“…They are traditional aspects of librarianship and are included in the Library and Information Sciences curricula, but they have acquired new meaning in the digital era because of the importance of metadata quality in digital repositories. 13 As a matter of fact the accuracy, completeness and consistency of metadata improve the interoperability among repositories and help build an effective digital infrastructure for knowledge dissemination (Park, 2009). …”

The open access movement in scholarly communication has grown considerably over the last ten years and it has driven an increase in the number of institutional repositories (IRs). New professional roles and skills had to be developed to secure effective IR management.Collection developmente expertise and metadata curation are regarded as strategic roles for repositories and therefore it is only logical for the library and information community to take on the responsibility for managing these digital archives. However, it has become clear that traditional librarian skills do not suffice anymore to run successful repositories. A richer set of skills is needed, including management and communication skills, technical skills, and expertise with regard to access rights and preservation of digital content.Referring to the work carried out by the SHERPA Project in the UK with regard to the skills set for repository staff, the authors performed a survey among repository managers in Italy to assess the educational and professional background of the repository managers and the skills set required to implement successful institutional repositories. Skills Set for Repository Managers -Results of a Survey in Italy 408 Liber Quarterly Volume 21 Issue 3/4 2012The survey findings show that the professional profile of the repository manager is a multiform and complex one. It requires cross-functional and highly specialised competencies. Italian repository managers are of the opinion that the skills required to promote the repository within the institution and those required to deal with copyright issues as the most essential skills repository managers should acquire and be trained for. Collection development and metadata expertise, familiarity with project management and expertise in repository workflow design are also highly rated. Technical skills are needed to deal with interoperability standards and protocols.In Italy academic curricula do not meet the repository managers' educational needs. Academic programmes should be developed to include communication, project management and team work skills and pay more attention to copyright issues. Until that time repository managers will have to spend a considerable part of their working lives on professional training and self-directed learning.

Background The burden of chronic disease is increasing, and research and quality improvement will be less effective if case finding strategies are suboptimal. Objective To describe an ontology-driven approach to case finding in chronic disease and how this approach can be used to create a data dictionary and make the codes used in case finding transparent. Method A five-step process: (1) identifying a reference coding system or terminology; (2) using an ontology-driven approach to identify cases; (3) developing metadata that can be used to identify the extracted data; (4) mapping the extracted data to the reference terminology; and (5) creating the data dictionary. Results Hypertension is presented as an exemplar. A patient with hypertension can be represented by a range of codes including diagnostic, history and administrative. Metadata can link the coding system

“…Metadata quality is a semantically slippery term. Park [30] suggested that the most commonly accepted criteria for metadata quality are completeness, accuracy, and consistence. Our work is focused on the last criterion.…”

Consistency is an essential aspect of the quality of metadata. Inconsistent metadata records are harmful: given a themed query, the set of retrieved metadata records would contain descriptions of unrelated or irrelevant resources, and would even do not contain some resources considered obvious. This is even worse in when the description of the location is inconsistent. Inconsistent spatial descriptions may yield invisible or hidden geographical resources that cannot be retrieved by means of spatially themed queri es. Therefore, ensuring spatial consistency should be a primary goal when reusing, sharing and developing georeferenced digital collections. We present a methodology able to detect geospatial inconsistencies in metadata collections based on the combination of spatial ranking, reverse geocoding, geographic knowledge organization systems, and information retrieval techniques. This methodology has been applied to a collection of metadata records describing maps and atlases belonging to the Library of Congress. The proposed approach was able to identify automatically inconsistent metadata records (870 out of 10,575) and propose fixes to most of them (91.5%) These results support that the proposed methodology could assess the impact of spatial inconsistency in the retrievability and visibility of metadata records and improve their spatial consistency.
