                    Repeatable. Minimum of 13 and maximum of 236 octets
                    consisting of graphic characters. Colon ‘:’ is only allowed as
                    specified, the asterisk ‘*’ and question mark ‘?’ are not allowed,
                    nor are the octet values 42 and 63.

                    The character encoding used for this dataset must encode the
                    colon ':' using octet value 58, and must not use this octet value
                    for any other purpose.

                    The Subject Reference is a structured definition of the subject
                    matter. It must contain an IPR (default value is "IPTC"), an 8
                    digit Subject Reference Number and an optional Subject Name,
                    Subject Matter Name and Subject Detail Name. Each part of the
                    Subject reference is separated by a colon (:). The Subject
                    Reference Number contains three parts, a 2 digit Subject
                    Number, a 3 digit Subject Matter Number and a 3 digit Subject
                    Detail Number thus providing unique identification of the
                    object's subject.

                    If the Subject Matter or Subject Detail is not defined then a value
                    of 000 is used for the Subject Matter Number and/or Subject
                    Detail Number as appropriate. (See Appendices H and I).
                    The DataSet may be repeated when the objectdata content is
                    relevant to several subjects of news interest. It can be
                    independent of provider and for any media form. The provider
                    must either use the IPTC scheme or one that has been defined
                    and published by the provider.

                    The construction of the Subject Reference is as follows:

                        • Information Provider Reference (IPR)
                            A name, registered with the IPTC/NAA, identifying the
                            provider that provides an indicator of the SDR content.
                            The default value for the IPR is "IPTC" and is mandatory if
                            the Subject Reference exists in the IPTC coding
                            scheme as displayed in Appendices H - J.

                            Individual registered Information Providers may at their
                            discretion extend the Subject Reference lists. However, they
                            may only add to the subject matter and/or subject detail included
                            in the IPTC lists, and must identify this by using their registered
                            IPR.The IPTC Subject list may not be extended.

                        • Subject Reference Number
                            Provides a numeric code to indicate the Subject Name plus
                            optional Subject Matter and Subject Detail Names in the
                            language of the service. Subject Reference Numbers consist
                            of 8 octets in the range 01000000 to 17999999 and
                            represent a language independent international reference to
                            a Subject. A Subject is identified by its Reference Number
                            and corresponding Names taken from a standard lists given
                            in Appendix H,I &J.These lists are the English language
                            reference versions.

                        • Subject Name
                            The third part, if used, is a text representation of the Subject
                            Number (maximum 64 octets) consisting of graphic
                            characters plus spaces either in English, as defined in
                            Appendix H, or in the language of the service as indicated in
                            DataSet 2:135

                            The Subject identifies the general content of the objectdata
                            as determined by the provider.

                        • Subject Matter Name
                            The fourth part, if used, is a text representation of the
                            Subject Matter Number (maximum 64 octets) consisting of
                            graphic characters plus spaces either in English, as defined
                            in Appendix I, or in the language of the service as indicated
                            in DataSet 2:135

                            A Subject Matter further refines the Subject of a News
                            Object.

                        • Subject Detail Name
                            The fifth part, if used, is a text representation of the Subject
                            Detail Number (maximum 64 octets) consisting of graphic
                            characters plus spaces either in English, as defined in
                            Appendix J, or in the language of the service as indicated in
                            DataSet 2:135

                    A Subject Detail further refines the Subject Matter of a News
                    Object. A registry of Subject Reference Numbers, Subject
                    Matter Names and Subject Detail Names, descriptions (if
                    available) and their corresponding parent Subjects will be held
                    by the IPTC in different languages, with translations as supplied
                    by members. See Appendices I and J.
