A Standards-based Data Catalogue integrating scientific, community-based and citizen science data across the Arctic

INTAROS is a Horizon 2020 research and innovation project developing an integrated Arctic Observation System by extending, improving, and unifying existing systems in the different regions of the Arctic. INTAROS integrates distributed repositories hosting data from ocean, atmosphere, cryosphere and land, including scientific, community-based monitoring (CBM) and citizen science (CS) data. Throughout the project, INTAROS has been working closely with several local communities and citizen science programs across the Arctic, to develop strategies and methods for ingestion of data into repositories enabling the communities to maintain and share data. A number of these CBM and CS data collections have been registered in the INTAROS Data Catalogue. Some of these collections are hosted and sustained by large international programs such as PISUNA, eBird, Secchi Disk Study and GLOBE Observer. Registration in the INTAROS Data Catalogue contributes to making these important data collections better known in a wider community of users with a vested interest in the Arctic. It also enables sharing of metadata through open standards for inclusion in other Arctic data systems. This catalogue is a key component in INTAROS, enabling users to search for data across the targeted spheres to assess their usefulness in applications and geographic areas. The catalogue is based on a world-leading system for data management, the Comprehensive Knowledge Archive Network (CKAN). With rich functionality offered out of the box combined with a flexible extension mechanism, CKAN allows for quickly setting up a fully functional data catalogue. The CKAN open-source community offers numerous extensions that can be used as-is or adapted to implement customised functionality for specific user communities. To hold additional metadata elements requested by the partners we modified the standard database schema of CKAN. The presentation will focus on the current capabilities and plans for sustaining and enhancing the INTAROS Data Catalogue.
