You Can Take An Active Role In Schema.Org

brickHave you wanted to get involved in the schema.org project? Your contribution to the collaborative effort driven by Bing, Google, Yahoo and Yandex for a shared markup vocabulary for web pages is more than welcome. As Dan Brickley, who is developer advocate at Google, noted during his presentation about schema.org’s progress to date at this summer’s Semantic Technology & Business Conference, the “pattern of collaboration with the project [is] we’re trying to push work off on people who are better qualified to do it, and then we mush it all together.”

What is meant by that is that the project is so broad, covering such a huge amount of topics, that the input of experts – whether from the library, media, sports or any other of the multitude of communities whose vocabularies are or aim to be represented – is incredibly valuable, and very much encouraged. In an overview of the 2013-2014 releases, which included TV/radio, civic services, and bibliographic additions, as well as accessibility properties, among others, Brickley related that during the year, “We listened a lot. We listened to people who knew better than us about accessibility, about how broadcast TV and radio are described, about describing social services, about libraries, journals, and ecommerce, and then integrated their suggestions into a unified set of schemas.”

New Opps For Libraries And Vendors Open Up In BIBFRAME Transition

semtechbiz-10th-125sqOpportunities are opening up in the library sector, both for the institutions themselves and providers whose solutions and services can expand in that direction.

These vistas will be explored in a session hosted by Kevin Ford, digital project coordinator at the Library of Congress at next week’s Semantic Technology & Business conference in San Jose. The door is being opened by the Bibliographic Framework Initiative (BIBFRAME) that the LOC launched a few years ago. Libraries will be moving from the MARC standards, their lingua franca for representing and communicating bibliographic and related information in machine-readable form, to BIBFRAME, which models bibliographic data in RDF using semantic technologies.

WorldCat Releases 197 Million Nuggets of Linked Data

worldcatRichard Wallis of OCLC reports on his Data Liberate blog, “A couple of months back I spoke about the preview release of Works data from WorldCat.org.  Today OCLC published a press release announcing the official release of 197 million descriptions of bibliographic Works. A Work is a high-level description of a resource, containing information such as author, name, descriptions, subjects etc., common to all editions of the work.  The description format is based upon some of the properties defined by the CreativeWork type from the Schema.org vocabulary.  In the case of a WorldCat Work description, it also contains [Linked Data] links to individual, OCLC numbered, editions already shared from WorldCat.org.” Read more

194 Million Linked Open Data Bibliographic Work Descriptions Released by OCLC

OCLC WorldCat logoYesterday, Richard Wallis gave a peek into some exciting new developments in the OCLC’s Linked Open Data (LOD) efforts.  While these have not yet been formally announced by OCLC, they represent significant advancements in WorldCat LOD. Our reporting to date on LOD at WorldCat is here.

Most significantly, OCLC has now released 194 Million Linked Open Data Bibliographic Work descriptions. According to Wallis, “A Work is a high-level description of a resource, containing information such as author, name, descriptions, subjects etc., common to all editions of the work.” In his post, he uses the example of “Zen and the Art of Motorcycle Maintenance” as a Work.

Video: Shared Library Data at the ALA Annual 2013

Logo of the OCLCRegular readers of this blog may know that Linked Data and Semantic Web technologies are gaining significant traction in the worlds of Libraries, Archives, and Museums. Earlier this summer, Richard Wallis (Technology Evangelist) and Ted Fons (Executive Director, Data Services and WorldCat Quality) of the OCLC discussed and demonstrated how that organization in particular is sharing library data. This presentation was delivered at the Annual Conference of the American Libraries Association in Chicago.

The presentations by Fons and Wallis serve as good introductory pieces to practical Linked Data use, and the potential benefits of using Linked Data as a platform for knowledge management for large collections of data.  Wallis also discusses why OCLC chose to use schema.org as a vocabulary.

