Purpose This paper reports on the first 20 years of the Open Language Archives Community (OLAC), comprehensive infrastructure for indexing and discovering language resources. Design/methodology/approach We begin with the original vision, assess progress relative to the original requirements, and identify ongoing challenges. Findings Based on the overview of OLAC history and recent developments and on the analysis of the situation in the language archives area as a whole, the authors propose an agenda for a more sustainable future for open language archiving. Originality/value This paper examines the progress of OLAC and discusses improvements in such areas as participation, access, and sustainability.

The authors examined the Wade Hall Consolidation Project at the University of Alabama Libraries Special Collections. The project involved the physical consolidation of more than 1,400 small, discrete collections donated by Wade Hall into larger, subject-based collections along with the merger of 287 existing digital collections to mirror the physical arrangement. This project’s goal was to improve access to and discovery of these collections by researchers. During physical consolidation, the archivists created subject-based collections with new finding aids and addressed issues including unclear provenance, legacy descriptions, inaccurate metadata, varying levels of processing, and lack of alignment with current archival best practices and standards. Digital consolidation of existing digital collections coincided with the migration to a new digital asset management system and presented its own challenges, including legacy descriptions, metadata transformation, digital preservation, and dealing with existing metadata shared on the Digital Public Library of America (DPLA) and other multi-institutional digital content aggregators. The authors sought to fill the gap in the literature concerning the consolidation of physical and digital collections and to provide guidance to others considering a consolidation project.

From A to investigates the relationship between media and culture by articulating questions regarding the role of markup. How do the codes of HTML, CSS, PHP, and other markup languages affect the Web's everyday uses? How do these languages shape the Web's communicative functions? This novel inquiry positions markup as the basis of our cultural, rhetorical, and communicative understanding of the Web.

This work demonstrates a low-cost, miniature data repository proof-of-concept. Such a system needs to be resilient to power and network failures, and expose adequate processing power for persistent, long-term storage. Additional services are required for interoperable data sharing and visualization. We designed and implemented a software tool called Airchive to run on a Raspberry Pi, in order to assemble a data repository for archiving and openly sharing timeseries data. Airchive employs a relational database for storing data and implements two standards for sharing data (namely the Sensor Observation Service by the Open Geospatial Consortium and the Protocol for Metadata Harvesting by the Open Archives Initiative). The system is demonstrated in a realistic indoor air pollution data acquisition scenario in a four-month experiment evaluating its autonomy and robustness under power and network disruptions. A stress test was also conducted to evaluate its performance against concurrent client requests.

Paper highlights the current state of open access repositories (OARs) movement in Agricultural field of Asian countries. It describes their characteristics in terms of types, contents, disciplines, languages covered, technical and operational issues, and policy matters. Compares and evaluates repositories against selected parameters and makes some recommendations for the growth of agricultural repositories Worldwide. Also presents a unified interface that can harvest metadata from different OAI-PMH compliant agricultural repositories Worldwide.

Purpose – This paper aims to introduce a transformation engine which can be used to convert an existing institutional repository installation into a Linked Open Data repository. Design/methodology/approach – The authors describe how the data that exist in a DSpace repository can be semantically annotated to serve as a Semantic Web (meta)data repository. Findings – The authors present a non-intrusive, standards-compliant approach that can run alongside with current practices, while incorporating state-of-the art methodologies. Originality/value – Also, they propose a set of mappings between domain vocabularies that can be (re)used towards this goal, thus offering an approach that covers both the technical and semantic aspects of the procedure.

In Web 2.0 users not only make heavy use of Col-laborative Information Services in order to create, publish and share digital information resources - what is more, they index and represent these re-sources via own keywords, so-called tags. The sum of this user-generated metadata of a Collaborative Information Service is also called Folksonomy. In contrast to professionally created and highly struc-tured metadata, e.g. subject headings, thesauri, clas-sification systems or ontologies, which are applied in libraries, corporate information architectures or commercial databases and which were developed according to defined standards, tags can be freely chosen by users and attached to any information resource. As one type of metadata Folksonomies provide access to information resources and serve users as retrieval tool in order to retrieve own re-sources as well as to find data of other users. The book delivers insights into typical applications of Folksonomies, especially within Collaborative Information Services, and discusses the strengths and weaknesses of Folksonomies as tools of knowl-edge representation and information retrieval. More-over, it aims at providing conceptual considerations for solving problems of Folksonomies and presents how established methods of knowledge representa-tion and models of information retrieval can successfully be transferred to them.

This short paper outlines the key components of the NERC DataGrid: a discovery service, a vocabulary service and a software stack deployed both centrally to provide a data discovery portal, and at data providers to provide local portals and data and metadata services.

The authors, who jointly serve as the Open Archives Initiative (OAI) executive, reflect on the three-year history of the OAI. Three years of technical work recently culminated in the release of a stable production version 2 of the OAI Protocol for Metadata Harvesting (OAI-PMH). This technical product, the work that led up to it, and the process that made it possible have attracted some favor from the digital library and information community. The paper explores a number of factors in the history of the OAI that the authors believe have contributed to this positive response. The factors include focus on a defined problem statement, an operational model in which strong leadership is balanced with solicited participation, a healthy dose of community building and support, and sensible technical decisions.
