Twenty five colleagues from ENVRIplus, AnaEE, ICOS and eLTER met in Paris on October 11-13. The discussions focused on the use of semantics in RI Information Systems and on the development of shared solutions from ENVRIplus activities (photo © AnaEE).
ENVRIplus Theme 2 (Data for Science) organises a series of face2face meetings with RIs. Five ENVRIplus colleagues joined this AnaEE-ENVRIplus meeting in addition to the representatives of ecosystems RIs. AnaEE was mostly represented by AnaEE-France but also by colleagues from Belgium, England and Italy.
The meeting was introduced by general presentations of a) ENVRIplus theme 2, b) AnaEE-RI and c) the overall architecture of AnaEE Information System (IS). Four other sessions were devoted to semantics in RIs: 1) vocabularies (thesaurus and ontology) used by eLTER, ICOS and AnaEE, 2) standards for semantics, 3) semantic annotations and exploitation of the annotated resources.
AnaEE Information System is based on distributed resources (databases, modelling platforms), discoverable and accessible through metadata portals. The interoperability among these components relies on semantics. In AnaEE, both data and metadata are annotated. The annotation at the data level is not the general rule in the others RI where semantics is most often restricted to metadata. Data annotation allows for a larger set of exploitation possibilities but also generates larger amount of triples and specific Big Data issues.
The sharing of vocabularies, their alignments and the sharing of implementation practices are the main challenges for the exploitation of data across RI. The contributions of AnaEE to ENVRIplus activities were analysed for each identified topic: identification/citation of data sets, processing, optimization, curation, cataloguing, and provenance. The use of the ENVRIplus Reference Model for global RI modelling and the matching of the high-level ontology OIL-E with the domain ontologies used by RI were also discussed.
