• bug tracking

• wiki

• etc

Veracity

• decentralized database

• template driven merge

  • automerge based on rules in the template

    • Json (json.org)

    • automerge is correct if the template defines it to be correct

    • possible to define a template such that automerge never fails

    • log of automerge changes

    • conflicting changes

      • two people modify the same record and field

        • most recent

        • highest value

        • resolve by group (dev vs qa)

    • unique constrains

      • GUIDs

        • concatenate a level 1 UUID and level 4 UUID

        • not a friendly id

      • uniqify

        • on merge, if a merge result violates unique constraint, the template defines the resolution

      • create friendly ids, then uniqify if necessary

        • userid + incrementing integer

        • if conflict, increment integer again
