Data Delivery for the ESA Gaia Data Release 1

Authors:
Gonzalez-Nuñez Juan

The first ESA Gaia intermediate data release, DR1, scheduled to be published on 10th July 2016 will be readily available online through several software dissemination systems developed under the umbrella of the Coordination Unit 9 (CU9) as the Gaia Archive. These systems will both provide systems for direct access to Gaia data (simple forms, ADQL editor, visualisation applications, GAVIP plattform) as well as reliable services with open APIs and protocols that these systems use (VO TAP+, VOSpace). This will enable seamless delivery this data to third party applications. Delivery mechanisms will also ensure availability of data to data centres wishing to offer mirror services and open retrieval of full data products to the public. Being the first of his kind for an ESA mission, the Gaia archive has played a role in the data processing chain for the generation of the DR1 data products as the final queriable repository for processed catalogues. Included as ingestion procedures for the archive, data models conversion and data filtering have performed the last steps for the generation of Gaia catalogues in the very core of the Archive systems. Integration of these systems with CU9 validation procedures has created a testing platform where not only the scientific quality of the data, but the very reliability of the software systems hosting it is deeply tested. We will review the data release process from the archival point of view both the architecture of the software systems developed for DR1 as well as the operations workflow.
