  • Linkedpipes DCAT-AP Viewer: a Native DCAT-AP Data Catalog⋆
    LinkedPipes DCAT-AP Viewer: A Native DCAT-AP Data Catalog? Jakub Klímek[0000−0001−7234−3051] and Petr Škoda[0000−0002−2732−9370] Charles University, Faculty of Mathematics and Physics Malostranské nám. 25, 118 00 Praha 1, Czech Republic [email protected] Abstract. In this demonstration we present LinkedPipes DCAT-AP Viewer (LP-DAV), a data catalog built to support DCAT-AP, the Eu- ropean standard for representation of metadata in data portals, and an application profile of the DCAT W3C Recommendation. We present its architecture and data loading process and on the example of the Czech National Open Data portal we show its main advantages compared to other data catalog solutions such as CKAN. These include the support for Named Authority Lists in EU Vocabularies (EU NALs), controlled vocabularies mandatory in DCAT-AP, and the support for bulk loading of DCAT-AP RDF dumps using LinkedPipes ETL. Keywords: catalog · DCAT · DCAT-AP · linked data 1 Introduction Currently, two worlds exist in the area of data catalogs on the web. In the first one there are a few well established data catalog implementations such as CKAN or DKAN, each with their data model and a JSON-based API for accessing and writing the metadata. In the second one, there is the Linked Data and RDF based DCAT W3C Recommendation [1] and its application profiles, such as the European DCAT-AP1, which are de facto standards for representation of metadata in data portals. The problem is that CKAN has been around for a while now, and is better developed, whereas DCAT is still quite new, with insufficient tooling support, nevertheless it is the standard.

The strategic initiative EnviDat highlights the importance WSL lays on Research Data Management (RDM) at the institutional level and demonstrates the commitment to accessible research data in order to advance environmental science. EnviDat focuses on registering and publishing environmental data sets and provides unified and efficient access to the WSL’s comprehensive reservoir of environmental monitoring and research data. Research data management is organized in a decentralized manner where the responsibility to curate research data remains with the experts and the original data providers. EnviDat supports data producers and data users in registration, documentation, storage, publi- cation, search and retrieval of a wide range of heterogeneous data sets from the environmental domain. Innovative features include (i) a flexible, three-layer metadata schema, (ii) an additive data discovery model that considers spatial data and (iii) a DataCRediT mechanism designed for specifying data authorship.

  • Towards a Harmonized Dataset Model for Open Data Portals
    HDL - Towards a Harmonized Dataset Model for Open Data Portals Ahmad Assaf1;2, Rapha¨elTroncy1 and Aline Senart2 1 EURECOM, Sophia Antipolis, France, <[email protected]> 2 SAP Labs France, <[email protected]> Abstract. The Open Data movement triggered an unprecedented amount of data published in a wide range of domains. Governments and corpo- rations around the world are encouraged to publish, share, use and in- tegrate Open Data. There are many areas where one can see the added value of Open Data, from transparency and self-empowerment to improv- ing efficiency, effectiveness and decision making. This growing amount of data requires rich metadata in order to reach its full potential. This meta- data enables dataset discovery, understanding, integration and mainte- nance. Data portals, which are considered to be datasets' access points, offer metadata represented in different and heterogenous models. In this paper, we first conduct a unique and comprehensive survey of seven meta- data models: CKAN, DKAT, Public Open Data, Socrata, VoID, DCAT and Schema.org. Next, we propose HDL, an harmonized dataset model based on this survey. We describe use cases that show the benefits of providing rich metadata to enable dataset discovery, search and spam detection. Keywords: Dataset Metadata, Dataset Profile, Dataset Model, Data Quality 1 Introduction Open data is the data that can be easily discovered, reused and redistributed by anyone. It can include anything from statistics, geographical data, meteo- rological data to digitized books from libraries. Open data should have both legal and technical dimensions. It should be placed in the public domain un- der liberal terms of use with minimal restrictions and should be available in electronic formats that are non-proprietary and machine readable.

