# `Backplane.JsonSchema.Draft7.Dialect`

Identifies the Draft 7 meta-schema and the keywords defined by that draft.

Draft 7 predates `$vocabulary`, so it uses a keyword set rather than the
Draft 2020-12 vocabulary URI map.

# `base_uri`

Returns the Draft 7 meta-schema URI without a fragment.

# `builtin_schema?`

Recognizes the canonical Draft 7 meta-schema URI, with or without `#`.

# `keyword?`

Returns whether a keyword belongs to Draft 7. Unknown keywords are annotations.

# `schema_uri`

Returns the canonical Draft 7 meta-schema URI.
