    Applying semantics in the environmental domain: The TaToo project approach
    (Innovations in Sharing Environmental Observations and Information, 2011) Avellino, Giuseppe; Pariente Lobo, Tomás; Schimak, Gerald; Rizzoli, Andrea Emilio; Dihé, Pascal
    The EU FP7 TaToo project major aim is to bridge the resource discovery gap. This is a well know problem regarding, firstly, the difficulty of discovering resources available on the Web, secondly, the access and possibly the ‘visualisation’ of these resources once discovered. TaToo is trying to solve the problem through a framework (based on semantic concepts) able to store in a knowledge base, meta-information (or metadata) associated with resources. Meta-information is then used by TaToo during the resource discovery process. Meta-information is provided by end users while discovering resources or by resource owners and, as stored in a triplestore, it consists of RDF triples made of Domain Ontologies concepts. Meta-information knowledge base makes possible, together with a reasoner, a resource model for annotation, and a set of Domain Ontologies, a semantically-enhanced resource discovery process. The paper briefly shows the TaToo architecture focusing on the description of those components dealing with semantics. Then, it shows how semantics has been implemented, giving details on the Minimal Environmental Resource Model (MERM) and on the process of integrating Domain Ontologies to realise the ontology framework used in TaToo.

    Publishing Agro-Environmental Data to a Semantically Unified Environmental Information Space: a Case Study
    (Innovations in Sharing Environmental Observations and Information, 2011) Nesic, Sasa; Rizzoli, Andrea Emilio; Athanasiadis, Ioannis; Donatelli, Marcello
    Publishing environmental data to Linked Open Data (LOD) requires environmental data providers to adopt a set of universally recognized linked data principles. These principles enable syntactic integration of the linked data regardless of the data publisher and origin. However, these principles do not provide any mechanism for semantic integration and interoperability of the linked data. In order to turn the linked environmental data into a semantically unified environmental information space, the linked environmental data must be accompanied by conceptualized semantics defined in domain conceptualizations known as domain ontologies. Taking into account the linked data principles and domain ontologies we proposed a set of requirements and a data-publishing workflow for environmental data providers. In this paper we present a case study supporting our approach by delivering: 1) an agro-environmental domain ontology and 2) a supporting software system that realizes the proposed data-publishing workflow. We demonstrate the publishing workflow on publishing some example, agro-environmental resources provided by JRC MARS, which is one of the leading European institutions for monitoring agricultural resources founded by the European Commission.
