HTML5: The Party Is Officially On!

w3chtmlWord came from the World Wide Web Consortium (W3C) yesterday that it has published the 5th major revision of HTML, the core language of the web. While HTML5 is already in use by developers (having become a W3C candidate recommendation a couple of years ago), the recommendation for the standard is a lynchpin for the community, as it now formalizes stable guidelines for the development of innovative and cross-platform web sites and applications.

A key feature of HTML5 – the first major new HTML standard in more than a decade – is that it provides the ability to describe the structure of a web document with standard semantics. It uses semantic tags for things like page headers, footers, body, ordered lists, time, and more to better identify an element and how it is being used. Greater use of these tags should improve a browser’s ability to understand content for display across a range of devices and screen sizes without requiring any development rejiggering, and search engines’ ability to more effectively index a page, which could lead to better rankings.

W3C Publishes Linked Data Platform Best Practices and Guidelines

Photo of Arnaud Le Hors presenting the LDP at SemTechBiz 2014The W3C’s Linked Data Platform (LDP) Working Group has published a document outlining best practices and guidelines for implementing Linked Data Platform servers and clients. The document was edited by Cody Burleson, Base22, and Miguel Esteban Gutiérrez and Nandana Mihindukulasooriya of the Ontology Engineering Group, Universidad Politécnica de Madrid.

For those new to LDP, has recently published the following materials:

WEBINAR: “Getting Started with the Linked Data Platform (LDP)” with LDP Working Group Chair, Arnaud Le Hors, IBM (pictured above presenting LDP work at the SemTechBiz conference last week).

ARTICLE: “Introduction to: Linked Data Platform” by Cody Burleson, Base 22

Those ready to dive into the nuts and bolts of the document will find detailed guidance on topics such as:

  • Predicate URIs
  • Use of relative URIs
  • Hierarchy and container URIs
  • Working with fragments
  • Working with standard datatypes
  • Representing relationships between resources
  • Finding established vocabularies

…and much more. See the full document at congratulates the Working Group on this step and looks forward to reporting on use cases and implementations of LDP.

WEBINAR: Getting Started with the Linked Data Platform (LDP)

WEBINAR Title slide: Getting Started with the Linked Data PlatformIn case you missed Monday’s webinar, “Getting Started with the Linked Data Platform (LDP)” delivered by Arnaud Le Hors of IBM, the recording and slides are now available (and posted below). The webinar was co-produced by and 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.

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.

It’s Time To Get Formal With Linked Data

It’s time to get real with Linked Data. The World Wide Web Consortium’s Linked Data Platform Working Group, convened almost a year ago, is on the case, with expectations by June to publish a last call working draft of the specification, and to have a final recommendation, the last stage of the W3C’s standards process, by early next year.

“The Linked Data Platform is expanding on the concept [originally] put forward by Tim Berners-Lee on his web site, to turn it into a specification,” says Arnaud J. Le Hors, co-chair of the working group and IBM’s Linked Data Standards Lead. He will address the work at this session during next month’s SemTechBiz conference in San Francisco.

Why the need to formalize Linked Data?  While there is a fairly significant list of W3C standards around the Semantic Web, the more loosely-defined Linked Data has led to an environment where interoperability suffers. That’s because people are left to solve the same problems, such as those around publishing and retrieving data, over and over again, and they take different paths to get there, Le Hors says. The guides that are out there are just that, guides, with people free to use or ignore them, if they can even find them – which in itself isn’t easy to do for those who aren’t well-informed members of the community, he says.

The Linked Data Platform extends the model to provide the industry with a formal definition for read-write access to Linked Data; it mandates publishing data in a standard format, RDF, and using a standard protocol, HTTP, “which is completely symmetrical with the way the web works today, with HTML and HTTP,” Le Hors says.

Linked Data Platform 1.0 Working Draft Published

World Wide Web Consortium LogoThe W3C has published a Working Draft of the Linked Data Platform 1.0

Earlier this year, the Linked Data Working Group was formed in response to a member submission (Full Disclosure: was a co-sponsor of that submission).  The original proposal put forward by IBM stated the need as, “We believe that Linked Data has the potential to solve some important problems that have frustrated the IT industry for many years, or at least to make significant advances in that direction. But this potential will be realized only if we can establish and communicate a much richer body of knowledge about how to exploit these technologies. In some cases, there also are gaps in the Linked Data standards that need to be addressed.”

As a working draft, the document published yesterday is open for public review, but The Linked Data Platform work represents a significant move forward in the creation of a standard for building enterprise systems around Linked Data. The document lays out “A set of best practices and simple approach for a read-write Linked Data architecture, based on HTTP access to web resources that describe their state using RDF.”

IBM and the Linked Data Platform Working Group

[Editor’s Note: was a co-sponsor of the Linked Data Platform proposal that led to the creation of the Linked Data Platform Working Group discussed here.]

Ian Jacobs reports, “Shortly after W3C announced the launch of the Linked Data Platform Working Group, I spoke with Arnaud Le Hors about IBM’s interest in linked data and their decision to co-chair the Working Group.” Asked why IBM became involved with organizing the Linked Enterprise Data Patterns Workshop and the Linked Data Platform Working Group, Le Hors responded, “IBM has been involved in Semantic Web activities from the beginning, but primarily from a research perspective. Until recently we had no products using the technology. Now we have IBM Rational, which develops a set of tools for application and product lifecycle management (requirements, bugs, etc.). Other parts of IBM are actively exploring it for complementary purposes. Customers typically use tools from more than one vendor and require integration; this is a problem IBM addresses.” Read more
