Abstract: The two fastest near infrared survey telescopes are UKIRT-WFCAM and VISTA. The data from both these instruments are being archived by Wide Field Astronomy Unit (WFAU) at the IfA, Edinburgh, using the same curation pipeline, with some instrument-specific processing. The final catalogs from these surveys will contain many tens of billions of detections. Data are taken for a range of large surveys and smaller PI programs. The surveys vary from shallow hemisphere surveys to ultra-deep single pointings with hundreds of individual epochs, each with a wide range of scientific goals, leading to a wide range of products and database tables being created. Processing of the main surveys must allow for the inclusion of specific high-level requirements from the survey teams, but automation reduces the amount of work by archive operators allowing a higher curation efficiency. The decision making processes which drive the curation pipeline are a crucial element for efficient archiving. This paper describes the main issues involved in automating the pipeline.
