This paper explores the relationship between the categories assigned to the Wikipedia articles with the description and metadata generated in Wikidata. It is proposed to use the categorization of Wikipedia articles to enrich the description of entities in Wikidata. For this, the literals of the categories could be processed using natural language processing techniques (NLP), establishing patterns that allow the identification of properties as well as entities or values with which to construct statements for an entity. The sequence of operations would be the following: 1) Selection of a coherent set of categories, 2) Establishment of patterns of processing of literals and assignment to properties and elements of Wikidata, 3) Creation of declarations with qualifiers for each category processed and 4) Programming of bots for the automatic processing of categories, enrichment and validation of Wikidata element descriptions. The technique shown in this paper focuses on the use of different properties and entities of Wikidata to develop point 3. The automation of a process to enrich and validate the declarations of each element, would allow to reuse existing edition dynamics. It would also help to elaborate a scheme of concepts of higher quality, by specifying the meaning of the categories that suppose a composition of several terms and that actually solve descriptive needs by other means.

This paper shows the description of the conceptual aspects of audiovisual content through the Audio-Visual Semantics ontology (AVS) that allows to represent actions, characteristics and interactions between entities and / or elements with a multilevel granularity. For this, it is considered that the audiovisual pieces are composed of sequences. In these sequences it is possible to identify different happenings that can be described. Happenings are composed of a series of elements such as agents, actions, targets or other events. The use of qualifiers (specifying their scope and value) is contemplated to define qualities or attributes of the different elements that intervene in an event. The agents, actions, objects and qualifiers are not defined extensively in the ontology itself, but are referenced as concepts of SKOS vocabularies, which avoids modifying the AVS ontology and allows to define semantic relations between concepts and multilingual labeling. Currently, the AVS ontology is in development and in the validation phase through the description of audiovisual pieces and the verification of the results obtained.

DBpedia y Wikidata are two semantic projects built on the top of Wikipedia encyclopedic content that has been crowdsourced, created, and maintained by thriving online communities. This article outlines differences and similarities between these two projects, pointing out their data models, curation patterns, and technologies. In addition, it forecasts some possible trends for their co-evolution as crossdomain open knowledge graphs and their significant value as hubs of interlinking datasets of various domains.

How current news impacts the creation of articles in the free online encyclopedia Wikipedia is studied. Unlike the traditional editorial model, Wikipedia articles on news events are produced at the same time as they happen, and, as a result, conflicts between journalism and encyclopedic criteria arise. The editorial policies and practices that the Wikipedia community of editors have been applying to the encyclopedic coverage of present facts, people, and breaking news are analyzed.

This article reflects on the concept of source code as it is applied to areas other than computer programming, and relates it to scientific communication, network activism, and micropolitical actions. The usefulness of learning the essential aspects of programming as a universal language and digitizing of objects, buildings, and historical sites in 3D, by digital libraries of cultural heritage, are discussed.

An understanding of information literacy programs should evolve to empower people and communities. These programmes would serve as training in those types of social technologies that enhance the capability of self-organization, social and democratic influence, alternative systems of consumption and services, and so on. Keeping in mind the social and technological attempts to face situations of scarcity caused by the present European economic crisis, the framework of this approach is in the main documents of the European Union concerning citizenship skills, as well as in social demands on open government (transparency, participation and collaboration). Based on the absence or inadequacy of the issues in the syllabi of most information literacy programmes, guidelines are suggested in order that they may be promoted by library systems and other public networks of socio­educational action, emphasizing learning for social innovation.

This report highlights the most important recent activity in the field of semantic web, analyzing the most innovative aspects of the new RDF 1.1 recommendation, and discussing the first public working draft of Data on the web best practices. The evolution of semantic markup is analyzed, both from the point of view of standards and the practical applications on the Web. Wikipedia is identified as a dynamic factor in the semantic web, especially through the DBpedia and WikiData initiatives. Europeana and the Digital Public Library of America are clear references in the description of networked digital resources.

