Open Science is the combination of Open Data and Open Access leading to interoperability
of resources for science production. Fostering new science through interoperability is the
goal of the International Virtual Observatory Alliance (IVOA), whose standards provide the
framework to allow Open Science in Astronomy and Astrophysics.
Data Access, Discovery and Interoperability (DADI) is the ASTERICS work package dealing
with the dissemination of the Virtual Observatory (VO) standards and technologies, gathering
needs from the scientific community and ESFRIs requirements related to interoperability, and
stirring them into updates or additions to the VO scenario.
Within DADI, networking and discussion forums and training events for the ESFRI partners
(as well as for the general data providers) have been held, to put together the thinking heads
of the research infrastructure (RI) projects and the staff having VO knowledge. These events
initially brought the interoperability perspective to the large scientific collaborations and later
allowed to feel the pulse of how much of the VO technology was welcomed, used and
investigated by the RIs.
During the events, requirements and perspective on the open science scenario were brought
in by the projects and collaborations and discussed with VO knowledgeable people.
This contribution tries to summarise what was discussed in such a context, in terms of how
useful and practical resource interoperability is when a large collaboration has to intertwine it
with project requests.
