Using open source software tools, the ResCarta Foundation has
developed a means to store, retrieve, and display digital
collections that does not utilize proprietary file formats or
viewing systems.

Rather, this system uses industry standard TIFF files with
metadata contained in METS/MODS files along with a search
engine to provide a friendly means to integrate a complete
digital collection.

Our presentation will demonstrate this open source software
suite as well as the ResCarta Standards.

I'd like a chance to talk about SRW/U. I can extend it to talk about
OpenSearch and MXG as well. We've got open source code to share and
experience with using that code in a cluster environment to search large
databases.

I can talk about any or all of that.

Thanks!

Connecting Everything with unAPI and OPA

unAPI is a simple-to-use, simple-to-implement API for web sites that allows rich object access and can be easily layered over existing services like Atom, OpenSearch, OAI-PMH, or SRU. OPA is a general-purpose identifier resolver that wraps API calls to heavily-used but incompatible web services like those from Amazon, Flickr, and Pubmed.

Together they will do the same thing we do every code4libcon - try to take over the world!

AHAH: When Good is Better than Best
~~~~~~~~~~~~~~~~~~~~~~~
It can be difficult to enhance, fix or extend legacy/closed-source web applications such as online catalogs without being able to alter the web application directly.

I will discuss using AHAH (Asynchronous HTTPRequest and HTML) as a technique for doing so and compare it to AJAX, proxying and SSI. Examples from the Seattle Public Library's next generation online catalog will be presented. Performance and scalability concerns will also be covered, time permitting.

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Building an International Network of Shared Metadata
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Libraries tend to avoid collecting any sort of long-term data about patron library usage or preferences wherever possible. Although this is done to protect patron privacy, it also greatly restricts the range of social features (such as suggestions based upon a patron's checkout history or patron-supplied reviews and comments) that library catalogs can offer.

I will discuss cryptographic techniques for securely and anonymously collecting and sharing user-supplied metadata across library systems.

The Purdue University Libraries has developed an interface, OAISRB, for the Open
Archives Initiative Protocol for Metadata Harvesting (OAI-PMH) to data grid resources
served by the Storage Resource Broker (SRB). OAI-PMH defines a protocol for
exposing and harvesting metadata from networked repositories. Developed by the San
Diego Supercomputer Center, SRB provides a uniform interface to heterogeneous storage
over a network. This presentation will briefly introduce both technologies and
demonstrate their int

What Blog Applications Can Teach Us About Library Software Architecture

Casey Bisson

The number of programmers in the library world is growing and our individual efforts have shown great promise, but they exist largely as a spectacle that few libraries can enjoy. We need better means to aggregate our efforts and share solutions that can be employed by libraries without programming staff.

Looking outside libraries, we see some interesting examples in the blog world. The blog world is growing with new bloggers every day, but the most interesting aspect is how many people with limited technical skills are using (maintaining and configuring) blog applications like WordPress or Moveable Type, and how quickly the contributions of the many plugin and theme developers are implemented on those blogs. What lessons can we learn from this and how might a library application built from those lessons work? Are some software architectures better at leveraging the network effects of the growing number of developers in our community than others?

Quality Metrics

Aaron Krowne

This talk will discuss the core development activities of the “Quality
Metrics” project at Emory’s Woodruff Library. This project is being
conducted under an IMLS grant to research requirements for and build
a working prototype digital library search system.

What this project is doing that is new is truly generalizing and
integrating explicit and latent quality indicators which allow
users to ascertain the fitness of digital library resources. Most
search engine components have only one indicator: content-query
