Cooperation between libraries is a universal language spoken in different dialects. In 1996 the libraries of the state-funded universities and the National Library of Catalonia (Spain) formed the Consortium of Academic Libraries of Catalonia (CBUC) to act as a channel for cooperation. The organization and activities of CBUC are an example of how this universal language has been adapted to the specific characteristics of the Libraries of Catalonia. Catalonia is an autonomous region of Spain with 7 million inhabitants with its own language, history and traditions and with a strong feeling of own identity that facilitates the cooperation. Thanks to this (and also to the hard work of the member libraries), since then, CBUC has created a union catalogue, an interlibrary lending program, the Digital Library of Catalonia, a cooperative store, different cooperatives repositories and other cooperation programs. One of these cooperatives repositories is RACO (Catalan Journals in Open Access, www.raco.cat) where can be consulted, in open access, the full-text articles of scientific, cultural and scholar Catalan journals. The main purpose of RACO is to increase the visibility and searches of the journals included and to spread the scientific and academic production published in Catalonia. This purpose makes specific in three aims: encourage the electronic edition of Catalan journals; be the interface that allows the whole search of all the journals and provide the instruments for its preservation. There are currently 244 journals in RACO, that includes more than 85.000 articles (80% in OA) from 50 publishing institutions. Since it got into operation it has had more than 4 millions of queries. These 244 journals offer the full-text of all the published issues. Nevertheless, some journal can have a delay between the introduction of the table of contents and the full-text for the recent issues. From 2005 we have a plan of retrospective digitization that has allowed to digitize more than 350.000 pages of back issues. The RACO repository works with the open source program OJS (Open Journal Systems, http://pkp.sfu.ca/ojs/) and uses Dublin Core Metadata and the interoperability protocol created by Open Archives Initiative (OAI) which allows to increase the visibility of the articles published in journals offering oneself together with other international repositories.

The HUPO Proteomics Standards Initiative has developed several standardized data formats to facilitate data sharing in mass spectrometry (MS)-based proteomics. These allow researchers to report their complete results in a unified way. However, at present, there is no format to describe the final qualitative and quantitative results for proteomics and metabolomics experiments in a simple tabular format. Many downstream analysis use cases are only concerned with the final results of an experiment and require an easily accessible format, compatible with tools such as Microsoft Excel or R. We developed the mzTab file format for MS-based proteomics and metabolomics results to meet this need. mzTab is intended as a lightweight supplement to the existing standard XML-based file formats (mzML, mzIdentML, mzQuantML), providing a comprehensive summary, similar in concept to the supplemental material of a scientific publication. mzTab files can contain protein, peptide, and small molecule identifications together with experimental metadata and basic quantitative information. The format is not intended to store the complete experimental evidence but provides mechanisms to report results at different levels of detail. These range from a simple summary of the final results to a representation of the results including the experimental design. This format is ideally suited to make MS-based proteomics and metabolomics results available to a wider biological community outside the field of MS. Several software tools for proteomics and metabolomics have already adapted the format as an output format. The comprehensive mzTab specification document and extensive additional documentation can be found online.

En aquest treball es fa una breu introducció a la web semàntica i el seu estat actual. S'analitzen els llenguatges que hi ha a la base del munt de recomanacions del World Wide Web Consortium (XML, XML Schema, RDF i RDF Schema) i s'examinen diferents sistemes de gestió de bases de dades que donen suport a les metadades, que són la base de la web semàntica.

En aquest treball es realitza una descripció dels llenguatges que constitueixen la base de la construcció de la Web Semàntica: l'XML, l'RDF i l'OWL. En concret, es realitza un estudi de la base de dades lèxica WordNet. Finalment, es presenta el disseny i la implementació d'una ontologia per representar les relacions lèxiques dels mots del català. A partir d'aquesta ontologia es crea una petita base de dades basada en la temàtica dels animals de companyia. Aquest cas pràctic permet extreure conclusions sobre els avantatges d'introduir metadades en els documents electrònics, i sobre les facilitats que ofereixen les aplicacions actuals pel desenvolupament d'aquest tipus de documents.

