    EPOS is a Research Infrastructure plan that is undertaking the challenge of integrating data from different solid Earth disciplines and of providing a common knowledge-base for the Solid-Earth community in Europe, by implementing and managing a logically centralised catalog based on the CERIF model. The EPOS catalogue will contain the information about all the participating actors, such as Research Infrastructures, Organisations and their assets, in relationship with the people, their roles and their affiliation within the specific scientific domain. The catalogue will guarantee the discoverability of domain specific data, data products, software and services (DDSS) and enable the EPOS Integrated Core Services system to perform - on behalf of a end user – advanced operations on data as for instance processing and visualization. It will also foster the homogenisation of vocabularies, as well as supporting heterogeneous metadata. Clearly, the effort of accomodating the diversities across all the players needs to take into account of existing initiatives concerning metadata standards and institutional recommendations, trying to satisfy the EPOS requirements by incorporating and profiling more generic concepts and semantics. The paper describes the approach of the EPOS metadata working group, providing the rationale behind the integration, extension and mapping strategy to converge the EPOS metadata baseline model towards the CERIF entities, relationships and vocabularies. Special attention will be given to the outcomes of the mapping process between two elements of the EPOS baseline - Research Infrastructure and Equipment - and CERIF, by providing detailed insights and description of the two data models, of encountered issues and of proposed solutions.

    EPOS: a novel use of CERIF for data intensive science
    (euroCRIS, 2014-05-13)
    ;
    One of the key aspects of the approaching data-intensive science era is integration of data through interoperability of systems providing data products or visualization and processing services. Far from being simple, interoperability requires robust and scalable e-infrastructures capable of supporting it. In this work we present the case of EPOS, a plan for data integration in the field of Earth Sciences. We describe the design of its e-infrastructure and show its main characteristics. One of the main elements enabling the system to integrate data, data products and services is the metadata catalogue based on the CERIF metadata model. Such a model, modified to fit into the general e-infrastructure design, is part of a three-layer metadata architecture. CERIF guarantees a robust handling of metadata, which is in this case the key to the interoperability and to one of the features of the EPOS system: the possibility of carrying on data intensive science orchestrating the distributed resources made available by EPOS data providers and stakeholders.
