The document outlines the current state of the RRDG 'data sharing' specification, which was initiated in early 2019 and focuses on establishing a standard for per-registrar data sharing in a CSV format over HTTPS. It includes details on data fields related to registration metrics and lists ongoing open issues such as licensing and format requirements. Further steps involve addressing feedback, resolving open issues, and publishing final specifications for implementation by registries and registrars.

Transport
• HTTPS
 GET and HEAD
 „download“, Filename „metrics-<tld>-<type>-<start>-<end>.csv“
• URL
 https://<host>/<prefix>/v1/
• Query Parameters
 type: „monthly“, „daily“
 Start: Beginning of reporting period, eg. „2019-01-01“
 End: End of reporting period, eg. „2019-09-30“

Issues
• Licence? (As open as reasonable..!)
• Reporting Periods: Local times vs UTC
• Restrict format for date/time (ISO8601 subset?)
• BOM? Do we need it? Does it help in Excel-imports?
• Should files include „incomplete“ periods if requested?
• File name to include registrar/client info?
• Monthly / daily: Query parameter, or seperate URL?
• Authentication: More specific methods?
• „Custom fields“: Allow in specs?
• Consider option to publish „registry totals“?
• See https://github.com/alex-nicat/rrdg-data-sharing/issues
