liveTopics is a tool that enhances the Radio Userland knowledge-logging application making it an ideal personal knowledge sharing platform. In it’s initial release liveTopics provides the ability to attach meta data or topics to each post to your weblog. These are used to generate a Table of Contents to make semantic browsing and cross-referencing possible. The next release will include functionality for sharing topic information across a number of weblogs using the XTM format. This will support the creation of corporate weblog directories. Future integration’s include providing topic information in outgoing RSS feeds to allow clever aggregation.I'm not using Radio Userland for this 'blog so there is no way I can check it out. I hope they are using standards like Dublin Core and RSS 1.X. The choice of terms to describe something can also be important and hinder access. I use Texas, Tex. TX, n-us-tx, 4030, 77058-1113 at any time to describe about the same place. My choice depends on the setting and is not usable in other contexts. The folks at Blogchalking are finding out the problems in dealing with just U.S. states. Still this is the beginning of a system of access. Interesting.

This work presents a method for the adjustment of index weights by processing text that has been highlighted by users. Text in a document is highlighted using an application which provides annotation facilities in order to support active reading. Highlighted text is supposed to be of special relevance and the method tries to improve the index weights of terms located in these highlighted fragments.
Over the past year, the Boston College libraries have been engaged in making available to our users two new resources, MetaLib and SFX. MetaLib is portal/gateway software that allows for simultaneous searching of several databases, as well as some options to customize the interface. SFX technology provides context-sensitive reference linking from citations to extended services. In this article we review the pedagogical, technical, and service reasons for making these resources available. We discuss how we believe these technologies respond to current student use of the library, and how we approached the installation process. We also review the challenges of the installation (both technical and service) and future possibilities.
The issue also has articles on Dublin Core, CatExpress, scanning catalog cards, and cataloging and processing of three-dimensional artifacts.

Today, powerful data grid technologies such as the Storage Resource Broker (SRB), developed at the San Diego Supercomputer Center (SDSC) for scientific computing, are showing promise of being able to preserve these digital holdings. SDSC and Library of Congress are collaborating to evaluate the SRB data grid software for preservation and management of priceless national digital collections - part of the nation's heritage - for decades and centuries into the future.

Blog owners will be able to view the list of their subscribers. On the flip side, if subscribers want their email address hidden from view, they can set their account to "private" in their Profile section. In fact, this option is in place now, if you want to use it.You can rest assured I'll not pass your addresses on to any third party or send you spam. I'm curious as to who is a subscriber, so I will take a look some time. This applies to any 'blog you have subscribed to using Bloglet.
In the faddish dot-com world it's tempting to dismiss metadata as this nanosecond's buzzer button, but metadata is really an age-old answer to an age-old problem. The problem is, how to get the most out of a stored collection of information. Datastores are bigger than ever and so is the problem. A consensus is growing that metadata is the answer. Metadata is often described as "information about information" but I prefer to think of it as another layer of information - simplified, distilled, made orderly - created to help people use an information source.Thanks to Matthew at Library Techlog for this item.

The guiding principle behind the initiative is that by creating standards in the weblog metadata "problem space", we can enable greater collaboration and interaction between existing applications, as well as paving the way for future, currently unforeseen metadata applications by reducing or eliminating much of the redundant, "reinventing the wheel" work currently involved in creating a new weblog metadata application.
I hope, with compatible systems may come standards, structure in XML and the ability to archive and search the archives of messages. Another benefit will be for libraries that are using IM for online reference.
Thanks to Jenny at the Shifted Librarian. Welcome back, I've missed your insights.

OCLC is investigating how best to implement IFLA's Functional Requirements for Bibliographic Records (FRBR). As part of that work, we have undertaken a series of experiments with algorithms to group existing bibliographic records into works and expressions. Working with both subsets of records and the whole WorldCat database, the algorithm we developed achieved reasonable success identifying all manifestations of a work.
The Registry includes:
- Full-text search support
- The ability to navigate the DC vocabulary using a number of pre-defined queries.
- Internationalization support that includes term and user interfacetranslations in 23 different languages (thanks to the efforts of over 40volunteers)
- Two user interfaces, intended to support both metadata specialists and RDF experts
The Metadata Registry is the primary focus of the DCMI Registry Working Group. We encourage your feedback on this release and remind working group members that we will be discussing Phase 2 functional requirements at the DC2002 meeting in Florence in October. Prior to that meeting we will post agenda and discussion items on this list. Please direct your comments and suggestions to: mailto:DC-REGISTRY@JISCMAIL.AC.UK