  • Dynamic Data Citation Service—Subset Tool for Operational Data Management
    data Article Dynamic Data Citation Service—Subset Tool for Operational Data Management Chris Schubert 1,* , Georg Seyerl 1 and Katharina Sack 2 1 Data Centre—Climate Change Centre Austria, 1190 Vienna, Austria 2 Institute for Economic Policy and Industrial Economics, WU—Vienna University of Economics and Business, 1020 Vienna, Austria * Correspondence: [email protected] Received: 31 May 2019; Accepted: 30 July 2019; Published: 1 August 2019 Abstract: In earth observation and climatological sciences, data and their data services grow on a daily basis in a large spatial extent due to the high coverage rate of satellite sensors, model calculations, but also by continuous meteorological in situ observations. In order to reuse such data, especially data fragments as well as their data services in a collaborative and reproducible manner by citing the origin source, data analysts, e.g., researchers or impact modelers, need a possibility to identify the exact version, precise time information, parameter, and names of the dataset used. A manual process would make the citation of data fragments as a subset of an entire dataset rather complex and imprecise to obtain. Data in climate research are in most cases multidimensional, structured grid data that can change partially over time. The citation of such evolving content requires the approach of “dynamic data citation”. The applied approach is based on associating queries with persistent identifiers. These queries contain the subsetting parameters, e.g., the spatial coordinates of the desired study area or the time frame with a start and end date, which are automatically included in the metadata of the newly generated subset and thus represent the information about the data history, the data provenance, which has to be established in data repository ecosystems.

  • Analysis of Current RDM Applications for the Interdisciplinary Publication of Research Data
    Analysis of current RDM applications for the interdisciplinary publication of research data Andr´eLanger[0000−0001−7073−5377], Ellen Bilz, and Martin Gaedke[0000−0002−6729−2912] Chemnitz University of Technology, Germany (andre.langer, ellen.bilz, martin.gaedke)@informatik.tu-chemnitz.de Abstract. The digital transformation of science allows researchers nowa- days to expose Research Objects through many different publishing channels, so that other interested stakeholders can find and reuse it. Linked Data is an accepted mean in these meta descriptions to enhance Findability, Accessibility, Interoperability and Reusability (FAIR). But researchers face a large variety of established publishing applications, where they have to select between general-purpose or domain-specific platforms and user interfaces of varying quality and feature set. In order to improve interoperability aspects, we want to analyze which publishing systems currently exist and to which extent they support Linked Data annotations from the very beginning. We therefore concentrated on research data and conducted a systematic mapping of general-purpose research data management (RDM) systems currently in use, and summarize them in a tabular resource. The obtained results were then evaluated against their current support for semantic, interdisciplinary data annotation and exchange. We show, that a large set of established research data publishing solutions already exists, but that their support for Linked Data is still limited and can be improved. Keywords: Research Data Management, Data Publishing, FAIR, Linked Data, Systematic Mapping 1 Introduction Scientists are encouraged to publish, share and reuse research data (Open Re- search, stimulating Open Data and Open Access). Research data (other terms: scientific data, scholarly data) is an essential artifact of scientific work: It leads to insights, makes research reproducible and validates findings.

  • Geospatial Open Data Usage and Metadata Quality
    International Journal of Geo-Information Article Geospatial Open Data Usage and Metadata Quality Alfonso Quarati 1 , Monica De Martino 1,* and Sergio Rosim 2 1 Institute for Applied Mathematics and Information Technologies National Research Council, 16149 Genoa, Italy; [email protected] 2 Instituto Nacional de Pesquisas Espaciais, Sao Jose dos Campos 12230-081, Brazil; [email protected] * Correspondence: [email protected] Abstract: The Open Government Data portals (OGD), thanks to the presence of thousands of geo- referenced datasets, containing spatial information are of extreme interest for any analysis or process relating to the territory. For this to happen, users must be enabled to access these datasets and reuse them. An element often considered as hindering the full dissemination of OGD data is the quality of their metadata. Starting from an experimental investigation conducted on over 160,000 geospatial datasets belonging to six national and international OGD portals, this work has as its first objective to provide an overview of the usage of these portals measured in terms of datasets views and downloads. Furthermore, to assess the possible influence of the quality of the metadata on the use of geospatial datasets, an assessment of the metadata for each dataset was carried out, and the correlation between these two variables was measured. The results obtained showed a significant underutilization of geospatial datasets and a generally poor quality of their metadata. In addition, a weak correlation was found between the use and quality of the metadata, not such as to assert with certainty that the latter is a determining factor of the former.
