Happy Holidays

Merry Christmas and Happy Hanukkah. I'll be back Tuesday.

LPI Podcast

Last night I submitted the LPI podcast to iTunes. The submission seemed to go fine, the metadata was read and the RSS feed acceptable. They have a review process, so now I'm waiting to see if it will be accepted. Anyone have any idea how long it takes?

I've also just learned about high and low pass filters. I've been using noise reduction and volume normalization, these are some more tools to add to the mix. I'll be using them on my next podcast, sometime next year.

Learning Object Metadata

The latest issue of Interdisciplinary Journal of Knowledge and Learning Objects has some interesting articles.

Tree View Editing Learning Object Metadata by Zeynel Cebeci and Yoldas Erdogan.

This paper introduces and examines an authoring tool called as TreeLom for producing the metadata compatible to IEEE LOM draft standard. TreeLom, has been developed with MS .NET framework technology, is an application of XML binding of the LOM. Its tree view editing interface provides rapid data input in building learning object metadata.
A Framework for Metadata Creation Tools by Valentina Malaxa and Ian Douglas
Metadata is an increasingly important aspect of resource discovery. Good metadata has the potential to increase discovery and reuse and to facilitate interoperability of digital assets. Using the domain of learning objects, issues associated with the application of metadata standards and the challenges in metadata creation are examined. A framework for customizable metadata authoring that addresses the issues and challenges is described. The framework consists of flexible metadata schema, metadata schema views, templates, collaborative metadata editing, contextual help, and an effective interface component selection. A prototype implementation of the framework, CLOMAT (Customizable Learning Objects Metadata Authoring Tool), is used to illustrate the framework in operation. An initial evaluation of this prototype indicates substantial productivity gains over conventional metadata creation tools.

MarcOnt Ontology

Some interesting work being done by the MarcOnt initiative.
With the Semantic Web emerged the Dublin Core Metadata standard for library resource description. Besides the fact that most of the information covered by MARC21 is lost, the full potential of the Semantic Web is not being used. It still seems to be the best core ontology for L2L communication.

However MarcOnt ontology, is based on a social agreement that will combine descriptions from MARC21 together with DublinCore and makes use of the full potential of the Semantic Web technologies. This will include translations to/from other ontologies, better support for L2L, more efficient searching for resources (i.e. users may have impact on the searching process).


The following paper is available for review by the MARC community:Several discussion papers and a draft agenda will be distributed shortly.

These will be discussed at the meetings of the MARC Advisory Committee at Midwinter ALA in San Antonio on Jan. 21-22, 2006.

Support Texas School Libraries

School libraries and school librarians are in an extremely vulnerable position right now. They need your help, your voice, and the voices of your library’s supporters to let the lawmakers know that the education of our children will be irreparably harmed if school libraries are forced to close, if schools administrators decide they can “do without” school librarians, or if school libraries wither away for lack of funding. All of these scenarios are possible if the proposed 65% rule passes, using the federal guidelines that exclude libraries (but include sports) in the definition of “classroom instruction.”

The vast majority of people, whether they are parents, teachers or persons with no personal stake in local schools, are shocked and outraged when they learn that school libraries might not be considered instructional elements of education. School libraries support classroom instruction, and school librarians teach students skills that will be critical throughout their educations.

They are asking you to do at least one of these four things to help save Texas school librarians and school libraries.

  1. Email your state representative, senator, and State Board of Education member. It’s easy. Find the contact information for your elected officials.
  2. Ask three people-such as the chair of your local PTA or friends group, a teacher, community and business leaders-to support this effort by emailing, contacting their representatives, or writing a letter to the editor of their paper.
  3. Write a letter to the editor of your local newspaper. Talking points and suggested instructions (65% letter to the editor campaign).
  4. Schedule an editorial board meeting with your local newspaper. Ask the newspaper to write an editorial advocating for school libraries to be included in the definition as “instructional.” See talking points and background information. Get instructions on setting up an editorial board meeting.


An assessment of RDF/OWL modelling by Dave Reynolds, Carol Thompson, Jishnu Mukerji, and Derek Coleman is a recent HP Labs tech report.
The Semantic Web initiative offers a set of standards (RDF, RDFS and OWL) for the representation and exchange of information. We address the question of what sorts of modelling problems these standards can be most fruitfully applied to. What benefits can be gained from using them? What are the costs and trade-offs involved? We use some simplified examples drawn from work exploring the use of RDF/OWL within a systems management setting but the overall discussion should be relevant to a broad range of potential RDF/OWL applications. We do not assume in depth knowledge of the RDF and OWL standards and include a summary of their main features in order to make the discussion accessible.

Midwinter MARBI Meeting

The following papers are available for review by the MARC community:Other papers and a draft agenda will be distributed shortly. The MARC Advisory Committee will meet to discuss these at Midwinter ALA in San Antonio at the following times:
Sat., Jan. 21 10:30-12:30
Sun., Jan. 22 1:30-3:30 and 4:00-6:00
There will not be a Monday afternoon meeting.

OAI-PMH Overlays

The Masters thesis by Magnus Enger, The concept of 'overlay' in relation to the Open Archives Initiative Protocol for Metadata Harvesting (OAI-PMH) is avilable via E-LIS.
The evolution of scholarly documentation is discussed in light of the theory of the "ecology of documentation". The OAI-PMH is presented, and a survey of features found in existing service providers/overlays is presented. A prototype overlay incorporating features of wikis and "tagging" is presented along with some thoughts on how overlays may evolve and differentiate in the future.
It is a 102 page PDF file. Seen on the Scholarly Electronic Publishing Weblog

NLM Authority File

NLM has announced the implementation of a new authority index feature in the NLM Catalog. This feature provides access to an index of full author names (including dates and name qualifiers), organizations, and conference names, as well as series titles, associated with the bibliographic records in the NLM Catalog.
The authority index also offers added value by incorporating rich cross-reference entries for variant forms of names and titles that lead the user from a raw, initial search to the established form used on bibliographic records in the NLM Catalog. It also supports searching of names that may have changed over time, providing links to other and historical names used by authors or organizations, and to conference names and series titles that have changed numerous times. For series titles, additional information regarding NLM bibliographic treatment of that series is also provided.
