GeoERA Information Platform (GIP), geoscientific information from all over Europe in one place.

Abstract

<p>The GeoERA Information Platform Project (GIP-P) is establishing a new common platform for organising, disseminating and sustaining digital harmonised data from the GeoERA geoscientific projects on subsurface energy, water and raw material resources from all over Europe. The Platform is part of the EuroGeoSurveys’ European Geological Data Infrastructure (EGDI), which takes care of its future sustainability.</p><p>Great efforts are being put into making the data Findable, Accessible, Interoperable and Reusable (FAIR) at one place and thereby be as valuable as possible for the stakeholders.</p><p>The Platform consists of web applications, services, databases, digital repository, opensource tools and services that connect all together. The main components are:</p><p>EGDI Metadata Catalogue: It is based on the MIcKA system for management and publication of metadata on structured data and services. This technology enables entry, editing, harvesting, discovery, and view of metadata, including tools for compilation and export of metadata in standardized formats.</p><p>EGDI Central Database: Stores structured data for other main components in PostgreSQL. It contains geospatial data as well as configuration of various maps, layers, datasets uploaded by individual projects, metadata for unstructured documents and DOI-links, search system data, 3D models data, etc.</p><p>European Geoscience Registry: Stores and publishes controlled vocabularies for the whole GeoERA program which supports multilingual semantic text search and project specific knowledge concepts. It is a Linked Data Platform based on Jena RDF triple store.</p><p>Digital Archive: Stores unstructured data (PDF, DOI document links, images or comma separated files) and their metadata. It consists of a controlled part of the filesystem, the Solr search engine, the repository database and the thematic repository search web application that enables the user to perform an advanced search through the repository with auto-suggested terms from RDF triple store and ranked results. </p><p>Search System: Allows to discover geoscientific information from all of the above modules. Through a powerful search logic it allows to find datasets, see their metadata, access their available online distributions (specific representations of a dataset) and also select and display subsets of features from those datasets. Search results are ordered according to relevance.</p><p>The platform also contains modules for harvesting data in INSPIRE compliant formats, for disseminating geospatial data on web GIS, a 3D geological model viewer and modules for uploading data and for monitoring services.</p><p>The presentation will focus on describing the various components and their individual functions and in particular on how the search system interacts with all of them. This makes it possible to get useful results from the very diverse data sources from the system.</p>