Numerous social-oriented collaborative technologies, called social technologies, are presented within the framework of digital literacy. They have an impact in the empowerment and self-organization of individuals and groups as they set their own goals and increase their influence in public opinion. These digital platforms also help to obtain practical outcomes by new forms of interchange

The sharing of research data is a hot topic at the international level, especially due to the development of e-science, based on collaborative working methods that use technology in an intensive manner. The amount of digital data and of its sharing is growing fast, and a lack of proper management could limit the potential benefits to stakeholders (researchers, governments and public funding agencies, research managers and libraries, and finally the publishing sector). The aim of this review is first to place the sharing of electronic research data in the context of its appearance and of open environments; secondly, it describes the life cycle model of data preservation; finally, it describes several initiatives dealing with methodologies and technologies. In parallel, international developments and highlights needs that exist in Spain are described.

This work presents trends and models for electronic publishing of nonfiction books, with emphasis on education resources. The context of institutional publishers (universities, cultural centres) is outlined, from the point of view of global online publishing strategies that try to improve productivity by combining technologies and open licenses, innovations in format, and content repurposing and reuse.

The tensions between centralization and decentralization in complex enterprise web sites are addressed from the perspective of conventional information architecture, based on the “islands of information” metaphor used by Rosenfeld and Morville. The needs include the identification and shaping of information spaces, the ability to manage multiple autonomous websites consistently, and a deeper knowledge of enterprise information architecture methodologies.

Objetivo. Describir y evaluar el uso en Wikipedia de enlaces a las colecciones digitalizadas en bibliotecas, archivos y otras instituciones culturales. -- Metodología. El estudio se realiza sobre la totalidad de los artículos de las ediciones en español y catalán de Wikipedia, usando una herramienta de análisis de wikis. Se realiza una selección amplia de 81 colecciones digitales españolas de diferente alcance. También se toman datos de otros proyectos de digitalización para poder comparar los resultados. -- Resultados. Se muestra una presencia aún débil de enlaces desde Wikipedia, excepto para la Biblioteca Virtual Miguel de Cervantes, cuyas magnitudes son sensiblemente diferentes. Algunas colecciones especializadas son más usadas, pero en general se aprecia una falta de atención hacia estas colecciones desde el colectivo de editores de Wikipedia, lo cual debería tenerse en cuenta en el desarrollo de los proyectos de digitalización tipo Europeana.Objectives. To describe and evaluate the use of Wikipedia links to digitized collections held in libraries, archives and other cultural institutions. -- Methodology. The study examines all the articles included in the Spanish and Catalan versions of Wikipedia, using a wiki analysis tool. A broad selection of 81 Spanish digital collections of varying sizes is then made. Data are taken from other digitization projects for a comparison of results. -- Results. The use of links from Wikipedia remains relatively unexploited, with the exception of those to the Miguel de Cervantes Digital Library, where the scale of use is markedly greater. Some specialized collections are more frequently used, but in general there is a lack of attention paid to these collections by the team of Wikipedia editors. This needs to be taken into account in the development of digitization projects in line with the Europeana portal.

