Open The Door To Bringing Linked Data To Real-World Projects

ld1Linked Data: Structured Data on the Web is now available in a soft-cover edition. The book, authored by David Wood, Marsha Zaidman, Luke Ruth, and Michael Hausenblas, and with a forward by Tim Berners-Lee, aims to give mainstream developers without previous experience with Linked Data practical techniques for integrating it into real-world projects, focusing on languages with which they’re likely to be familiar, such as JavaScript and Python.

Berners-Lee’s forward gets the ball rolling in a big way, making the case for Linked Data and its critical importance in the web ecosystem:“The Web of hypertext-linked documents is complemented by the very powerful Linked Web of Data.  Why linked?  Well, think of how the value of a Web page is very much a function of what it links to, as well as the inherent value of the information within the Web page. So it is — in a way even more so — also in the Semantic Web of Linked Data.  The data itself is valuable, but the links to other data make it much more so.”

The topic has clearly struck a nerve, Wood believes, noting that today we are “at a point where structured data on the web is getting tremendous play,” from Google’s Knowledge Graph to the Facebook Open Graph protocol, to the growing use of the vocabulary, to data still growing exponentially in the Linked Open Data Project, and more. “The industry is ready to talk about data and data processing in a way it never has been before,” he continues. There’s growing realization that Linked Data fits in with and nicely complements technologies in the data science realm, such as machine learning algorithms and Hadoop, such that “you can suddenly build things you never could before with a tiny team, and that’s pretty cool….No technology is sufficient in and of itself but combine them and you can do really powerful things.”

RDFa Fading Away in EPUB3 Standard

To follow up our story last week about the upcoming EPUB3 standard, for which International Digital Publishing Forum membership comments were due in by today, it appears that the updates “are moving the spec even further from any apparent support/use of RDFa.” That’s according to Eric Freese, solutions architect at digital publishing solutions vendor Aptara and member of the IDPF trade and standards organization.

One of the reasons RDFa support has been in question was that there were some concerns regarding what the future holds for RDFa 1.1. The timeline for RDFa 1.1 puts January 2012 as the date for the publication of all final documents. Issues such as its side-by-side evolution with microdata structured data markup schemes such as Google, Bing and Yahoo’s collaboration are still being reviewed, for example.

Upping the eBook Cool Factor

eBooks are cool, but they could get even cooler with EPUB3, the next version of the widely adopted distribution and interchange format for digital books (well, except for Amazon). The latest version of the standard could make it easier for publishers to more flexibly represent their offerings to digital book retailers, and add a lot of excitement to the eBook reading experience, too.

EPUB3 is based on HTML 5 and was proposed to include RDFa. RDFa is in question for eBook metadata now, however, though there is still the possibility to embed RDF/OWL within eBook content. (Membership comments on EPUB3 are due in by Aug. 22). EPUB 3 requires the same three metadata elements as EPUB 2, which are dc:identifier, dc:title, and dc:language, while also permitting many more. “We left it open to using something like RDFa so you can put in what you need to,” says Eric Freese, solutions architect at digital publishing solutions vendor Aptara. That could include, for example, using the PRISM (Publishing Requirements for Industry Standard Metadata) XML metadata vocabulary for managing and aggregating publishing content, or ONIX metadata for representing and communicating book industry product information.

However the RDFa question fares, one thing that is increasingly clear to publishers that have done any looking at all into eBooks, Freese says, is that “it doesn’t take long before they get hit in the face with the metadata problem. And as more time goes by there are fewer and fewer publishers who haven’t thought about doing eBooks.”
