MERLIN (Metadata Enrichment for Repositories in a London Institutional Network). Final project report.
MERLIN grew out of an interest in exploring the cost-effective integration of automatic subject description in eprints repositories. Primarily, the project wished to demonstrate opportunities for using the tools produced by NaCTeM, the National Centre for Text Mining, over repository full text. The project additionally sought to explore opportunities for improving repository discovery through interactions between text-mined keywords and on-line thesauri, specifically the HILT tools.
MERLIN used the London Universities aggregation service, LASSO, to demonstrate term extraction and thesaurus integration with full text repository content. A user interface was developed to support the extended functionality. Formative evaluation, user testing and final evaluation all preceded the release of an open source, re-usable web application, to allow the MERLIN metadata enrichment technology to be incorporated into any repository on any platform
Anti-pattern Free Code-first Web Services for State-of-the-art Java WSDL Generation Tools
Service-Oriented Computing (SOC) promotes structuring applications via coarse-grained, remote components called services. To materialise SOC, web services is the most common choice. A web service comprises an implementation and a description using the Web Services Description Language (WSDL). Web services are often built by first implementing their behaviour and then generating its WSDL document via automatic tools. However, bad design practices already present in a service implementation may end up affecting the quality of its WSDL document. For web services to be reusable, good WSDL designs are crucial. Previously, Mateos et al. show that there is a high correlation between Object-Oriented (OO) metrics from service implementations and the occurrences of 'anti-patterns' in WSDL documents. In this follow-up paper, these results are extended to all the existing WSDL generation tools. A detailed analysis of the impact of OO metric-driven code refactorings on the quality of WSDL documents is also reported.Fil: Ordiales Coscia, JosĂ© Luis.

Telescope Bibliographies: an Essential Component of Archival Data Management and Operations
Assessing the impact of astronomical facilities rests upon an evaluation of
the scientific discoveries which their data have enabled. Telescope
bibliographies, which link data products with the literature, provide a way to
use bibliometrics as an impact measure for the underlying data. In this paper
we argue that the creation and maintenance of telescope bibliographies should
be considered an integral part of an observatory's operations. We review the
existing tools, services, and workflows which support these curation
activities, giving an estimate of the effort and expertise required to maintain
an archive-based telescope bibliography.Comment: 10 pages, 3 figures, to appear in SPIE Astronomical Telescopes and

Semantic enrichment for enhancing LAM data and supporting digital humanities. Review article
With the rapid development of the digital humanities (DH) field, demands for historical and cultural heritage data have generated deep interest in the data provided by libraries, archives, and museums (LAMs). In order to enhance LAM data’s quality and discoverability while enabling a self-sustaining ecosystem, “semantic enrichment” becomes a strategy increasingly used by LAMs during recent years. This article introduces a number of semantic enrichment methods and efforts that can be applied to LAM data at various levels, aiming to support deeper and wider exploration and use of LAM data in DH research. The real cases, research projects, experiments, and pilot studies shared in this article demonstrate endless potential for LAM data, whether they are structured, semi-structured, or unstructured, regardless of what types of original artifacts carry the data. Following their roadmaps would encourage more effective initiatives and strengthen this effort to maximize LAM data’s discoverability, use- and reuse-ability, and their value in the mainstream of DH and Semantic Web

COBOL systems migration to SOA: Assessing antipatterns and complexity
SOA and Web Services allow users to easily expose business functions to build larger distributed systems. However, legacy systems - mostly in COBOL - are left aside unless applying a migration approach. The main approaches are direct and indirect migration. The former implies wrapping COBOL programs with a thin layer of a Web Service oriented language/platform. The latter needs reengineering COBOL functions to a modern language/ platform. In our previous work, we presented an intermediate approach based on direct migration where developed Web Services are later refactored to improve the quality of their interfaces. Refactorings mainly capture good practices inherent to indirect migration. For this, antipatterns for WSDL documents (common bad practices) are detected to prevent issues related to WSDLs understanding and discoverability. In this paper, we assess antipatterns of Web Services’ WSDL documents generated upon the three migration approaches. In addition, generated Web Services’ interfaces are measured in complexity to attend both comprehension and interoperability. We apply a metric suite (by Baski & Misra) to measure complexity on services interfaces - i.e., WSDL documents. Migrations of two real COBOL systems upon the three approaches were assessed on antipatterns evidences and the complexity level of the generated SOA frontiers - a total of 431 WSDL documents.Fil: Mateos Diaz, Cristian Maximiliano.

OSGeo conference videos as a resource for scientific research: The TIB|AV Portal
This paper reports on new opportunities for research and education in Free and Open Source Geoinformatics as a translational part of Open Science, enabled by a growing collection of OSGeo conference video recordings at the German National Library of Science and Technology (TIB). Since 2015, OSGeo conference recordings have been included to the collection sphere of TIB in information sciences. Currently, video content from selected national (FOSSGIS), regional (FOSS4G-NA) and global (FOSS4G) conferences is being actively collected. The annual growth exceeds 100 hours of new content relating to the OSGeo software projects and the OSGeo scientific-technical communities. This is seconded by retrospective acquisition of video material dating from past conferences, going back until 2002 to preserve this content, ensuring both long term availability and access. The audiovisual OSGeo-related content is provided through the TIB|AV Portal, a web-based platform for scientific audiovisual media providing state-of-the art multimedia analysis and retrieval. It implements the requirements by research libraries for reliable long term preservation. Metadata enhancement analysis provides extended search and retrieval options. Digital Object Identifiers (DOI) enable scientific citation of full videos, excerpts and still frames, use in education and also referral in social networks. This library-operated service infrastructure turns the audiovisual OSGeo-related content in a reliable source for science and education
