Another announcement by Google this week – one that didn’t get quite as much play as the launch at I/O of Google Play Music All Access and improvements to its search, map and Google + services – was this: Support for JSON-LD markup in Gmail.
Manu Sporny, who has been instrumental in JSON-LD’s development and is one of the authors of the draft, heralds the news here in his blog, noting that it means that Gmail now will be able to recognize people, places, events and a variety of other Linked Data objects, and that actions may be taken on the Linked Data objects embedded in an e-mail. “For example, if someone sends you an invitation to a party, you can do a single-click response on whether or not you’ll attend a party right from your inbox. Doing so will also create a reminder for the party in your calendar,” he writes.
The news was greeted with enthusiasm on a W3C JSON LD message round, as, as Sporny describes it, “pretty big validation of the technology.”
While noting that Google followed the standard closely, Sporny does point out some issues with the implementation – including a major one that Google isn’t using the JSON-LD @context parameter correctly in its markup examples:
Schema.org, Learning Resource Metadata Initiative Join Hands In Boost To Educational Content Searches
Earlier this month word came of a revision to schema.org: Version 1.0a additions, according to this posting from Dan Brickley, include the Datasets vocabulary, and some supporting utility terms for describing schema.org types, properties and their inter-relationships. One of the gems in the update are additions related to the Learning Resource Metadata Initiative (LRMI), an effort led by the Association of Educational Publishers and Creative Commons, which has as its goals making it easier to publish, discover and delivery quality educational resources on the web. The Bill and Melinda Gates Foundation and the William and Flora Hewlett Foundation helped fund the work.
With schema.org serving as a catalyst for its work, the LRMI developed a common metadata framework for tagging online learning resources, with the idea of having that metadata schema incorporated into Schema.org. With that now the case, it’s possible for publishers or curators of educational content to use LRMI markup and have that metadata recognized by the major search engines.
“One of the reasons why education was one of the first extensions of schema.org is that the education industry is going through some very interesting times,” says Madi Weland Solomon, head of Data Architecture Standards at education company Pearson plc, one of the LRMI project launch partners.
As we close out 2012, we’ve asked some semantic tech experts to give us their take on the year that was. Was Big Data a boon for the semantic web, or is the opportunity to capitalize on the connection still pending? Is structured data on the web not just the future but the present? What sector is taking a strong lead in the semantic web space?
We begin with Part 1, with our experts listed in alphabetical order:
John Breslin, lecturer at NUI Galway, researcher and unit leader at DERI, creator of SIOC, and co-founder of Technology Voice and StreamGlider:
I think the schema.org initiative really gaining community support and a broader range of terms has been fantastic. It’s been great to see an easily understandable set of terms for describing the objects in web pages, but also leveraging the experience of work like GoodRelations rather than ignoring what has gone before. It’s also been encouraging to see the growth of Drupal 7 (which produces RDFa data) in the government sector: Estimates are that 24 percent of .gov CMS sites are now powered by Drupal.
Martin Böhringer, CEO & Co-Founder Hojoki:
For us it was very important to see Jena, our Semantic Web framework, becoming an Apache top-level project in April 2012. We see a lot of development pace in this project recently and see a chance to build an open source Semantic Web foundation which can handle cutting-edge requirements.
Still disappointing is the missing link between Semantic Web and the “cool” technologies and buzzwords. From what we see Semantic Web gives answers to some of the industry’s most challenging problems, but it still doesn’t seem to really find its place in relation to the cloud or big data (Hadoop).
Christine Connors, Chief Ontologist, Knowledgent:
One trend that I have seen is increased interest in the broader spectrum of semantic technologies in the enterprise. Graph stores, NoSQL, schema-less and more flexible systems, ontologies (& ontologists!) and integration with legacy systems. I believe the Big Data movement has had a positive impact on this field. We are hearing more and more about “Big Data Analytics” from our clients, partners and friends. The analytical power brought to bear by the semantic technology stack is sparking curiosity – what is it really? How can these models help me mitigate risk, more accurately predict outcomes, identify hidden intellectual assets, and streamline business processes? Real questions, tough questions: fun challenges!
Schema.org has announced that GoodRelations is now fully integrated into the markup vocabulary backed by Google, Yahoo!, Bing/Microsoft, and Yandex (read our past schema.org coverage). GoodRelations is the e-commerce vocabulary that has been developed and maintained by Martin Hepp since 2002 (previous coverage).
In the official announcement, R.V. Guha (Google) says, “Effective immediately, the GoodRelations vocabulary (http://purl.org/
Dan Brickley announced today that schema.org has added the property “additionalType” to the basic building block, schema.org/Thing. As Brickley says, “The additionalType property makes it possible for Microdata-based publishers to list several relevant types, even when the types are from diverse, independent schemas. This is important for schema.org as it allows our markup to be mixed with other systems, without making it too hard for consuming applications to interpret. A description can use a schema.org type as a base, but mention others (e.g. from DBpedia, Freebase, eventually Wikidata…) to improve the specificity and detail of the description.”
As RDFa already allows for use of multiple vocabularies (through the ‘typeOf’ attribute), it is recommended that RDFa publishers use that native syntax.
A call for comments is out for a proposal for a ‘Datasets‘ addition to schema.org, via the W3C’s Web Schemas task force group that is used by the schema.org project to collaborate with the wider community.
The proposal extending schema.org for describing datasets and data catalogs introduces three new types, with associated properties, as follows:
Writing at the Schema.org blog, Dan Brickley calls it a “small but useful vocabulary,” with particular relevance to open government and public sector data.
Dan Brickley has posted a great article on the Schema.org blog commenting on some major developments surrounding schema.org. He writes, “Schema.org was launched a year ago. This week several of the schema.org team returned to the SemTechBiz conference for a panel to discuss where we are, and where we’re going. Schema.org is all about shared vocabulary, rather than any specific markup encoding. As we reported last year, the RDFa Working Group have been working hard to address feedback from schema.org and others. Yesterday’s panel gave us the chance to be the first to welcome W3C’s announcement that RDFa 1.1 is now a full W3C recommendation. This new standard, in particular the RDFa Lite specification, brings together the simplicity of Microdata with improved support for using multiple schemas together.” Read more
A packed room at the Semantic Tech & Business Conference in San Francisco played host to the much-anticipated Schema.org panel on Wednesday morning. As W3C semantic activity lead and moderator Ivan Herman had hoped (see this article), the discussion didn’t get bogged down in a duel between RDFa and microdata, but rather emphasized some important accomplishments of the last year and looked forward to future work.
As Herman put it, the only discussion he wanted to have around RDFa was to announce that the proposed RDFa 1.1 recommendations are expected to be published as official W3C standards Thursday, and that there had been a lot of interaction with the schema.org folks to make this useable for them as well.
Wednesday’s panel was composed of: Dan Brickley, of Schema.org at Google; R.V. Guha of Google; Steve Macbeth of Microsoft; Peter Mika ofYahoo!; Jeffrey W. Preston of Disney Interactive Media Group; Evan Sandhaus of The New York Times Company; and Alexander Shubin of Yandex.
