Link credit goes to Joho. This looks pretty significant. The AZ Supreme Court ruled that document metadata must be disclosed under existing public records law. This may start a chain reaction with other states following suit. With the movement toward open data including data.gov and the Federal Register, this fits in well. Quite often metadata…

A great introduction article. Maybe it’s just the crowd I hang with, but RDFa looks like it’s moving from trendy to serious tooling. -m
The new feature called rich snippets shows that SearchMonkey has caught the eye of the 800 pound gorilla. Many of the same microformats and RDF vocabularies are supported. It seems increasingly inevitable that RDFa will catch on, no matter what the HTML5 group thinks. -m
I’ve been experimenting with the preview version of Wolfram Alpha. It’s not like any current search engine because it’s not a search engine at all. Others have already written more eloquent things about it. The key feature of it is that it doesn’t just find information, it infers it on the fly. Take for exmple…
At least, that’s how I’ve summarized John Allsopp’s article on HTML5 semantics. -m
Mark Birbeck, Web Backplane. Problem statement: You shouldn’t have to “scrape” government sites. Solution: RDFa <div typeof=”arg:Vacancy”> Job title: <span property=”dc:title”>Assistant Officer</span> Description: <span property=”dc:description”>To analyse… </span> </div> This resolves to two full RDF triples. No separate feeds, uses existing publishing systems. Two of the most ambitious RDFa projects are taking place in the UK….
Ronald Reck, SAP; Kenneth Sall, SAIC “I wish I knew when people were saying bad things about me.” Sentiment analysis. Kapow used initially. From 800k news articles (from 1996 and 1997), extracted 450M RDF assertions. The 13 Reuters standard metadata elements not used in this case. Used Redland for heavy RDF lifting. Inxight ThingFinder (commercial)…
Haven’t mentioned here that RDFa is a W3C Recommendation. I’m thrilled that something that I’ve been thinking about for a while is ready for prime time. Also, as of this writing the first page of results at Google still prominently links to a terribly outdated draft of the spec. The first page of results at…
Native Germanic-language speaker: “What is your name?” Native Romance-language speaker: “How do you call yourself?” Native RDF speaker: “How do you call what your name is?” More collected Geek Thoughts at http://geekthoughts.info.
This post will be continuously updated to contain the most recent details about an XQuery 1.0 RDFa parser I wrote for Mark Logic. It follows the Functional RDFa pattern. At present there is little to say, but eventually code and more will be available. Stay tuned. -m
On the eRDF discussion posting, Toby Inkster, an implementer of eRDF, talks about why it’s bad to steal the id attribute, and why RDFa is better suited for general purpose metadata. Worth a read. -m
Through the weekend I put most of the final touches on an implementation of RDFa in XQuery. The implementation is based on the functional specification of RDFa, an offshoot of the excellent work coming out of the W3C task force. The spec contains a procedural description of the parsing algorithm, and several have successfully followed…
I haven’t seen an announcement about this, but try the following query on Yahoo Search: [searchmonkeyid:com.yahoo.rdf.rdfa] (link). It shows documents containing RDFa, with Digg at the top. Since this is a Searchmonkey ID, it’s also usable in Searchmonkey to actually extract the metadata and use it to customize search results. Does your site use RDFa…
The result of tons of work by lots of smart people. Go forth and implement. And I need to put in a plug for Metadata for Grandma which (indirectly, as it turned out) influenced the spec. RDFa is already a big deal, used in places like SearchMonkey. The subset of RDFa used by SearchMonkey is…
During a Q&A session today, I asked a panel of MarkLogic users about whether they saw metadata (and specifically RDF) as becoming an important factor in the near future. Fair enough question, having just come from the SearchMonkey project at Yahoo! The answer: A qualified yes. Having a strong metadata store and query engine isn’t…
