The latest issue of the Code{4}lib Journal has some articles of interest.

HTML5 Microdata and Schema.org
Jason Ronallo

On June 2, 2011, Bing, Google, and Yahoo! announced the joint effort Schema.org. When the big search engines talk, Web site authors listen. This article is an introduction to Microdata and Schema.org. The first section describes what HTML5, Microdata and Schema.org are, and the problems they have been designed to solve. With this foundation in place section 2 provides a practical tutorial of how to use Microdata and Schema.org using a real life example from the cultural heritage sector. Along the way some tools for implementers will also be introduced. Issues with applying these technologies to cultural heritage materials will crop up along with opportunities to improve the situation.

Using VuFind, XAMPP, and Flash Drives to Build an Offline Library Catalog for Use in a Liberal Arts in Prison Program
Julia Bauder

When Grinnell College expanded its Liberal Arts in Prison Program to include the First Year of College Program in the Newton Correctional Facility, the Grinnell College Libraries needed to find a way to support the research needs of inmates who had no access to the Internet. The library used VuFind running on XAMPP installed on flash drives to provide access to the Libraries? catalog. Once the student identified a book, it would be delivered from the Libraries to students on request. This article describes the process of getting VuFind operating in an environment with no Internet access and limited control of the computing environment.

Improving the presentation of library data using FRBR and Linked data
Anne-Lena Westrum, Asgeir Rekkavik, Kim Tallerås

When a library end-user searches the online catalogue for works by a particular author, he will typically get a long list that contains different translations and editions of all the books by that author, sorted by title or date of issue. As an attempt to make some order in this chaos, the Pode project has applied a method of automated FRBRizing based on the information contained in MARC records. The project has also experimented with RDF representation to demonstrate how an author?s complete production can be presented as a short and lucid list of unique works, which can easily be browsed by their different expressions and manifestations. Furthermore, by linking instances in the dataset to matching or corresponding instances in external sets, the presentation has been enriched with additional information about authors and works.

Presenting results as dynamically generated co-authorship subgraphs in semantic digital library collections
James Powell, Tamara M. McMahon, Ketan Mane, Laniece Miller, Linn Collins

Semantic web representations of data are by definition graphs, and these graphs can be explored using concepts from graph theory. This paper demonstrates how semantically mapped bibliographic metadata, combined with a lightweight software architecture and Web-based graph visualization tools, can be used to generate dynamic authorship graphs in response to typical user queries, as an alternative to more common text-based results presentations. It also shows how centrality measures and path analysis techniques from social network analysis can be used to enhance the visualization of query results. The resulting graphs require modestly more cognitive engagement from the user but offer insights not available from text.

On Dentographs, A New Method of Visualizing Library Collections
William Denton

A dentograph is a visualization of a library?s collection built on the idea that a classification scheme is a mathematical function mapping one set of things (books or the universe of knowledge) onto another (a set of numbers and letters). Dentographs can visualize aspects of just one collection or can be used to compare two or more collections. This article describes how to build them, with examples and code using Ruby and R, and discusses some problems and future directions.
