- KonferenzbeitragA Common Reference Model for Environmental Science Research Infrastructures(Proceedings of the 27th Conference on Environmental Informatics - Informatics for Environmental Protection, Sustainable Development and Risk Management, 2013) Chen, Yin; Martin, Paul; Magagna, Barbara; Schentz, Herbert; Zhao, Zhiming; Hardisty, Alex; Preece, Alun; Atkinson, Malcolm; Huber, Robert; Legré, YannickIndependent development of research infrastructures leads to unnecessary replication of technologies and solutions whilst the lack of standard definitions makes it difficult to relate experiences in one infrastructure with those of ot hers. The ENVRI Reference Model, www.envri.eu/rm, uses the Open Distributed Processing standard framework in order to model the "archetypical" environmental research infrastructure. The use of the ENVRI -RM to illustrate common characteristics of European ESFRI environmental infrastructures from a number of different perspectives provides a common language for and understanding of environmental research infrastructures, promote technology and solution sharing between infrastructures, and improve interoperability between implemented services .
- KonferenzbeitragData Integration in the Field of Environmental Monitoring(Environmental Communication in the Information Society - Proceedings of the 16th Conference, 2002) Briesen, Marcus; Hofmann, Claus; Otterstätter, Arnd; Nikolai, Ralf; Mirtl, Michael; Schentz, Herbert; Vogel, WilhelmIn order to improve the quality of the environment national and international legislation increasingly asks for monitoring systems as an appropriate basis for decision making at all levels. The fundamental basis for all decisions is an integrated access to data from various programmes, databases, provinces, states etc. In this article we analyze the needs and requirements of data integration based on the examples of the water framework directive and integrated monitoring. Depending on the power of the local systems already in place we suggest two different ways of fulfilling these requirements: 1.) Providing a system that has a common user interface and various data connectors to access existing data in a uniform way. 2.) To establish a super database for (nearly) any kind of environmental data. A combination of both approaches would provide a tool kit which significantly decreases the effort for integration of existing and new data including uniform, polysemantic views and enabling substantial analysis and reporting.
- KonferenzbeitragEnvThes – interlinked thesaurus for long term ecological research, monitoring, and experiments(Proceedings of the 27th Conference on Environmental Informatics - Informatics for Environmental Protection, Sustainable Development and Risk Management, 2013) Schentz, Herbert; Peterseil, Johannes; Bertrand, NicThe long term ecological research and monitoring is resulting in a vast amount of data describing environmental characteristics, drivers and pressures. Despite harmonisation efforts in the field of methods and observation designs within the frame of LTER Europe or other related networks, different management solutions, together with a varying set of terms and concepts describing the data, are often used for local data management. Therefore, there is not only the need for syntactic but also semantic harmonisation in order to ensure data exchange for cross site and cross domain analysis. The use of a common controlled vocabulary or thesaurus is the first step to enable semantic harmonisation across a network of sites. Within the European scale projects EnvEurope (LIFE08 ENV/IT/00399) and ExpeER the development of a controlled vocabulary for long term ecological research and monitoring was started in order to provide a common set of terms and concepts used in this domain. It is called EnvThes and implemented as SKOS/RDF based thesaurus using poolParty as management tool. PoolParty offers a web browser based viewing and editing interface, as well as a linkedData interface and a SPARQL endpoint. EnvThes is based on existing vocabularies, like US-LTER controlled vocabulary, EUNIS Habitat list, Catalogue of Life, NASA Units, extended by concepts which are additionally needed. Links to the original sources and to matching concepts within commonly used thesauri like EUROVOC, GEMET, AGROVOC or EarTh are established, thus overcoming the islands of conceptual models, developed for different purposes. These links to slowly changing vocabularies, like EUROVOC or GEMET are the anchors for stable semantics; and the LTER specific concepts, for which no linkable equivalent can be found in those thesauri, are the building blocks of a flexible conceptual model, needed by science. EnvThes provides keywords for the metadata system DEIMS, and is used for semantic annotation of the data in the EnvEurope data repository. It can additionally be used as source of terms and links to concepts for any sort of document (for example a Microsoft Excel spreadsheet, Word document, PowerPoint presentation, LATEX document, etc.) used in the LTER context.
