Deconstructing JSON-LD

Photo of (clockwise from top-left: Aaron Bradley, Greg Kellogg, Phil Archer, Stephane CorlosquetAaron Bradley recently posted a roundtable discussion about JSON-LD which includes: “JSON-LD is everywhere. Okay, perhaps not everywhere, but JSON-LD loomed large at the 2014 Semantic Web Technology and Business Conference in San Jose, where it was on many speakers’ lips, and could be seen in the code examples of many presentations. I’ve read much about the format – and have even provided a thumbnail definition of JSON-LD in these pages – but I wanted to take advantage of the conference to learn more about JSON-LD, and to better understand why this very recently-developed standard has been such a runaway hit with developers. In this quest I could not have been more fortunate than to sit down with Gregg Kellogg, one of the editors of the W3C Recommendation for JSON-LD, to learn more about the format, its promise as a developmental tool, and – particularly important to me as a search marketer – the role in the evolution of”

eXframe Platform Demos Power Of The Semantic Web For Biology

sccommonsA Drupal ++ platform for semantic web biomedical data – that’s how Sudeshna Das describes eXframe, a reusable framework for creating online repositories of genomics experiments. Das – who among other titles is affiliate faculty of the Harvard Stem Cell Institute – is one of the developers of eXframe, which leverages Stéphane Corlosquet’s RDF module for Drupal to produce, index (into an RDF store powered by the ARC2 PHP library) and publish semantic web data in the second generation version of the platform.

“We used the RDF modules to turn eXframe into a semantic web platform,” says Das. “That was key for us because it hid all the complexities of semantic technology.”

One instance of the platform today can be found in the repository for stem cell data as part of the Stem Cell Commons, the Harvard Stem Cell Institute’s community for stem cell bioinformatics. But Das notes the importance of the reusability aspect of the software platform to build genomics repositories that automatically produce Linked Data as well as a SPARQL endpoint, is that it becomes easy to build new repository instances with much less effort. Working off Drupal as its base, eXframe has been customized to support biomedical data and to integrate biomedical ontologies and knowledge bases.

Drupal Deepens Semantic Web Ties

semtechbiz-10th-125sqAmong the mainstream content management systems, you could make the case that Drupal was the first open source semantic CMS out there. At next week’s Semantic Technology and Business Conference, software engineer Stéphane Corlosquet of Acquia, which provides enterprise-level services around Drupal, and Bock & Co. principal Geoffrey Bock will discuss in this session Drupal’s role as a semantic CMS and how it can help organizations and institutions that are yearning to enrich their data with more semantics – for search engine optimization, yes, but also for more advanced use cases.

“It’s very easy to embed semantics in Drupal,” says Bock, who analyses and consults on digital strategies for content and collaboration. At its core it has the capability to manage semantic entities, and in the upcoming version 8 it takes things to a new level by including as a foundational data type. “It will become increasingly easier for developers to build and deliver semantically enriched environments,” he says, which can drive a better experience both for clients and stakeholders.

Corlosquet, who has taken a leadership role in building semantic web capabilities into Drupal’s core and maintains the RDF module in Drupal 7 and 8, explains that the closer embrace of in Drupal is of course a help when it comes to SEO and user engagement, for starters. Google uses content marked up using to power products like Rich Snippets and Google Now, too.

Reason To Be Thankful: Being Named A Fast-Growing Tech Company

rsz_thankful_imageIt’s got to be a happy Thanksgiving for a number of tech companies that made their way to Deloitte’s recently-released Technology Fast 500. The 2013 ranking of the fastest-growing tech companies based in North America also has something to show for anyone who’s doubted that there’s money to be made taking advantage of semantic and other Web 3.0 concepts, a look at the list should show it’s time for the doubting to stop.

Have a look at some of the winners with their overall rankings:

#2 Acquia. Drupal claims the title of being the first mainstream content management system to support semantic web technology in its core. The Drupal-powered project Acquia was co-founded by Drupal creator Dries Buytaert to provide cloud, SaaS, and other services to organizations building websites on Drupal – and has on staff software engineer Stéphane Corlosquet, who had a big hand in bringing those semantic capabilities to Drupal’s core. In fact, Corlosquet spoke at the most recent SemTechBiz about Acquia as an example of a Drupal-powered project managing its content as Linked Data.

Drupal 7 And The Linked Data Connection: Making For Smarter Web Experiences

As Linked Data matures across the web – courtesy of efforts such as that underway by the Linked Data Platform Working Group to mandate publishing data in RDF and to use the HTTP protocol, (see our story here) – anyone running a website is going to need to know how to manage it. That, says Geoffrey Bock, principal at strategic marketing and insight services firm  Bock & Company, is going to make the popular Drupal platform for managing web content even more important.

Drupal 7 brought to the platform the ability to manage semantic metadata by incorporating RDF as a core capability, in a module that outputs RDFa. From the end user’s point of view the task of managing the metadata is made very easy through the familiar editing environment, says Bock. He will be co-hosting the session, How Drupal 7 Manages Linked Data for Smart Web Experiences, at the SemTechBiz conference in San Francisco in June. He’ll be joined by Stéphane Corlosquet, software enginner at Acquia Inc., the company co-founded by Drupal creator Dries Buytaert, which provides cloud, SaaS, and other services to organizations building websites on Drupal. Corlosquet was a critical force in bringing semantic web capabilities to Drupal’s core, with roles including being the maintainer of the RDF module in Drupal 7 a member of the Drupal security team.

Drupal & Data Descriptions

Stéphane Corlosquet has written an article examining data descriptions for plugable serializations of Drupal entities. He writes, “There’s been lots of discussions on various approaches for serializing entities in the WSCCI group and with Drupal 8 feature freeze only a few months away, it’s time to start coding. JSON-LD was chosen as a potential good candidate for serializing Drupal entities. One of the key features of JSON-LD is the ability to include a @context along with your data. This context describes the data present in the JSON document and is useful for consumers to understand how to best make use of the data.” Read more

Q: What is “Structured Data on the Web” (the site and the concept)?

GK: We wanted to provide a place for people to learn about the different ways in which publishers can add semantic information to their web sites and applications. There is confusion in the marketplace, partly due to the introduction of, which has raised the awareness of structured data with web developers. is a one-stop-shop to learn about the different mechanisms available to developers to take advantage of this.

Stéphane Corlosquet Talks About Drupal 7

We’ve been covering the release of Drupal 7 for a while and we noticed that Stéphane Corlosquet gave an interview this week regarding the recent release of Drupal 7, the CMS product used to power over 1% of the world’s websites. Updates in Drupal 7 include additions of semantic web technologies, and Stephane is a major factor behind these updates.

An important change in Drupal 7 is the incorporation of the RDFa standard. In the interview, Stéphane comments that adding RDFa was the “next logical step beyond XHTML.” When asked about the concerns of many web developers regarding the complexity of adopting semantic technologies, Stéphane replied:

“Semantic Web technologies don’t have to be complicated when applied to simple use cases! We purposely chose only of a subset of semantic web technologies to integrate into the core of Drupal, keeping the learning curve for the Drupal developers and users as low as possible.”

Stéphane has contributed several patches to the Drupal core and is a member of the Drupal security team. Last year, Stéphane gave an excellent overview of his work with Drupal in a webcast.
