First thoughts on a domain-specific-language (DSL) for defining Fedora open badges a la https://fedoraproject.org/wiki/Open_Badges

bodhi-update-fancy.yaml

%YAML 1.2
---

# This is some metadata about the badge
name:           The Zen of Foo Bar Baz
description:    Your packaging efforts refer to a meta-syntactic variable.
creator:        ralph

# This is a link to the discussion about adopting this as a for-real badge.
discussion: http://github.com/fedora-infra/badges/pull/SOME_NUMBER

# Here we'll run our check if the message that we receive is in either the
# 'bodhi' or the 'git' categories.
trigger:
  category:
    any:
      - bodhi
      - git

# Once the check has been triggered, this defines what we actually check.
# Here we check datanommer for all messages which
#   belong to the user of the message we just received.
#   have the same topic as that message
#   and which have ANY of the strings 'foo', 'bar', 'baz' anywhere in the body.
# If there are at least one of those message in the db, then aware the badge.
criteria:
  datanommer:
    - filter:
        all:
          topic: "{{topic}}"
          raw_contains:
            any:
              - foo
              - bar
              - baz
      operation: count
      must be:
        greater than or equal to: 1
