NAME

       JSON::Schema::Modern::Vocabulary::FormatAssertion - Implementation of the JSON Schema Format-Assertion
       vocabulary

VERSION

       version 0.605

DESCRIPTION

       Implementation of the JSON Schema Draft 2020-12 "Format-Assertion" vocabulary, indicated in metaschemas
       with the URI "https://json-schema.org/draft/2020-12/vocab/format-assertion" and formally specified in
       <https://json-schema.org/draft/2020-12/json-schema-validation.html#section-7>.

       Support is also provided for

       •   the    equivalent    Draft    2019-09    keyword,    indicated    in   metaschemas   with   the   URI
           "https://json-schema.org/draft/2019-09/vocab/format"      and       formally       specified       in
           <https://datatracker.ietf.org/doc/html/draft-handrews-json-schema-validation-02#section-7>.

       •   the       equivalent       Draft       7       keyword,       as      formally      specified      in
           <https://datatracker.ietf.org/doc/html/draft-handrews-json-schema-validation-01#section-7>.

       •   the      equivalent      Draft      6       keyword,       as       formally       specified       in
           <https://json-schema.org/draft-06/draft-wright-json-schema-validation-01#rfc.section.8>.

       •   the       equivalent       Draft       4       keyword,       as      formally      specified      in
           <https://json-schema.org/draft-04/draft-fge-json-schema-validation-00#rfc.section.7>.

       Assertion              behaviour              can               be               enabled               by
       "/json-schema.org/draft/2020-12/json-schema-core.html#rfc.section.8.1.2/referencing    this    vocabulary
       explicitly" in https: in a metaschema's $vocabulary keyword, or by  toggling  the  "validate_formats"  in
       JSON::Schema::Modern option.

       When the Format-Annotation vocabulary is specified (which is the default for the draft2020-12 metaschema)
       and  combined  with  the  "validate_formats"  option  set  to  true,  unimplemented formats will silently
       validate, but implemented formats will validate completely.  Note  that  some  formats  require  optional
       module dependencies, and the lack of these modules will generate an error.

       When  this vocabulary (the Format-Assertion vocabulary) is specified, unimplemented formats will generate
       an error on use.

       Overrides to  particular  format  implementations,  or  additions  of  new  ones,  can  be  done  through
       "format_validations" in JSON::Schema::Modern.

       Format "uri-template" is not yet implemented.  Use of this format will always result in an error.