Aquest projecte avalua diferents BD:XML natives per a desar i recuperar documents XML basats en l'estàndard MPEG-7. Es tracta d'un estàndard que proposa un llenguatge per descriure el contingut (metadades) de documents multimèdia, és a dir, àudio i vídeo. El seu format de representació és XML i es basa en un esquema ja predefinit (XMLSchema d'MPEG-7).

Actualmente se pretende que los ordenadores puedan entender la semántica de la información que hay en la Web y que sea posible integrar diversas fuentes de información independientemente de la procedencia y formato de éstas, haciendo así una Web Semántica. Uno de los mayores problemas que tiene la Web Semántica es la falta de contenidos semánticos, principalmente debido a la falta de métodos de anotación automáticos existentes. Una forma de resolver este problema se basa en esconder tras aplicaciones que la gente usa diariamente, como los juegos on-line, estos procesos de generación de metadatos semánticos. El objetivo de este proyecto es estudiar diferentes iniciativas que tratan de enmascarar la generación de metadatos semánticos a través de los juegos on-line y el desarrollo de un prototipo de casual game para anotar semánticamente recursos. Se trata de un juego sencillo de pregunta-respuesta, donde dos usuarios concurrentes contestan a preguntas preestablecidas y definidas dentro de una ontología de dominio, obteniendo puntos en aquellas preguntas donde hayan dado la misma respuesta.

Over the past year, the Open University of Catalonia library has been designing its new website with this question in mind. Our main concern has been how to integrate the library in the student day to day study routine to not to be only a satellite tool. We present the design of the website that, in a virtual library like ours, it is not only a website but the whole library itself. The central point of the web is my library, a space that associates the library resources with the student's curriculum and their course subjects. There the students can save the resources as favourites, comment or share them. They have also access to all the services the library offers them. The resources are imported from multiple tools such as Millennium, SFX, Metalib and Dspace to the Drupal CMS. Then the resources' metadata can be enriched with other contextual information from other sources, for example the course subjects. And finally they can be exported in standard, open data formats making them available for linked data applications.

The Andalusian Public Health System (Sistema Sanitario Público de Andalucía -SSPA) Repository is the open environment where all the scientific output generated by the SSPA professionals, resulting from their medical care, research and administrative activities, is comprehensively collected and managed. This repository possesses special features which determined its development: the SSPA organization and its purpose as a health institution, the specific sets of documents that it generates and the stakeholders involved in it. The repository uses DSpace 1.6.2, to which several changes were implemented in order to achieve the SSPA initial goals and requirements. The main changes were: the addition of specific qualifiers to the Metadata Dublin Core scheme, the modification of the submission form, the integration of the MeSH Thesaurus as controlled vocabulary and the optimization of the advanced search tool. Another key point during the setting up of the repository was the initial batch ingest of the documents.

BACKGROUND. Bioinformatics is commonly featured as a well assorted list of available web resources. Although diversity of services is positive in general, the proliferation of tools, their dispersion and heterogeneity complicate the integrated exploitation of such data processing capacity. RESULTS. To facilitate the construction of software clients and make integrated use of this variety of tools, we present a modular programmatic application interface (MAPI) that provides the necessary functionality for uniform representation of Web Services metadata descriptors including their management and invocation protocols of the services which they represent. This document describes the main functionality of the framework and how it can be used to facilitate the deployment of new software under a unified structure of bioinformatics Web Services. A notable feature of MAPI is the modular organization of the functionality into different modules associated with specific tasks. This means that only the modules needed for the client have to be installed, and that the module functionality can be extended without the need for re-writing the software client. CONCLUSIONS. The potential utility and versatility of the software library has been demonstrated by the implementation of several currently available clients that cover different aspects of integrated data processing, ranging from service discovery to service invocation with advanced features such as workflows composition and asynchronous services calls to multiple types of Web Services including those registered in repositories (e.g. GRID-based, SOAP, BioMOBY, R-bioconductor, and others).
