This repository is NO LONGER BEING MAINTAINED AND HAS BEEN ARCHIVED. This code and effort has been moved to https://github.com/afsc-gap-products/gap_products. For New FOSS documentation, see https://afsc-gap-products.github.io/gap_products/content/foss-intro.html. .

The gap_products repository supports code used to create tables in the GAP_PRODUCTS Oracle schema. These tables include the master production tables, tables shared with AKFIN, and tables publicly shared on FOSS.

This code was previously maintained by:

The code in this repository is regularly being updated and improved. Please refer to releases for finalized products and project milestones. The FOSS dataset is only updated once a year and may be slightly behind the GitHub repository. This metadata is regarding scripts and data last ran and pushed to the AFSC oracle on June 01, 2023.
