New Paper: Directly Mapping Relational Databases to RDF & OWL

Juan F. Sequeda, Marcelo Arenas, and Daniel P. Miranker have written a new paper entitled Directly Mapping Relational Databases to RDF and OWL. According to the abstract, “Mapping relational databases to RDF is a fundamental problem for the development of the Semantic Web. We present a solution, inspired by draft methods defined by the W3C where relational databases are directly mapped to RDF and OWL. Given a relational database schema and its integrity constraints, this direct mapping produces an OWL ontology, which, provides the basis for generating RDF instances. The semantics of this mapping is defined using Datalog.” Read more

White House Creates Blueprint for Consumer Privacy Bill of Rights

The Obama administration has announced a blueprint for a consumer privacy bill of rights. The President’s cover letter to the proposal stated, “Never has privacy been more important than today, in the age of the Internet, the World Wide Web and smart phones.  In just the last decade, the Internet has enabled a renewal of direct political engagement by citizens around the globe and an explosion of commerce and innovation creating jobs of the future. Much of this innovation is enabled by novel uses of personal information. So, it is incumbent on us to do what we have done throughout history: apply our timeless privacy values to the new technologies and circumstances of our times.” Read more

RDB2RDF Specifications Published by W3C

The W3C recently announced, “The RDB2RDF Working Group has published two Candidate Recommendation documents that help to bring relational database information to the Semantic Web: R2RML: RDB to RDF Mapping Language and A Direct Mapping of Relational Data to RDF.”

The announcement continues, “The former describes R2RML, a language for expressing customized mappings from relational databases to RDF datasets. Such mappings provide the ability to view existing relational data in the RDF data model, expressed in a structure and target vocabulary of the mapping author’s choice. The latter document defines a direct mapping from relational data to RDF. Implementations are invited. Read more

A Marriage Made For The Global, Digital Economy

At the recent SemTech Berlin conference, husband-and-wife team Michael Trevor McDonald and Kim Chandler McDonald, CTO and Executive VP, respectively, of KimmiC, led a session that discussed a marriage of a different sort: that between the Semantic Web and the user interface.  The session was described as providing the audience insight into the benefits of the semantic web, given that so much of the world’s economic brain/ecosystem is tied up in the relationships between companies, consumers and suppliers – an interaction between systems and people that is a real-life ‘Matrix’ whose ubiquity is hampered by the lack of a common way of talking about things such that they can be utilized and shared simply, and in a confidential, secure, and vendor-neutral manner.

The Semantic Web Blog had an opportunity to have an email discussion with the Australian-based minds behind KimmiC, and its FlatWorld cloud-based technology for enabling the global, digital economy, to learn more about the SemWeb/UI marriage.

Semantic Web Blog: Help us better understand this idea of The Matrix in the context described – considering the movie, is that a positive analogy and what does the Semantic Web have to do with it?

Michael: I think we can use the analogy pretty well as is. What we have seen in the market is essentially a few large companies trying to subvert the intent of the web into a controlled matrix (controlled by them) that they can exploit – it is, in fact, the cornerstone of their business models.

We view that consumers, once they become more aware of it, will see themselves as a “knowledge/insight” commodity in that they a) control their information and b) control who, when and where (what part) companies/friends/family etc. have access to them – it is most probably the next big frontier.

The Flap of a Butterfly Wing

Monarch Butterfly Danaus plexippus Male Yes you are right, one of the prime reasons for this post is an excuse to show some stunning pictures from nature.  However, there is also good reason to explore a Linked Data example, provided by Pete DeVries of the Department of Entomology at the University of Wisconsin – Madison, in his recent submission to the W3C public-lod mailing list.

Pete shows a good example of the benefits of Linked Data.  He provides links to information about the Monarch Butterfly (Danaus plexippus) from several Linked Data datasets, each of which provide different, but overlapping views.

Announcing PaySwarm Alpha for Developers

PaySwarm recently announced a new PaySwarm Alpha for developers (read our two part series about PaySwarm here). The article states, “This is a public sandbox — a developer test ground — that implements some of the newest PaySwarm REST API features.” It continues, “The biggest change was replacing the authentication mechanism that we were using for PaySwarm. We had implemented the system last year using the OAuth protocol only to find out that it made things more complicated than they need to be for the use cases that we were trying to cover. Some developers have asked why OAuth didn’t work for PaySwarm when it works for large sites like Facebook and Twitter.” Read more
