This subsection is required in every IDMPO, but is onlyrequired in an IDLPO that uses the non-default format supporting multiple ID Lists.An Application Indicator consists of the following components:A single AppIndicatorPresent bit, which if ‘0’ means that no additional ID List orMap follows. Note that this bit is always omitted for the first List or Map in anObject Info section. When this bit is present and ‘0’, then none of the following bitfields are encoded.A single ExternalReg bit that, if ‘1’, indicates use of an ID Table from a registrationother than the memory’s default. If ‘1’, this bit is immediately followed by a 9-bitrepresentation of a Data Format registered under ISO/IEC 15961.An ID Size pattern which denotes a table size (and therefore an ID Map bit length,when used in an IDMPO), which shall be one of the patterns defined by Table I 5-5.The table size indicated in this field must be less than or equal to the table sizeindicated in the selected ID table. The purpose of this field is so that the decoder canparse past the ID List or ID Map, even if the ID Table is not available to the decoder.a three-bit ID Subset pattern. The registered data format’s Primary Base ID Table, ifused by the current Packed Object, shall always be indicated by an encoded ID Subsetpattern of ‘000’. However, up to seven Alternate Base Tables may also be defined inthe registration (with varying ID Sizes), and a choice from among these can beindicated by the encoded Subset pattern. This feature can be useful to define smallerCopyright ©2005- 2011 GS1 AISBL, All Rights Reserved. Page 174 of 218
