Problems with Microformats

This is old news, but new to me and maybe someone else. There are some basic problems with many of the microformats, including the hCalendar. The BBC has stopped using microformats.
Since /programmes first went live we've been working to ensure that programme data was accessible to people and machines alike. The API design was baked in at the application design stage. Similarly we've worked on adding microformats to HTML pages as a lightweight API. All broadcasts use the hCalendar microformat to add start times, end times, broadcast channels etc.

Unfortunately there have been a number of concerns over hCalendar's use of the abbreviation design pattern.

They were considering RDFa as an alternative.

So, does anyone know of any tools to easily create RDFa? Something to just plug in the info and have it pop out?

Name Authority Records

News form LC concerning Name Authority Records.
The Library of Congress is pleased to announce that OCLC has completed the pre-population of the NACO authority file with non-Latin references (authority 4XX fields) derived from non-Latin bibliographic heading fields in WorldCat, a use of data-mining techniques originally developed for the WorldCat Identities project. The pre-population project, which began in mid-July, added non-Latin script references to 497,576 name authority records for personal names and corporate bodies.

**For NACO catalogers, this means that the moratorium on updating 100/110 authority records that existed prior to July 2008 to add non-Latin script references is now lifted. All name authority records are now candidates for the addition of non-Latin script references. Thanks for your patience during this period.**

LC hopes to announce soon a process by which catalogers that have been examining the non-Latin script references added by this project can contribute to the development of policies and practices for the future, such as the issues raised in the white paper on non-Latin script references in name authority records.

Special thanks to Robert Bremer, and colleagues at OCLC, for all the efforts to make this pre-population a reality.

RDFa

Elias Torres, Ben Adida discuss RDFa on Technometria with Phil Windley
While the web is primarily for human consumption, more sites are including machine readable data. However, this information is usually included separately. As the RFDa Primer states, RFDa provides a set of XHTML attributes to augment visual data with machine-readable hints. RDFa helps bloggers and website authors make their web pages smarter by adding computer-readable information to a site. Elias Torres and Ben Adida talk about it, including its history and what problems RFDa is attempting to solve.

Torres and Adida also discuss the technical details of RDFa and give a detailed technical description of how RDFa works. They review the mechanics of RDFa and give examples of its usage.
