In certain bar code applications, this is accomplished through theuse of leading zeros. If 96-bit tags are used, however, the option to use leading zerosdoes not exist.Therefore, in applications that both require 96-bit tags and require that the serial numberbe a fixed number of characters, it is recommended that numeric serial numbers be usedthat are in the range 10 D D+1 , where D is the desired number of digits. Forexample, if 11-digit serial numbers are desired, an application can use serial numbers inthe range 10,000,000,000 through 99,999,999,999. Such applications must take care touse serial numbers that fit within the constraints of 96-bit tags. For example, if 12-digitserial numbers are desired for SGTIN-96 encodings, then the serial numbers must be inthe range 100,000,000,000 through 274,877,906,943.It should be remembered, however, that many applications do not require a fixed numberof characters in the serial number, and so all serial numbers from 0 through themaximum value (without leading zeros) may be used with 96-bit tags.12.3.2 EPC Pure Identity URI to EPC Tag URIGiven: An EPC Pure Identity URI as specified in Section 6. This is a string that matches theEPC-URI production of the grammar in Section 6.3. A selection of a binary coding scheme to use. This is one of the the binary codingschemes specified in the “EPC Binary Coding Scheme” column of Table 15. Thechosen binary coding scheme must be one that corresponds to the EPC scheme in theEPC Pure Identity URI. A filter value, if the “Includes Filter Value” column of Table 15 indicates that thebinary encoding includes a filter value. The value of the attribute bits. The value of the user memory indicator.Validation: The serial number portion of the EPC (the characters following the rightmost dotcharacter) must conform to any restrictions implied by the selected binary codingscheme, as specified by the “Serial Number Limitation” column of Table 15. filter Procedure:1. Starting with the EPC Pure Identity URI, replace the prefix urn:epc:id: withurn:epc:tag:.2. Replace the EPC scheme name with the selected EPC binary coding scheme name.For example, replace sgtin with sgtin-96 or sgtin-198.3. If the selected binary coding scheme includes a filter value, insert the filter value as asingle decimal digit following the rightmost colon (“:”) character of the URI,followed by a dot (“.”) character.Copyright ©2005- 2011 GS1 AISBL, All Rights Reserved.
