used to “track the dollar instead of the person” on Recovery.gov. Later on, DERI’s Owen Sacco and I collaborated with George on a system to create and enforce fine-grained access control policies (using PPO/PPM) for the HHS’s Government Linked Data on IT investments and assets stored in multiple sources. (George also sung DERI’s praises in a blog post on Data.gov – “Linked Data Goes With DERI” – echoed in this article’s title.)

Schema.org Takes Action

actionstatusThis week saw schema.org introduce vocabulary that enables websites to describe the actions they enable and how these actions can be invoked, in the hope that these additions will help unleash new categories of applications, according to a new post by Dan Brickley.

This represents an expansion of the vocabulary’s focus point from describing entities to taking action on these entities. The work has been in progress, Brickley explains here, for the last couple of years, building on the http://schema.org/Action types added last August by providing a way of describing the capability to perform actions in the future.

The three action status type now includes PotentialActionStatus for a description of an action that is supported, ActiveActionStatus for an in-progress action, and CompletedActionStatus, for an action that has already taken place.

The Web Is 25 — And The Semantic Web Has Been An Important Part Of It

web25NOTE: This post was updated at 5:40pm ET.

Today the Web celebrates its 25th birthday, and we celebrate the Semantic Web’s role in that milestone. And what a milestone it is: As of this month, the Indexed Web contains at least 2.31 billion pages, according to WorldWideWebSize.  

The Semantic Web Blog reached out to the World Wide Web Consortium’s current and former semantic leads to get their perspective on the roads The Semantic Web has traveled and the value it has so far brought to the Web’s table: Phil Archer, W3C Data Activity Lead coordinating work on the Semantic Web and related technologies; Ivan Herman, who last year transitioned roles at the W3C from Semantic Activity Lead to Digital Publishing Activity Lead; and Eric Miller, co-founder and president of Zepheira and the leader of the Semantic Web Initiative at the W3C until 2007.

While The Semantic Web came to the attention of the wider public in 2001, with the publication in The Scientific American of The Semantic Web by Tim Berners-Lee, James Hendler and Ora Lassila, Archer points out that “one could argue that the Semantic Web is 25 years old,” too. He cites Berners-Lee’s March 1989 paper, Information Management: A Proposal, that includes a diagram that shows relationships that are immediately recognizable as triples. “That’s how Tim envisaged it from Day 1,” Archer says.

The Audible Web?

4435941091_0b71388773

Reuven Cohen of Forbes recently wrote, “New audible interaction methods and API standards could be poised to usher in a new generation of web technology. Technology specifically tailored to interact with us as individuals rather than having us adapt to interact with the web. At the heart of this transformation is a new crop of technologies focused on natural language interaction through the use of verbal commands. In its most simple form, speech recognition is the ability to translate spoken words into text. The technology is certainly not a new concept; it has been around for almost 60 years. In 1954, the so-called Georgetown-IBM experiment was an influential demonstration of the first machine-based translation program.” Read more

RDF 1.1 is a W3C Recommendation

RDF 1.1Almost exactly 10 years after the publication of RDF 1.0 (10 Feb 2004, http://www.w3.org/TR/rdf-concepts/), the World Wide Web Consortium (W3C) has announced today that RDF 1.1 has become a “Recommendation.” In fact, the RDF Working Group has published a set of eight Resource Description Framework (RDF) Recommendations and four Working Group Notes. One of those notes, the RDF 1.1 primer, is a good starting place for those new to the standard.

SemanticWeb.com caught up with Markus Lanthaler, co-editor of the RDF 1.1 Concepts and Abstract Syntax document, to discuss this news.

photo of Markus LanthalerLanthaler said of the recommendation, “Semantic Web technologies are often criticized for their complexity–mostly because RDF is being conflated with RDF/XML. Thus, with RDF 1.1 we put a strong focus on simplicity. The new specifications are much more accessible and there’s a clear separation between RDF, the data model, and its serialization formats. Furthermore, the primer provides a great introduction for newcomers. I’m convinced that, along with the standardization of Turtle (and previously JSON-LD), this will mark an important point in the history of the Semantic Web.”
