Constructor Details

#initialize(conformance: CHECKM_0_7, profile:, prefixes: {}, fields: [], entries: []) ⇒ Manifest

Creates a new manifest. Note that the prefix, field, and entry arrays are copied on initialization, as are the individual entry hashes.

Parameters:

  • conformance (String) (defaults to: CHECKM_0_7) —

    the conformance level. Defaults to CHECKM_0_7.

  • profile (URI, String) —

    the profile URI. Must begin with

  • prefixes (Hash{String,Symbol => URI, String}) (defaults to: {}) —

    a map from namespace prefixes to their URIs

  • fields (defaults to: []) —

    Array a list of field names, in the form prefix:fieldname

  • entries (Array<Hash<String, Object><] A list of entries, each of which is a hash keyed by a prefixed fieldname defined in `fields`. Nil values are allowed.) (defaults to: []) —

    ntries [Array<] A list of entries, each of which is a hash keyed by a prefixed fieldname defined in fields. Nil values are allowed.

Raises:

  • (ArgumentError) —

    if profile does not begin with PROFILE_BASE_URI

  • (ArgumentError) —

    if fields cannot be parsed as prefix:fieldname, or if one or more prefixes is not mapped to a URI in prefixes

  • (URI::InvalidURIError) —

    if profile cannot be parsed as a URI
