The Web Is 25 — And The Semantic Web Has Been An Important Part Of It

web25NOTE: This post was updated at 5:40pm ET.

Today the Web celebrates its 25th birthday, and we celebrate the Semantic Web’s role in that milestone. And what a milestone it is: As of this month, the Indexed Web contains at least 2.31 billion pages, according to WorldWideWebSize.  

The Semantic Web Blog reached out to the World Wide Web Consortium’s current and former semantic leads to get their perspective on the roads The Semantic Web has traveled and the value it has so far brought to the Web’s table: Phil Archer, W3C Data Activity Lead coordinating work on the Semantic Web and related technologies; Ivan Herman, who last year transitioned roles at the W3C from Semantic Activity Lead to Digital Publishing Activity Lead; and Eric Miller, co-founder and president of Zepheira and the leader of the Semantic Web Initiative at the W3C until 2007.

While The Semantic Web came to the attention of the wider public in 2001, with the publication in The Scientific American of The Semantic Web by Tim Berners-Lee, James Hendler and Ora Lassila, Archer points out that “one could argue that the Semantic Web is 25 years old,” too. He cites Berners-Lee’s March 1989 paper, Information Management: A Proposal, that includes a diagram that shows relationships that are immediately recognizable as triples. “That’s how Tim envisaged it from Day 1,” Archer says.

Case Study Radio, Ep. 1: Business Value of Linked Data - Case Study Radio today is launching a new podcast series, “Case Study Radio,” that focuses on stories of applications of Semantic Technologies. Our first episode, sponsored by Zepheira, features a conversation with Dr. Eric Miller.

During our 14 minute discussion, we briefly talk about “What is Linked Data,” and then quickly move on to discuss the nature of Linked Data and the general business value to organizations that have taken Linked Data approaches. Dr. Miller mentions several high-profile, successful implementations, and in future episodes, we will take a deeper look at similar case studies.

OCLC Announcement: Meets (and hints of more to come)

image of library from Shutterstock.comOCLC has announced that pages now include descriptive mark-up.

Created over the last four decades with the participation of thousands of member libraries, WorldCat is the world’s largest online registry of library collections. As the official press release states, “ now offers the largest set of linked bibliographic data on the Web. With the addition of mark-up to all book, journal and other bibliographic resources in, the entire publicly available version of WorldCat is now available for use by intelligent Web crawlers, like Google and Bing, that can make use of this metadata in search indexes and other applications.”

On the heels of the announcement earlier this week about Dewey Decimal Classifications also being available as Linked Data, this certainly marks an exciting week in the world of library information and the Semantic Web. However, this should also prove to be exciting for non-librarians, as these resources are now available beyond the world of library sciences.

Exhibit 3.0 Part 1 – An Open Source Software Platform for Publishing Linked Data

This is Part I of a two-part series. Part II will be published later this month.

Individuals, communities and organizations increasingly require the ability to combine fragmented data sources into easily searched and navigated wholes.  From combining family playlists to merging scientific databases and spreadsheets, the need for integrating data and metadata from multiple sources into a single, Web-based publishing framework is increasing.  Allowing users to publish, explore and visualize data in useful ways is a powerful mechanism for identifying, organizing and sharing patterns inherent in this data.  Web data publishing demands easier data integration and customizable ways to interact with the data such as faceted browsing, spatial or temporal-based visualizations, tag clouds, and full-text search.

Looking Ahead to SemTech

On Saturday, I once again board a plane from London to San Francisco; the first of two trips to the city in June, and my fourth (or possibly fifth?) time attending the Semantic Technology Conference.

The conference itself is in its seventh year, and now seems settled into its San Francisco home after a number of years further down the Bay in San Jose. As in previous years, the programme is rich, varied, and packed with so many parallel tracks that it can at first seem daunting for both newcomers and old hands alike. In a bid to make things a bit easier for people, we’re gathering the friendly team from the monthly Semantic Link podcast, and sticking them up on stage on Sunday evening to pick out their highlights for the week ahead. I’m sure they’ll also offer hints and tips for navigating the corridors and session rooms, and possibly even flag up the best of the secret roof-top parties. Read more

Developing Semantic Web Applications: Current Tools, Best Practices and Future Directions

The Semantic Web is nearing the point of widespread practical adoption:

• The core specifications have stabilized

• Tools and frameworks implementing key features have been through several development cycles

• An increasing number of major software companies have developed semantically enabled products or are actively researching the space

As companies start to translate theory into real applications, they are confronted with a host of practical software engineering issues:

• What is the standard or recommended functional architecture of a semantic application?

• How does that architecture relate to the Semantic Web standards?

• Which of those standards are stable and which can be expected to evolve in ways that would significantly impact prior applications?

• What types of tools/frameworks exist that can be leveraged to help implement semantic applications?

• How mature are the various categories of Semantic Web tools/frameworks?

• Can API standardization be expected for certain tool/framework categories?

• What best practices exist for the design, implementation and deployment of semantic applications?

• What future trends in support for semantic application development can be expected?

This panel session gathers together semantics experts from the software industry to address these and other practical issues relating to the development of semantic applications.

Dublin Core and OWL

Dublin Core and OWL

We’ve known about the Dublin Core ( ) pretty much forever. We know it has a following in Library Science and content management systems, and Adobe uses their tags as the basis for the XMP ( And we knew that at least one of the original architects for the Dublin Core, Eric Miller (, is now deeply invested in the Semantic Web.
So, we knew it was just a matter of time until we came to a client who was implementing a content management system using the Dublin Core tags and who wanted to integrate that with their Enterprise Ontology.
We just assumed there was a Dublin Core OWL implementation just for this purpose. If there is, it’s pretty well hidden. (One of my motivations in writing this blog is to see if this brings it out of the woodwork). The obvious one (the one that comes up first in a Google search) is from Stanford  ( On closer inspection, the only OWL property used in this ontology is the owl:annotationProperty (comment). The rest of it is really just naming the tags and providing the human readable definitions. But this isn’t really helpful for integration.
It turns out there are several other problems with the Dublin Core for this type of usage. For instance, the preferred usage of the “creator” tag is a LastName, FirstName literal. LastName, FirstName is pretty ambiguous. There are a lot of “Smith, John”s in most corporate databases. And in many cases we know much more precisely (to the urn: level) which John Smith we’re dealing with when we capture the document.
So, we ended up, I’m sure, re-inventing the wheel. We have built an OWL version of the Dublin Core suitable for integration with Enterprise Ontologies. I’m on the road again starting tomorrow, but within a week or two we expect to have it vetted and out in a suitable public place. In the next installment I’ll go over some of the design tradeoffs we made along the way. By the way, what suitable public places are people going to for their ontologies these days?

Breaking into the Semantic Web, Part II

This interview with Eric Miller, President of Zepheira was conducted by Golda Velez.

SR: Eric, let me ask your advice. The Semantic Web is interesting, exciting, promising. So say I’m a developer, how do I get involved with it? Or suppose I have a tech company, how do I get work in this field?
