In this session, Dan Scott (the contributor of the schema.org microdata enhancement for Evergreen and a participant in the schemabibex effort to extend schema.org to better support bibliographic data) will discuss the origins of the microdata standards, explain how nominally machine-readable cataloguing data can fit into the machine-actionable semantic web, reflect on the impact that a microdata-enabled catalogue has had at Laurentian University to date, and offer some thoughts about the future of microdata – including the schema.org and RDFa Lite standards. / WARNING: you may come away with ideas not only for enriching your library system, but for your web site and other web-based library applications as well! Microdata enables search engines and other automated processes to make sense of the data on a web page — like identifying the title, author, and identification number of a book from all of the other content on a given page. Web pages enhanced with microdata contribute to the semantic web, and in turn are more likely to be incorporated into search engines and advanced web applications. If it sounds like we should publish microdata from Evergreen’s catalogue, you will be pleased to know that Evergreen was (naturally) the first library system to incorporate microdata in its default public catalogue with the 2.2.0 release in June 2012.

This dissertation focuses on the data exchange bibliographic formats that have been used in the libraries since the 1960s. There have not been many changes over the decades although librarians have been calling for them. Since the beginning of the new millennium, there has been a growing pressure for change. The aim of this dissertation is to try to summarize the activities in this field and to outline possible future development. The formats used in the past and in the present are analysed in the first part. It is possible to predict the future development on the basis of the analysis of individual projects and on the basis of surveys. The results of the analysis suggest that these activities are headed to a linked data publication model that preserves the current cataloguing procedures. Keywords: exchange formats, bibliographic data, MARC format, MARC 21 format, linked data, BIBFRAME, Schema.org, cataloguing

Esta tesis propone la aplicación de la experiencia de usuario accesible para el diseño de entornos web de recursos educativos abiertos accesibles. Los principales aportes de son: (i) la recopilación del estado de la cuestión mediante una revisión sistemática de la literatura; (ii) la caracterización de los problemas de accesibilidad, usabilidad y arquitectura de información en los entornos web de REA; (iii) la propuesta del concepto de experiencia de usuario accesible para guiar el desarrollo de entornos web de REA; (iv) la respuesta adaptativa del entorno web de REA en base a perfiles de discapacidad; (v) la evaluación de experiencia de usuario en un entorno web de prueba; (vi) el estudio de la viabilidad de aplicación de anotaciones semánticas con microdatos, para mejorar la información en los resultados de búsqueda de REA en la Web.
