Video Tour of OPAC Discovery Layer Tools

In March, I gave a presentation at the NISO forum on Next Generation Discovery Tools: New Tools, Aging Standards. For those that were there, you may remember the bulk of the presentation was in the screencast tours of the functionality of 10 OPAC enhancement tools. Topping out at over 750MB, the presentation file was too big to share, but I promised to put together a combination of the presentation audio and the screencast videos in a much more manageable size. That video, along with a cleaned up version of the audio, is posted below.

On Innovation in the ILS Marketplace

Last month the ILS Discovery Interface Task Force of the DLF called a meeting of library system vendors (including one commercial support organization for open source ILS software) to talk about the state of computer-to-computer interfaces in-to and out-of the ILS. The meeting comes as the work of the task force is winding down. An outcome of the meeting, the “Berkeley Accord,” was posted last week to Peter Brantley’s blog. The accord has three basic parts: automated interfaces for offloading records from the ILS, a mechanism for determining the availability of an item, and a scheme for creating persistent links to records.

Below are the supplemental links for the presentation at the NISO workshop on discovery layers in Chapel Hill, NC, on March 28, 2008.

Update 20080404T1124 : Carolyn McCallum at Wake Forest University posted a great summary of day two of the NISO discovery layer forum, including an overview of my talk. Thanks, Carolyn!

Foundational Pieces

The presentation started as an extension of a DLTJ blog post. I also mentioned Marshal Breeding’s Library Technology Report published in July/August of 2007 and available from the ALA store.

Services in a Service Oriented Architecture

This post is the second in a series about the application of the Service Oriented Architecture (SOA) system design pattern to library services. The first post in this series focused on defining “Service Oriented Architecture” using the analogy of a transportation network. This post goes into some detail about what makes a “service” in this architecture and offers an example using a hypothetical use case: a union library catalog (Open WorldCat) making a statement about the availability of a book.