- KonferenzbeitragLOD-ready Environmental Terminology with iQvoc(Innovations in Sharing Environmental Observations and Information, 2011) Bandholtz, Thomas; Fock, Joachim; Wolff, Astrid; Schentz, HerbertiQvoc is a new open source tool for maintaining and publishing domain terminologies on the Web following the “Linking Open Data” (LOD) pattern. This article gives a short overview of the underlying principles and introduces three environmental terminologies which have been deployed with iQvoc, each of them with its own characteristics.
- KonferenzbeitragMonitoring of Environmental Status through Long Term Series: Data Management System in the EnvEurope Project(EnviroInfo Dessau 2012, Part 1: Core Application Areas, 2012) Oggioni, Alessandro; Carrara, Paola; Kliment, Tomas; Peterseil, Johannes; Schentz, HerbertThe last innovations in the information science have improved developing systems relating to the creation, collection, storage, processing, modelling, interpretation, display and dissemination of data and information focused on Environmental Science (Page and Wohlgemuth, 2010). International initiatives such as SEIS (Shared Environmental Information System), GMES (Global Monitoring Environmental and Security), GEOSS (Global Earth Observation System of Systems); projects like Humboldt, NatureSDIplus, BioFresh, GIGAS; consortia such as GBIF (Global Biodiversity Information Facility), LifeWatch, DataONE (Data Observation Network for Earth) and OGC (Open Geospatial Consortium) and finally legal framework in Europe (INSPIRE - 2007/2/CE) and in United States (OMB Circular A-16 - 2002) stimulated effective implementation of an information technology innovations. A common feature consists of a development of an infrastructure, which facilitates discovery, evaluation and use of data, information and knowledge. Sharing of large datasets can establish a much deeper understanding for both nature and society, open up many new avenues of research or assist to policy-makers with relation to environmental policies. (AA.VV., 2011). Paper deals with issues related to an establishment of architecture for data exchange within the Long Term Ecological domain in Europe and propose solutions to resolve them in order to provide an interoperable system.
- KonferenzbeitragMORIS – MEDEA or Using Ecological Tools for Monitoring of Meteorological Extreme Events(Informatics for Environmental Protection - Networking Environmental Information, 2005) Schentz, Herbert; Schleidt, Katharina; König, Martin; Mirtl, MichaelMORIS is an information system originally designed for the Austrian part of the UN-ECE “Integrated Monitoring” program. The requirements of an information system for heterogeneous and changing data led us to an object relational data model, with a predefined core ontology and end user defined extensions. This information system has proven to be effective for many different ecological topics, so that we dare say that MORIS is a universal information system for ecological data. Due to our success using MORIS in various ecological fields, when the need of an information system for meteorological extreme events came up, we checked the suitability of MORIS. When we started analyzing this problem, it seemed that “event” is a very broad and imprecise concept, hard to model in a normalised manner. On more detailed analysis, we realized that nature driven events like heavy precipitation or an avalanche are quite similar to man driven events like a campaign or a sample. Once these general decisions have been reached, creating the end-user defined classes and importing the instances turned out to be just as easy as with the ecological topics This leads to our assertion that MORIS is an appropriate tool for monitoring natural ecological events, and that the object oriented data model is an appropriate data-model for data-integration.
- KonferenzbeitragDas objektrelationale Softwarepaket MORIS (MOnitoring and Research Information System)(Environmental Communication in the Information Society - Proceedings of the 16th Conference, 2002) Schentz, Herbert; Mirtl, MichaelMORIS is an object-relational information system for various kinds of environmental data: results of chemical analyses (in form of time-series), the outcome of assessments as well as descriptive word documents or PDF Files (for laws, standards, decrees ) and maps (GIS) and even sketches, photos, filmor sound-documents. Within predifined packages the user can create classes with their attributes and polyhierarchical relations to other classes without changing the database or application. A lot of surfing tools, adaptable import and export interfaces and a sophisticated selection tool help to easily access data. Thus MORIS is a system suitable for many areas of environmental research and control.
