From Data Archives to Science Gateways: examples of INAF-supported radio facilities.

Abstract

Data archives are now rapidly evolving from simple repositories to sophisticated science gateways, facilitating data discovery, access, retrieval, visualization, processing, interoperability (with data at different wavelengths or from different messengers), and reuse. This transformation is driven by the increasing volume and complexity of data generated by modern radio astronomy facilities, which offer unprecedented potential for scientific discovery.

INAF has been at the forefront of this evolution, actively embracing Open Science principles, through supporting various initiatives promoted by the International Virtual Observatory Alliance (IVOA) in developing and implementing new standards. From the perspective of the radio astronomical facilities I am working with, I will present some examples of e-infrastructures or projects at various scales, including:

• The INAF Radio Telescope Data Archive, a newly operational archive providing access to a wealth of radio astronomical data. In such a context, I will also briefly address the INAF contribution to the IVOA Radio Interest Groups (RIG), which recently proposed an extension of the ObsCore Data Model (ObsCore DM) for bolstering the discovery of radio data.
• The Additional Representative Images for Legacy (ARI-L) project, leaded by the Italian node of the ALMA Regional Centre: this project reprocessed ALMA data from earlier cycles (2-4) in order to support archival science projects, hence adding value to the ALMA Science Archive (ASA) itself.
• The deployment of the Italian node of the SKA Regional Centre Network (SRCNet): the Team Orange established by the SRC Steering Committee (SRCSC) has been working on a prototype for data visualization, and recently changed its focus towards deployment activities, since Italy will host one of the first 9 nodes of the SRCNet.
