The cargo vessel Plassey ran on rocks off Inisheer in a storm in March 1960. The crew was saved by the islanders. Subsequent storms pushed her onto higher ground and broke her back. This is the shipwreck that's seen in the opening credits of “Father Ted.” The world-famous Cliffs of Moher are located just opposite the South Sound, 10km away.

(I'm new to this Google Plus thing.)

I've been thinking a lot about microdata lately. One of the things that bothers me: microdata very much encourages authors to use a single vocabulary. Combining vocabularies is difficult and often requires repeating content. This drives authors to schema.org because it is the one vocabulary that Google supports.

Schema.org is a closed, proprietary play. It is unclear how design decisions are made, who decides about extensions and changes, what one would have to do to get one's input listened to.

But because of Google's market power and the single-vocabulary issue, others don't even need to bother trying to define new vocabularies overlapping with schema.org. It's hard to see how other, better or more open, community-based alternatives like microformats could ever develop.

So I wrote a blog post today about how microdata could be extended to better support multiple vocabularies. It's not as simple as I'd like; I can definitely appreciate the technical reasons for restricting microdata to a single vocabulary per scope … Anyway, the link is below.

Yes, I can see why that would seem a bit silly from an RDF perspective. However, simply resolving the property against the itemtype and getting things like http://schema.org/name doesn't really work either. There's no machine-checkable restriction one could make on itemtype to ensure that http://schema.org/name doesn't conflict with another type.

It also seem dubious to assume that same-name properties on types http://example.com/T1 and http://example.com/T2 always mean the same thing.

D2RQ v0.8 released! New features include preliminary SPARQL 1.1 support, Firebird support, generation of RDFS/OWL schemas for databases, and download maps for making the content of CLOB/BLOB columns accessible via HTTP. Datatype compatibility with Oracle, MySQL, SQL Server and HSQLDB has been greatly improved, and a truckload of bugs has been fixed.

+Richard Cyganiak , after a little digging I found that D2RQ_ROOT=${0%/*} was not pointing to the correct folder. Changing to the absolute path solved the problem. Thanks

I'm hereby coining a new term: A “*triple tar-pit*” is an RDF representation of some data that makes it really hard to do basic operations on that data.

Examples:

* RDF Reification,
* SCOVO,
* the rdfabout.com U.S. Census dataset.

Loosely based on this quote:

“Beware of the Turing tar-pit in which everything is possible but nothing of interest is easy.” —Alan Perlis
