EdNA Online: A Services-oriented Approach to Supporting E-Learning
The diagrams in this PowerPoint presentation are first rate as the content emphasises the design of the EdNA learning content repository system. The presentation argues that the EdNA system was based on learner needs and a subsequent business model, and this approach lead to the development of the resulting harvesting and content syndication service. I have commented before that EdNA has hit on the right model, and I say again, this is the right model. The syndication stuff is new (slide 13) and begins to show how learning resources can be effectively distributed into the community. More papers from the summit are available online.

vPreliminary LOM Survey
Ever wonder how people are actually using learning object metadata? This was the subject of a study conducted by Norm Friesen and Lassi Nirhamo over the summer and presented at the ADL Learning Repository Summit (the report is available from the SC36 WG4 Documents List. Though some things - such as the use of languagestrings - are working well, the vast majority of fields, especially educational metadata fields, are underused, and we are beginning to see promotional material creep into the description field. The best bit (though it's too small to appreciate) is a chart comparing a dozen or so different implementations of learning object metadata. In PowerPoint.

Transforming Metadata
This PowerPoint presentation, delivered at the ADL Repositories Summit a couple of weeks ago, surveys the process used by the Eisenhower National Clearinghouse to convert learning object metadata from the format harvested from the NSDL repository (using Open Archives Initiative (OAI) harvesting, in Dublin Core format) to its own version of the IEEE Learning Object Metadata format. This conversion is accomplished via what is called a 'crosswalk' (and that's your word for the day). The presentation is based on an article in D-Lib and is supported with reference documents describing the Crosswalks and the ENC Indexing Guidelines. Great stuff. By Kimberly S.

Rulemaking on Exemptions from Prohibition on Circumvention
Four new exemptions are added to the Digital Millennium Copyright Act (DMCA): lists of Internet locations blocked by filtering software, programs protected by dongles that prevent access due to malfunction or damage and which are obsolete, formats that have become obsolete and which require the original media or hardware, and access controls that prevent the enabling of the ebook's read-aloud function. Critics responded immediately (and correctly) that the vast majority of consumers are still unable to access their own property. By Librarian of Congress, October 28, 2003 [Refer][Research][Reflect]
