## GitHub's Repository Ownership Problem

GitHub had over 14,000 repositories, many of which lacked a clear owner. This ambiguity, especially for repositories not tied to production services, caused issues in security and workflow efficiency.

## The Old Ownership Model

GitHub tracked ownership for production services through its Service Catalog. However, this model did not apply to many repositories, leading to frequent ownership ambiguities.

## The Secret Scanning Issue

During secret scanning cleanup, finding repository owners took too much time. This uncertainty risked security workflows and slowed down processes.

## The New Ownership Model

GitHub decided to make repository ownership a first-class property. Using custom properties, ownership type and owner name were defined for each repository, facilitating enterprise policy enforcement.

## Ownership Types

The new model defined three ownership types: Service Catalog, Hubber Handle (GitHub employee), and Team. These types covered all repositories at GitHub.

## Automatic Synchronization

An automatic sync was established between the Service Catalog and repository custom properties. This automated ownership determination for service-backed repositories, reducing workload.

## Implementation Process

Ownership enforcement was initiated using GitHub App and Kubernetes CronJob. Repositories without ownership were archived after a 30-day grace period, offering a reversible and non-destructive solution.

## Initial Implementation Experience

The first implementation caused issues as many repositories lacked ownership. However, this process made GitHub employees more aware of ownership responsibilities.

## Outcome and Importance

GitHub's new ownership model improved repository management, enhancing security workflows and corporate efficiency. It also helped prevent similar issues in the future.
