PURLs

PURLZ Server version 1.2 has been released.

Purlz are Web addresses or Uniform Resource Locators (URLs) that act as permanent identifiers in the face of a dynamic and changing Web infrastructure. Instead of resolving directly to Web resources, PURLs provide a level of indirection that allows the underlying Web addresses of resources to change over time without negatively affecting systems that depend on them. This capability provides continuity of references to network resources that may migrate from machine to machine for business, social or technical reasons.

Nature Now has XMP

Nature now includes XMP semantic data in the PDF version of their articles.

We now have a complete bibliographic record (including DOI) embedded in the PDF using structured markup. And, moreover, we also have a solid bedrock for adding in any additional metadata should the need arise. This semantic labelling is available on all new issues of Nature and will be added to other NPG titles over the coming months.

XMP as a labelling technology could well go a long way towards addressing concerns raised by Olivia Judson in an op-ed piece earlier this week in the New York Times: Defeating Bedlam. The author decries that "downloading papers from journal Web sites" means that "access to information is easier and faster than ever before ... but there’s been no obvious way to manage it once you’ve got it." Those days may soon be over.

Now with XMP all manner of scholarly content - documents, images and other media types - can be properly labelled and many programs (not just Zotero and Papers which she reviews) can directly profit from the richness of semantic web descriptions.

Timeline and Plan for the Next Five Library of Congress Genre/Form Projects

News from LC.

In July, 2008, the Library of Congress Acquisitions and Bibliographic Access (ABA) management team approved five new genre/form projects to be undertaken by the Cataloging Policy and Support Office (now the Policy and Standards Division): cartography, law, literature, music, and religion. On October 31st, 2008, the Division presented its timeline and plan for those projects to the ABA management team, and it was approved on November 17th.

The plan follows the principles and recommendations for the management of the genre/form projects, as outlined in the moving image project report; provides opportunities for involvement by other libraries and organizations with an interest in genre/form headings; requests input from the broader library community at various points in each project; and, furnishes a timeline that will allow for the orderly roll-out of genre/form headings in each of the five disciplines under development during the next four years.
