+# Triage in OpenSearch Core
 ## What Do We Do With These Labels Anyway?
 
 Across all repositories in opensearch-project, we have a process called “triage.” The goal of this process is to make sure repository owners and maintainers check new issues to understand them. First - we learn if the issue is security related (e.g. CVE), second - we understand if we have enough information to act on the issue, third - we re-label or respond on the issue. During triage we do not work on these issues, but instead just try to get the issue to a next step. Because the OpenSearch core repository (https://github.com/opensearch-project/OpenSearch) has so many different functions with different sets of contributors working on these functions, repo owners decided to treat these functions like separate repositories when triaging to get through the backlog faster and have more focus. There are a few maintainers that do triage in public (see https://meetup.com/OpenSearch to join) and there will be more coming.
