Breaking: fyi.frontpage lexicon

[tom-sherman]

Status of this RFC: accepted

Overview

We intend to change the Frontpage lexicon NSID prefix from fyi.unravel.frontpage to fyi.frontpage as well as make a number of backwards incompatible changes to schema.

After a period of deprecation, new posts/comments/votes on the old NSID won't be consumed within the AppView.

The schema changes are described in #232

Why?

The unravel.fyi lexicon was used while we were testing, it's time for a stable lexicon schema and NSID to last us long term. We also want to unlock some additional features (described in #232)

How?

• Gather feedback on the plan and move this proposal to "accepted"
• Merge BREAKING: Stable frontpage lexicon #232 and publish lexicons to atproto using lexicon resolution
• Implement support for ingesting new lexicon in Frontpage AppView for testing
• Enter a communication phase where we advertise change to folks that may be using the lexicon. During this period nothing will change
• Change frontend to start creating new record types. This is when the new lexicon becomes the primary source, old lexicon is now deprecated. Apps using the old lexicon need to updated or otherwise they will not receive new Frontpage content. Key date: TBC
• Some time later we'll run a record migration process to move user's records (of the users we have active sessions for) to the new NSID. New records will maintain the existing rkey