- KonferenzbeitragSemantics in Ecosystem Research and Monitoring(Innovations in Sharing Environmental Observations and Information, 2011) Schentz, Herbert; Peterseil, Johannes; Magagna, Barbara; Mirtl, MichaelThe field of ecology in general, and environmental assessment in particular, demands the sharing of knowledge, information and data. On the European level –on the legal basis of the INSPIRE directive - a framework has been established which enables public access to geo-data in a structurally harmonized way. However, for ecological data the temporal dimension is just as important as the spatial dimension. Some of the existing data integration approaches show that efforts are needed to extend structural harmonization and include semantic harmonization. The sharing of knowledge, information and data implies a common understanding of the meaning of terms and concepts. This requirement has been met by controlled vocabularies, such as species lists and other taxonomies or catalogues of domain terminologies, long before the first computer was built. Current IT technologies have adopted these concepts of controlled vocabularies, and established and published them in digital form, mostly via the world wide web. This has resulted in a lot of benefits, such as accessibility, shared editing and the usability of controlled vocabularies in all sorts of applications. Some of the most prominent vocabularies are GEMET, CORINE Land Cover classes, EUNIS habitat list, Catalogue of Life, SERONTO, OBOE, Observation and Measurement, just to name a few. Those controlled vocabularies can be used in various ways: - As reference lists for scientific publications: e.g.: looking up GEMET concepts in different European languages on the site of the EEA (EIONET) - To tag metadata with keywords using controlled vocabularies by e.g. inserting keywords into an ISO19115 compliant XML document, as demanded by the INSPIRE directive, using SoilThes as a source for the keywords. - Semantic based data management linking data and semantically enriched metadata, e.g. of Integrated Monitoring Austria using the information system MORIS. However, efficient use of these resources is still hampered by the lack of a standardized framework for their interlinkage. The need for such a framework is not specific to the field of ecology or science in general. It is a requirement for all domains dealing with the sharing of information, knowledge and data. Technologies based on internet technologies such as the emerging Linked Data approach are trying to meet this challenge. This article first focuses on the specific needs for the use of semantics in ecological monitoring and gives a rough overview of how these have been met so far, independent of IT solutions. Secondly, we describe some technical approaches to meet these requirements and outline how these approaches are applied to specific solutions. Then we give an outlook on how these solutions could become part of a larger network of linked ecological data.
- KonferenzbeitragSharing European soil information - Best practice contribution to INSPIRE -(Innovations in Sharing Environmental Observations and Information, 2011) Feiden, Katharina; Fulajtár, Emil; Dobos, Endre; Schentz, Herbert; Eberhardt, Einar; Baritz, Rainer; Figueiredo, Carlos; Huber, Sigbert; Klug, HermannThe GS SOIL best practice network comprises 34 project partners out of 18 European member states. It receives funding by the European Commission and the first two years of GS SOIL, starting in June 2009, were dedicated to the survey and the analysis of data availability and accessibility, the activities towards the GS SOIL metadata profile, the data model and the GS SOIL portal. The aim of the paper is to present the state of the art of the GS SOIL project and the ongoing activities to support the INSPIRE implementation in the soil domain, especially to the development of data specification for the annex III theme “soil (Feiden 2010A; see also GS SOIL Deliverables).
- KonferenzbeitragStrukturen und Funktionen zur Abbildung interdisziplinärer Langzeitprojekte im Bereich von Ökosystem-Monitoring und –Forschung: Der Weg zum Hauptmenü von MORIS / Das objektrelationale Softwarepaket MORIS(Environmental Communication in the Information Society - Proceedings of the 16th Conference, 2002) Mirtl, Michael; Schentz, HerbertOriginally, MORIS (Monitoring and Research Information System) was designed to store and provide all data gathered by the ecosystem-monitoring activities of the UNECE Integrated Monitoring Programme in Austria. Society, facing challenges like climate change or loss of biodiversity is in urgent need of reliable information on environmental trends and cause effect relationships. To fulfill this requirement ecosystem monitoring and research strongly depend on information systems capable of depicting the results of a wide range of disciplines in the long term. Such systems have to provide not only raw data but also information on the methodological and spatial designs and their changes (primary meta-information). Only a generic and comprehensive architecture (object-relational approach) will allow to avoid redundancies across disciplines while, at the same time, guaranteeing the capacity for continuous adoptions. Highly valuable information is usually hold by the persons involved in the process of data gathering and primary data assessment (personal memory, field protocols). To maintain access to this secondary meta-information an appropriate information system must provide tools for referencing actors, projects and archives anywhere in the system.
