"Two Paths to Interoperable Metadataâ€  proposed a model for metadata
translation that offers substantial gains over models based on the
current community standard, which usually involves an XSLT
implementation. In this presentation, I will discuss implementation
issues with the Semantic Equivalence Expression Language (Seel), our
alternative to XSLT . I will show how Seel eases the complex task of
change management because it represents a more faithful computational
model of the metadata translation problem.

Digital libraries are supposed to foster reuse of digital content but it is hard to combine content from different sources. We are building prototype software that (1) converts different types of courseware to an XML interchange format based on OpenDocument and other specs/standards (2) enables the content to be disaggregated, recombined, re-styled and endowed with SCORM reporting behaviors and (3) realizes instructional design through the use of the SCORM (or IMS) Simple Sequencing. Will demo, discuss and am happy to talk about the bigger picture of reusability in educational digital libraries and standards if given a longer slot.

The aDORe Archive is a write-once/read-many storage approach for Digital Objects and their constituent datastreams. First, XML-based representations of multiple Digital Objects are concatenated into a single, valid XML file named an XMLtape. Second, ARC files, as introduced by the Internet Archive, are used to contain the constituent datastreams of the Digital Objects. The software was developed by the LANL Digital Library Research & Prototyping Team and is available under GNU LGPL license.

This talk will discuss the core development activities of the â€œQuality
Metricsâ€ project at Emoryâ€™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
similarity (â€œrelevanceâ€). Google only has two, adding PageRank to the
latter. Our system, QM-search, will have an unlimited number of these,
which will be customizable by the digital librarian for the target
community and collections, and even customizeable from user to user or
search to search.
Some basic examples of quality indicators that digital libraries might
be able to exploit would be activations (views online or check-outs in
circulation), selection (compilation in â€œbookmarkâ€ lists online or
additions to course reserves lists), extent of review (from a peer-
reviewed journal, conference, or not?), or citation-based metrics.
The ouput of QM-search will be in a completely generalized XML format,
with the search results represented as a structure based on the
structure specified in the input â€œorganization specâ€. This XML output
can be transformed into presentation HTML resembling anything from a
â€œlinearâ€ Google-like search results list to an A9-like column display to
more exotic groupings and breakdowns.
Requirements for QM-search are being gleaned from focus groups being
conducted at Emory (preliminary results will be shared), and development
is being conducted as a high-level layer atop the excellent Lucene open
source search engine project.

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 â€“ try to take over the world!
[Update 2006-02-28: Slides are here, in pdf.]
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?
Iâ€™m working on a project that attempts to answer those questions and I hope to release a public beta shortly (update: it's WPopac, online now). Iâ€™d like to demo it and ask for participation.
Update: slides posted.

If you have a blog please consider adding a playing card to your site:
You can use the following HTML:
Feel free to use the images directly from code4lib.org if you don't want to go through the effort of grabbing them. This will allow us to secretly discover your site by trawling our logs.
Having the playing card can let people know about code4lib.org who don't know about it already. For examples of how to use them check out roy or dchud.
