The highlights of the past week are around publishing — first with a model proposed by Eric Hellman in which consumers can pool enough money to pay publishers to “set a book free” under a Creative Commons license, then with an announcement by the University of Pittsburgh offering free hosting of open access e-journals. Since we have to be able to describe and find this content, their bibliographic descriptions are important; John Wilkin proposes a model for open access to elements of bibliographic descriptions. Rounding out this week’s topics are a report of a master’s degree program in business using Facebook, and tips for planning an unconference meeting.

MARC isn’t Dead, but it is a Dead End

This week I sat in on the first of the three “Using RDA: Moving into the Metadata Future” webinars being hosted by ALA. This one was hosted by Karen Coyle with the title New Models of Metadata where she talked about library-specific efforts such asRDA and FRBR as well as the linked data effort in the wider world of information. There was a great deal of concern expressed in the chat window by participants about the future of cataloging, of cataloguers, and of MARC. The latter brought up memories of Roy Tennant‘s “MARC Must Die” declaration. My take away, though, isn’t that MARC is dead as much as MARC is a dead end.

Google Search Engine Adds Support for RDFa, Or Do They?

Via a post and an interview on the O’Reilly Radar blog, Google announced limited support for parsing RDFa statements and microformat properties in web page HTML coding and using those statements to enhance the relevance of search results as so-called “rich snippets”. In looking at the example review markup outlined in the O’Reilly post, though, I was struck by some unusual and unexpected markup. Specifically, that the namespace was this http://rdf.data-vocabulary.org/ thing that I had never seen before, and the “rating” property didn’t have any corresponding range that would make that numeric value useful in a computational sense.

PHP Script for hCalendar to iCalendar Conversion

I try to do the “right thing” in postings on DLTJ. In the context of this discussion “right” is an attempt to be progressive: including hCalendar microformat markup for postings that include mention of events. The latest example of this was yesterday’s posting of the Learning, Libraries and Technology Conference. Embedded in the first paragraph is markup that another application reading the DLTJ feed can use to understand that the posting is talking about an event. (The Technorati Events” service is one example.) The key parts of the HTML are bolded below:

Would the Real “Dublin Core” Please Stand Up?

I’ve been following the discussion by Stu Weibel on his blog about the relationship between Resource Description Framework (RDF) and Dublin Core Abstract Model (DCAM), and I think I’m as confused as ever. It comes as a two part posting with comments by Andy Powell Pete Johnston (apologies, Pete), Mikael Nilsson, Jonathan Rochkind, and Ed Summers. Jonathan’s and Ed’s comments describe the same knowledge black hole that I’ve been facing as well; in Ed’s words: “The vocabulary I get–the DCAM is a tougher nut for me to crack.”
