Not new, but something I've not mentioned before is DP9.
DP9 is a gateway service that enables indexing of an OAI data provider by an Internet search engine. DP9 does this by providing a persistent URL for repository records, and converting this to an OAI query against the appropriate repository when the URL is requested. This allows search engines that do not support the OAI protocol to index the "deep web" contained within OAI compliant repositories. We envision that similar gateway services for other protocols are promising to make a wide range of resources interopable with the web.The issue of Library hi tech on OAI reminded me of this tool.

The latest issue of Library hi tech is devoted to the Open Archives Initiative. Some of the articles are:
- The making of the Open Archives Initiative Protocol for Metadata Harvesting by Carl Lagoze; Herbert Van de Sompel OAI and NASA's scientific and technical information by Michael L Nelson; Terry L Harrison; JoAnne RockerE-prints and the Open Archives Initiative by Simeon WarnerLeveraging OAI harvesting to disseminate theses by Hussein Suleman; Edward A Fox
On the OLAC list there has been a discussion on the use of realtor terms. I wrote that they were valid in field 100 but could not imagine when they might be used there. I'm sure I've never seen it.Well, it seems there is someone who has a use for every field and subfield. I received a reply from a library that has oral histories. They use interviewee in 100 to bring out the fact it is an interview and it is not the person giving the interview. Those folks are in 700 with the realtor interviewer. Makes sense.

A new version of ZMARCO has been released.
The only change to this version is the use of the latest version of VB-ZOOM 1.2c1.1.2 for all of the Z39.50 and MARC functionality. This significantly improves the support for handling MARC records, especially issues surrounding character encodings.
The paper Quality Assurance for Digital Learning Object Repositories: How Should Metadata be Created? by Sarah Currier and Jane Barton is available, in MS Word format.
Metadata is a powerful component of any digital learning object repository, the key that unlocks its potential. Much work has already been done within the learning technology community to assure metadata quality, focused on the development of the metadata infrastructure, in the form of standards and specifications, and the implementation of this infrastructure within repositories. There has been an assumption that metadata creation will be straightforward, and that authors of learning materials will be the most appropriate metadata creators. However, repositories are beginning to report significant difficulties in obtaining good quality metadata from their contributors and it is increasingly apparent that the issue of metadata creation warrants attention. This paper surveys the growing body of evidence to scope the issue of metadata creation and to identify questions for further investigation.

A beta version of a Perl Open Archives Initiative-Protocol for Metadata Harvesting library has been uploaded to CPAN as Net::OAI::Harvester.
Net::OAI::Harvester is a Perl extension for easily querying OAI-PMH repositories. OAI-PMH is the Open Archives Initiative Protocol for Metadata Harvesting. OAI-PMH allows data repositories to share metadata about their digital assets. Net::OAI::Harvester is a OAI-PMH client, so it does for OAI-PMH what LWP::UserAgent does for HTTP.The guiding principle behind OAI-PMH is to allow metadata about online resources to be shared by data providers, so that the metadata can be harvested by interested parties. The protocol is essentially XML over HTTP (much like XMLRPC or SOAP). Net::OAI::Harvester does XML parsing for you (using XML::SAX internally), but you can get at the raw XML if you want to do your own XML processing, and you can drop in your own XML::SAX handler if you would like to do your own parsing of metadata elements.
There is a new Wiki devoted to Open Source, OSPedia. If you have something to say on the topic, just go and add some content. Wiki are Web pages that anyone can edit. This would be a good place for the library community to show the hackers what some of us have been doing.
Welcome to the OpenSourcePedia (or FreeSoftwarePedia). This is a collaborative resource built for and by a community of people interested in the advancement of collaborative software. Often referred to as "open source software" and/or "free software" both terms reflect the primary interest in working together in an spirit of openness, transparency, and community to produce superior software that you can share freely with others. The aim of the 'Pedia is to be an all encompassing resource for software users, developers, and the curious to find information about anything relating to our efforts in these endevours. We're just getting started so feel free to pitch in!
OCLC has a nice selection of tips for Dewey Classification. The publication is irregular, so it might be a good idea to use a page watcher to keep up to date. Maybe they could set it up so people could subscribe to receive the new ones by e-mail. Or they could provide an RSS feed.Some of the recent tips include:

BlojsomIT! is a servlet version of MoveableType's bookmarklet. We had a previous version but this one is much improved. Essentially it enables you to easily blog an interesting page using one click (well, OK two clicks). You can also send trackback pings. Take a look at the form and see if you'd like it (you have to be running blojsom). If you do, feel free to download it. Feedback welcome.So what's this got to do with the semantic web? Not much at the moment, but William is working hard on extending BlojsomIT! to a SemBlogIT! tool, which is starting to look really cool. Stay tuned.Seen at The Semantic Blogging Demonstrator.

Greenstone v2.40 has now been released.Some new features include:
- One of the trickier parts of using Greenstone is coming up with a configuration file for your collection. To help learn how to do it, here is a new document that presents, and explains, the configuration files for a few actual Greenstone collections, and also gives an example of how Greenstone's appearance can be customized.The complete Greenstone interface, and all documentation, is available in English, French, Spanish, Russian and Kazakh. Greenstone also has interfaces in many other languages.Recently, Japanese, Thai, Czech, and Galician interfaces have been added
