Preamble The SKA Board has recently endorsed the concept of SKA Regional Centres (SRCs) as its preferred model for meeting and managing the challenges posed by the extremely high data rates, data volumes and data analysis requirements of SKA Phase 1. Currently, the project is limited to the basic data products created by the Science Data Processor, stored locally in data processing facilities in the Host Countries (AUS/RSA). The scientific success of the SKA is dependent on a viable data management plan for the long-term (50+ years) curation and exploitation of the data products and the infrastructure necessary to achieve this.

Essential Functions of Regional Centres provide access to SKA data products, subject to SKA data access policies; provide the computational resources for processing, including science analysis and data visualization; provide a common platform for the continued development and certification of software and data analysis tools; provide a long-term science archive for SKA data products; and provide local user support to their communities.

SRCCG remit define a minimum set of requirements for individual SRCs; develop a set of requirements for the SRC network as a whole, including plans for the physical network connecting SRCs, both together and with the SKAO sites; develop the requirements for implementing an SKA data archive; identify the requirements for, and coordinate the development of, technical interfaces between the SRCs and the SKA; draft the MoU to be agreed between the SRCs and the SKA Observatory that accept the stated minimum requirements and SKA data access policies;

SRCCG remit (continued) develop a set of data challenges to test and verify the capabilities and resources of each SRC, as well as the SRC network; develop an accreditation process for the SRCs, including branding and appearance policies; develop a process to ensure that software tools are interoperable across the SRC network; develop a policy for the inclusion of user-generated advanced data products into the SRC archive; develop SKA data heritage and access policies to that heritage data set for approval by the SKAO; and investigate models for the future governance of the collaborative network of SRCs.