La Wikipedia va néixer al ciberespai. Els seus primers anys es van caracteritzar per una feina distribuïda i asíncrona entre usuaris de tot el planeta, que amb prou feines tenien relació personal fora de la xarxa. Amb el pas del temps, alguns dels seus voluntaris van fer les anomenades wikitrobades, però al començament les reunions de wikimedistes tenien la finalitat d'estrènyer llaços i no comportaven cap millora directa dels continguts dels projectes. Més endavant van sorgir iniciatives presencials en les quals es van involucrar, a més de voluntaris, algunes entitats culturals; la més recent i que ha tingut més impacte és Wiki Loves Monuments 2011, un concurs destinat a fotografiar monuments de divuit països europeus, entre els quals hi ha Espanya. Gràcies a l'alta participació, s'han pres en conjunt més de 160.000 fotografies de monuments. Espanya ha ocupat el tercer lloc en nombre d'imatges. En aquest article estudiem els orígens de Wiki Loves Monuments, com es va posar en marxa, com es va desenvolupar i els resultats obtinguts. L'èxit de l'edició 2011 i les peticions d'altres països han fet que ja es treballi en l'organització de Wiki Loves Monuments 2012, aquesta vegada a escala mundial., Wikipedia nació en el ciberespacio. Sus primeros años se caracterizaron por un trabajo distribuido y asíncrono entre usuarios de todo el globo, que apenas tenían relación personal fuera de la red. Con el paso del tiempo, algunos de sus voluntarios realizaron los llamados wikiencuentros, pero en un inicio las reuniones de wikimedistas tenían la finalidad de estrechar lazos y no suponían una mejora directa de los contenidos de los proyectos. Con posterioridad surgieron iniciativas presenciales en las que se involucraron, además de voluntarios, algunas entidades culturales; la más reciente y con un mayor impacto es Wiki Loves Monuments 2011, un concurso destinado a fotografiar monumentos de dieciocho países europeos, entre ellos España. Gracias a la alta participación, se han tomado en conjunto más de 160.000 fotografías de monumentos. España ha ocupado el tercer puesto en número de imágenes. En este artículo estudiamos los orígenes de Wiki Loves Monuments, su puesta en marcha, su desarrollo y sus resultados. El éxito de la edición 2011 y las peticiones de otros países han llevado a que ya se esté trabajando en la organización de Wiki Loves Monuments 2012, esta vez a escala mundial., Wikipedia came into being in cyberspace. Its early years were marked by asynchronous work by users located all over the world who hardly ever related on a personal level outside the network. With time, some of the volunteers met at what were called Meetups, encounters initially aimed at tightening bonds and not at bringing about any direct improvement in project content. Face-to-face initiatives later took place that involved not just volunteers but also cultural entities. The most recent event and the one with the greatest impact was Wiki Loves Monuments 2011, a competition to photograph monuments in 18 European countries, including Spain. The high level of participation led to 160,000 photographs of monuments being taken, with Spain occupying the third place in terms of number of photographs. In this paper we explore the origins, implementation, development and results of Wiki Loves Monuments. The success of the 2011 edition and requests from other countries has led to organization of Wiki Loves Monuments 2012, which will be held at the global level.

The importance for libraries, archives and cultural heritage institutions of open innovation on the basis of linked open data basis is discussed. As the web evolves into a global data space, libraries should provide their datasets using RDF technologies and open licenses to strengthen innovative services developed by third parties reusing their metadata and digital contents.

This paper justifies participation by public libraries in designing and publishing in “localpedias” as a way to promote collaboration in the creation of local content. For this purpose, the “localpedia” concept is explained and some of the main Spanish localpedia experiences described. Finally, some difficulties in consolidating this way of creating and sharing local knowledge are discussed.

This book combines different points of view about cultural digital contents public policies, that often take divergent paths. Various experiences on integrated dissemination are presented: based on cultural heritage digital preservation projects (Memoria de Madrid); collaborative content creation (CTpedia); multimedia production (Canal Historia del Portal Región de Murcia Digital); and an open access digital library and harvester (Biblioteca Digital de la Región de Murcia). A conceptual framework for local digital content initiatives and strategies is also exposed.

Reflection on the role of cultural institutions, such as public libraries, archives and musesums, in the digital collaborative information projects aimed to local content.

Reflection on the role of public libraries in the digital information environment. The appropriate digital content niche that concerns libraries working in a collaborative approach with other cultural and local institutions is defined. The need for community-oriented content and crowdsourcing is described. Libraries could act as mediators between local cultural agents to support information quality and licensing in social web sites.

Having observed the progress of museums in the computerization of collections, the author warns about the need to ensure that the cataloguing efforts adopt appropriate technological solutions to produce value on Web 2.0. Metadata should be able to define complex cultural objects much more broadly than the simple description of a single piece or monument. Context and environment information should be added. Formal description processes should not be limited to inside the museum.

This paper presents the characteristics and functionalities of the Wikimedia Commons image databank shared by all Wikipedia projects. The process of finding images and ilustrating Wikipedia articles is also explained, along with how to add images to the bank. The role of cultural institutions in promoting free and open cultural heritage content is highlighted.
