=head1 NAME

SBOM::CycloneDX::ExternalReference - External Reference

=head1 SYNOPSIS

    SBOM::CycloneDX::ExternalReference->new();


=head1 DESCRIPTION

L<SBOM::CycloneDX::ExternalReference> provide a way to
document systems, sites, and information that may be relevant but are not
included with the BOM. They may also establish specific relationships
within or external to the BOM.

=head2 METHODS

L<SBOM::CycloneDX::ExternalReference> inherits all methods from L<SBOM::CycloneDX::Base>
and implements the following new ones.

=over

=item SBOM::CycloneDX::ExternalReference->new( %PARAMS )

Properties:

=over

=item C<comment>, An optional comment describing the external reference

=item C<hashes>, The hashes of the external reference (if applicable).

=item C<type>, Specifies the type of external reference.

=item C<url>, The URI (URL or URN) to the external reference. External
references are URIs and therefore can accept any URL scheme including https
(RFC-7230 - L<https://www.ietf.org/rfc/rfc7230.txt>), mailto
(RFC-2368 - L<https://www.ietf.org/rfc/rfc2368.txt>), tel
(RFC-3966 - L<https://www.ietf.org/rfc/rfc3966.txt>), and dns
(RFC-4501 - L<https://www.ietf.org/rfc/rfc4501.txt>). External references may
also include formally registered URNs such as CycloneDX
BOM-Link (L<https://cyclonedx.org/capabilities/bomlink/>) to reference
CycloneDX BOMs or any object within a BOM. BOM-Link transforms applicable
external references into relationships that can be expressed in a BOM or
across BOMs.
