SKAO (Square Kilometre Array Observatory; Australia & South Africa)

The SKAO is already in the active construction phase. The science verification phase for Array Assembly 2, AA2, composed of 64-station and 64-dish arrays in the two locations, is expected for Q3/Q4 2026. The SKA Regional Centres Network (SRCNet) is in the transition from prototyping to development phases, with the science verification phase milestone as the target for a simplified but open-to-the-community science platform.

During the last period, the SRCNet has been involved in several IVOA initiatives, in particular the ones related to the interoperability and connection between science platform nodes (required for the SRCNet federated deployment). SRCNet is participating in the leading of the Execution Planner standardisation and identifying other ways to transparently connect astronomical science platforms allowing heterogeneous local software stacks.

The SRCNet is making use of IVOA standards in its design and in its prototypes. The Data Management System prototypes include ObsCore TAP discovery services and metadata associated with the data using IVOA data models. Also, the Identity & Access Management (IAM) including Single Sign-on is designed to accept different identity providers and the Group Membership System makes use of the IVOA GMS protocol.

Apart from its active participation in the IVOA GWS WG, the SRCNet members are increasing their involvement in the IVOA Radio IG so radio data is better integrated into the IVOA context.
