Improving data, metadata and service quality within Résif-SI

<p>R&#233;sif, the French seismological and geodetic network, was launched in 2009 in an effort to develop, modernize, and centralize geophysical observation of the Earth&#8217;s interior. This French research infrastructure uses both permanent and mobile instrument networks for continuous seismological, geodetic and gravimetric measurements.</p><p>R&#233;sif-SI is the Information System that manages, validates and distributes seismological data from R&#233;sif.</p><p>The construction of R&#233;sif-SI has lead to a federated organisation gathering several data and metadata producers (Nodes) and a national Seismological Data Centre.</p><p>The R&#233;sif Seismological Data Centre is one of 19 global centres distributing data and metadata in formats and using protocols which comply with International Federation of Digital Seismograph Networks (FDSN) standards. It is also one of the eleven nodes in EIDA, the European virtual data centre and seismic data portal in the European Plate Observing System (EPOS) framework.</p><p>Inside R&#233;sif-SI, each Node has it's specificities and dedicated procedures in order to manage and validate the data and metadata workflow from the station instruments to the R&#233;sif Seismological Data Centre.</p><p>To meet the expectations and needs of the end user in terms of data quality, metadata consistency and service availability, R&#233;sif-SI operates a complex set of quality enhancement operations.</p><p>This contribution will present the quality expectations that are in the core of R&#233;sif-SI, and show the methods and tools that help us meeting the expectations, and that could be of interest for the rest of the community.</p><p>We will then list some of our quality improvement projets and the expected results.</p>
