Metadata quality issues in learning repositories
Metadata lies at the heart of every digital repository project in the sense that it defines and drives the description of digital content stored in the repositories. Metadata allows content to be successfully stored, managed and retrieved but also preserved in the long-term. Despite the enormous importance of metadata in digital repositories, one that is widely recognized, studies indicate that what is defined as metadata quality, is relatively low in most cases of digital repositories. Metadata quality is loosely defined as "fitness for purpose" meaning that low quality of metadata means that metadata cannot fulfill its purpose which is to allow for the successful storage, management and retrieval of resources. In practice, low metadata quality leads to ineffective searches for content, ones that recall the wrong resources or even worse, no resources which makes them invisible to the intended user, that is the "client" of each digital repository. The present dissertation approaches this problem by proposing a comprehensive metadata quality assurance method, namely the Metadata Quality Assurance Certification Process (MQACP). The basic idea of this dissertation is to propose a set of methods that can be deployed throughout the lifecycle of a repository to ensure that metadata generated from content providers are of high quality. These methods have to be straightforward, simple to apply with measurable results. They also have to be adaptable with minimum effort so that they can be used in different contexts easily. This set of methods was described analytically, taking into account the actors needed to apply them, describing the tools needed and defining the anticipated outcomes. In order to test our proposal, we applied it on a Learning Federation of repositories, from day 1 of its existence until it reached its maturity and regular operation. We supported the metadata creation process throughout the different phases of the repositories involved by setting up specific experiments using the methods and tools of the MQACP. Throughout each phase, we measured the resulting metadata quality to certify that the anticipated improvement in metadata quality actually took place. Lastly, through these different phases, the cost of the MQACP application was measured to provide a comparison basis for future applications. Based on the success of this first application, we decided to validate the MQACP approach by applying it on another two cases of a Cultural and a Research Federation of repositories. This would allow us to prove the transferability of the approach to other cases the present some similarities with the initial one but mainly significant differences. The results showed that the MQACP was successfully adapted to the new contexts, with minimum adaptations needed, with similar results produced and also with comparable costs. In addition, looking closer at the common experiments carried out in each phase of each use case, we were able to identify interesting patterns in the behavior of content providers that can be further researched. The dissertation is completed with a set of future research directions that came out of the cases examined. These research directions can be explored in order to support the next version of the MQACP in terms of the methods deployed, the tools used to assess metadata quality as well as the cost analysis of the MQACP methods

Developing a national item bank
The COLA project has been developing a large bank of assessment items for units across the Scottish further education curriculum since May 2003. These will be made available to learners mainly via colleges’ virtual learning environments. Many people have been involved in the development of the COLA item bank. Processes have included deciding on appropriate item types and subject areas, training authors, peer-reviewing and quality assuring the items and assessments, and ensuring they are interoperable and tagged with appropriate metadata

Metadata, or data about data, play a crucial rule in social sciences to ensure that high quality documentation and community knowledge are properly captured and surround the data across its entire life cycle, from the early stages of production to secondary analysis by researchers or use by policy makers and other key stakeholders. The paper provides an overview of the social sciences metadata landscape, best practices and related information technologies. It particularly focuses on two specifications - the Data Documentation Initiative (DDI) and the Statistical Data and Metadata Exchange Standard (SDMX) - seen as central to a global metadata management framework for social data and official statistics. It also highlights current directions, outlines typical integration challenges, and provides a set of high level recommendations for producers, archives, researchers and sponsors in order to foster the adoption of metadata standards and best practices in the years to come.social sciences, metadata, data, statistics, documentation, data quality, XML, DDI, SDMX, archive, preservation, production, access, dissemination, analysis
Proceedings of the 15th Conference on Knowledge Organization WissOrg'17 of theGerman Chapter of the International Society for Knowledge Organization (ISKO),30th November - 1st December 2017, Freie Universität Berlin
Wissensorganisation is the name of a series of biennial conferences /
workshops with a long tradition, organized by the German chapter of the
International Society of Knowledge Organization (ISKO). The 15th conference in
this series, held at Freie Universität Berlin, focused on knowledge
organization for the digital humanities. Structuring, and interacting with,
large data collections has become a major issue in the digital humanities. In
these proceedings, various aspects of knowledge organization in the digital
humanities are discussed, and the authors of the papers show how projects in
the digital humanities deal with knowledge organization.Wissensorganisation ist der Name einer Konferenzreihe mit einer langjährigen
Tradition, die von der Deutschen Sektion der International Society of
Knowledge Organization (ISKO) organisiert wird. Die 15. Konferenz dieser
Reihe, die an der Freien Universität Berlin stattfand, hatte ihren Schwerpunkt
im Bereich Wissensorganisation und Digital Humanities. Die Strukturierung von
und die Interaktion mit groĂźen Datenmengen ist ein zentrales Thema in den
Digital Humanities. In diesem Konferenzband werden verschiedene Aspekte der
Wissensorganisation in den Digital Humanities diskutiert, und die Autoren der
einzelnen Beiträge zeigen, wie die Digital Humanities mit Wissensorganisation
umgehen
