Additions to the MARC Code Lists for Relators, Sources, Description

The code listed below has been recently approved for use in MARC 21 records. The code will be added to the online MARC Code Lists for Relators, Sources, Description Conventions.

The code should not be used in exchange records until after November 13, 2007. This 60-day waiting period is required to provide MARC 21 implementers time to include newly defined codes in any validation tables they may apply to the MARC fields where the codes are used. (Description Conventions)

The following code is for use in subfield $2 in field 040 in Bibliographic and Authority records (Description Conventions).

W3C Completes Bridge Between HTML/Microformats and Semantic Web

Big news from the W3C, GRDDL.
Today, the World Wide Web Consortium completed an important link between Semantic Web and microformats communities. With "Gleaning Resource Descriptions from Dialects of Languages", or GRDDL (pronounced "griddle"), software can automatically extract information from structured Web pages to make it part of the Semantic Web. Those accustomed to expressing structured data with microformats in XHTML can thus increase the value of their existing data by porting it to the Semantic Web, at very low cost.

"Sometimes one line of code can make a world of difference," said Tim Berners-Lee, W3C Director. "Just as stylesheets make Web pages more readable to people, GRDDL makes Web pages, microformat tags, XML documents, and data more readable to Semantic Web applications, opening more data to new possibilities and creative reuse."

Library Card Sign-up Month

September is Library Card Sign-up Month. It is also library card renewal month at MPOW, the Lunar and Planetary Institute. In my latest podcast I used the 10 second clip from ALA to reinforce the renewal message. (I felt like a sound engineer getting it the right volume and speed.) They have other lengths that might meet your needs better. Thanks ALA.

Web Ontology Language (OWL)

HP labs has a new report on OWL, Comparing OWL Semantics Turner, David; Carroll, Jeremy J. HPL-2007-146
The OWL Web Ontology Language is endowed with two model theories, reflecting its origins as a compromise between two different communities. By design these model theories give rise to very similar semantics, and a precise statement of the correspondence between the model theories is conjectured with a sketch proof at the end of the OWL semantics specification document. We have filled in the details of this sketch proof using the Isabelle/HOL proof assistant, and developed machinery for further study of the formal semantics of OWL. Our study was sufficiently detailed to find a handful of minor errors in the specification of the semantics of OWL that previous work had overlooked. We also sought a stronger result by showing a partial converse to the known correspondence, but it proved impossible to achieve this within our time constraints; instead we conjecture a possible method for strengthening the correspondence.

OK Training

We invite you to participate in Mars In and Out. A free NASA-supported workshop designed to bring earth and space science into your library and after-school children’s and community programs November 8 and 9, 2007.

The Office of Library Development
Oklahoma Department of Libraries
200 NE 18th Street
Oklahoma City, Oklahoma 73105

Mars Inside and Out! will acquaint you with everything you need to know about the mysterious red planet to bring exciting programs to your community. You will learn about how the Martian environment has changed through time, the possibility for life on Mars, past, present, and future NASA missions to Mars, and plans and challenges for having humans living and working on Mars.

Scientists and educators from the Lunar and Planetary Institute will share space science information, resources, hands-on activities, and demonstrations developed specifically for librarians and after-school program providers to infuse into their programs with children ages 8 to 13 and their families.

During the workshop you will:

  • Meet NASA scientists and engineers involved in Mars exploration
  • Learn about Mars science, missions, and future exploration
  • Receive training in related hands-on science inquiry activities, designed for children ages 8 to 13
  • Receive related resources and materials that you can use in your programs
  • Explore ideas for presenting space science programs to young audiences and to other colleagues
  • Collaborate with other after-school program providers and children’s and youth librarians in Oklahoma and become part of the growing Explore! community
  • Receive a $100 stipend for attending!
The workshop is free. You will receive Mars Inside and Out! presentations, activities, and resources (posters, book lists, suggested Web sites), and the first 25 participants to register will receive a $100 stipend for completing the workshop. The materials are ready to be incorporated into your existing children’s and youth programs.

But wait — there’s more! You will also receive materials for ten additional Explore! space science topics (rockets, space stations, space colonies, egg-stronauts, solar system, shaping the planets, comets, staying healthy in space, and the Sun-Earth connection). Each of these topics has complementary hands-on activities and resources that can be found on the Explore! website.

The workshop begins at 9:00 am on Thursday, November 8, and continues until the close of the day, 5:00 pm, on Friday, November 9. Light breakfasts, lunches, and afternoon snacks will be provided and, of course, chocolate will be available, too! Participants are responsible for travel, housing, and dinner costs, and all logistical arrangements.

Space is limited; please register by 5 October to reserve your place in the workshop. Come join us for a fun-filled and learning-filled two days. We look forward to exploring Mars Inside and Out! with you. Drop me a request for a registration form.