Ready, Set, Lightning! 5-Minute Talks at SemTechBiz — Part 2

During the recent Semantic Technology and Business Conference in San Francisco, a motley crew of expert presenters got up in front of a packed room, took a deep breath, and spoke passionately about the semantic projects nearest and dearest to their hearts while the unforgiving clock ticked their five precious minutes away. At the conference I shared highlights from some of those aptly named Lightning Sessions. Here are a few more snappy sessions that captivated the room that day:

Semantic Technology to Shed Light on Big Dark Data with Ben Zamanzadeh, DataPop

DataPop is a startup in the field of semantic advertising. The company seeks to create actionable insights for clients with semantics. As Ben put it, “Ad data is still dark data. Consumer actions are very hard to understand and even harder to predict.” The talk description explains DataPop’s approach: “DataPop’s Semantic Advertising Technology uses Machine Learned Semantic Models to build and analyze advertising campaigns that surpasses conventional advertising capabilities. Composite Semantic Data Models are used to translate Big piles of Data into meaningful entities, then Inference Engines transcribe information such that decisions and strategies can be formed. Semantic Methods has made it possible for us to explain the reasoning behind ‘why’ things happen.” Read more

Libraries: Time To Take Your Place On The Web Of Data

At The Semantic Technology and Business conference in San Francisco Monday, OCLC technology evangelist Richard Wallis broke the news that Content-negotiation was implemented for the publication of Linked Data for WorldCat resources. Last June, WorldCat.org began publishing Linked Data for its bibliographic treasure trove, a global catalog of more than 290 million library records and some 2 billion holdings, leveraging schema.org to describe the assets.

“Now you can use standard Linked Data technologies to bring back information in RDF/ XML, JSON, or Turtle,” Wallis said. Or triples. “People can start playing with this today.” As he writes in his blog discussing the news, they can manually specify their preferred serialization format to work with or display, or do it from within a program by specifying to the http protocol for the format to accept from accessing the URI.

“Two hundred ninety million records on the web of Linked Data is a pretty good chunk of stuff when you start talking content negotiation,” Wallis told the Semantic Web Blog.

The Future of Libraries, Linked Data and Schema.Org Extensions

Yesterday The Semantic Link Podcast featured Karen Coyle, a consultant in library technology who’s consulted for esteemed institutions including the Library of Congress. Coyle discussed libraries’ long history with metadata, including with the MARC (machine-readable cataloging) format for nearly 50 years, and of sharing that metadata. That history helps explain why libraries, she said, are looking at semantic web technology – but also why changes to established processes are huge undertakings. “The move toward Linked Data will be the most significant change in library data in these two centuries,” she said, requiring the move from mainly textual data into using identifiers for things and data instead of strings.

Today, The Semantic Web Blog continues the discussion by sharing some perspectives on the topic from OCLC technology evangelist Richard Wallis. As noted in yesterday’s podcast, change has its challenges. “Getting the library community to get its head around Linked Data as a replacement for MARC … will be a bit of a challenge,” Wallis says. While more members of the library community are starting to “get” Linked Data, and what can be accomplished by extracting entities and linking between them, some still struggle with why change can’t just occur within the MARC format itself or its successor Resource Description and Access (RDA), that provides atomistic, machine-actionable data and machine-interpretable relationships. RDA, Wallis reminds us, took a decade from inception to publication and business model.

“The ramifications of turning into the Linked Data world are quite deep and meaningful but it will be a few years for that to be established in the library world,” Wallis says.

Schema.org and Libraries: Coming to a Consensus

Richard Wallis of DataLiberate recently wrote, “Back in September I formed a W3C Group – Schema Bib Extend.  To quote an old friend of mine ‘Why did you go and do that then?‘  Well, as I have mentioned before Schema.org has become a bit of a success story for structured data on the web.  I would have no hesitation in recommending it as a starting point for anyone, in any sector, wanting to share structured data on the web.  This is what OCLC did in the initial exercise to publish the 270+ million resources in WorldCat.org as Linked Data. At the same time, I believe that summer 2012 was a bit of a watershed for Linked Data in the library world.  Over the preceding few years we have had various national libraries publishing linked data (British LibraryBibliothèque nationale de FranceDeutsche National BibliothekNational Library of Sweden, to name just a few).  Read more

Step-by-Step: Putting WorldCat Data Into Triple Stores

Richard Wallis has followed up his recent announcement that WorldCat data can now be downloaded as RDF triples with an explanation of how to put that data into a triple store. He begins: “Step 1: Choose a triplestore.  I followed my own advise and chose 4Store.  The main reasons for this choice were that it is open source yet comes from an environment where it was the base platform for a successful commercial business, so it should work.  Also in my years rattling around the semantic web world, 4Store has always been one of those tools that seemed to be on everyone’s recommendation list.” Read more
