If theinput GS1 element string did not include an extension (AI 254), use a single zero digit(‘0’) as the entire serial number s 1 s 2 …s K in the EPC URI.Example (without extension):EPC URI: urn:epc:id:sgln:0614141.12345.0GS1 element string: (414) 0614141 12345 2Example (with extension):EPC URI: urn:epc:id:sgln:0614141.12345.32a%2FbGS1 element string: (414) 0614141 12345 2 (254) 32a/bSpaces have been added to the GS1 element string for clarity, but they are never encoded.In this example, the slash (/) character in the serial number must be represented as anescape triplet in the EPC URI.7.4 Global Returnable Asset Identifier (GRAI)The GRAI EPC (Section 6.3.4) corresponds directly to a serialized GRAI key defined inSections 2.3.1 and 3.9.3 of the GS1 General Specifications [GS1GS10.0]. Because anEPC always identifies a specific physical object, only GRAI keys that include theoptional serial number have a corresponding GRAI EPC. GRAI keys that lack a serialnumber refer to asset classes rather than specific assets, and therefore do not have acorresponding EPC (just as a GTIN key without a serial number does not have acorresponding EPC).EPCURIurn:epc:id:grai:CompanyPrefixAssetTypeSerial1372137313741375137613771378GS1ElementString(8003) 0CompanyPrefixAssetTypeCheckDigitSerialFigure 11.Correspondence between GRAI EPC URI and GS1 Element StringNote that the GS1 Element String includes an extra zero (‘0’) digit following theApplication Identifier (8003). This zero digit is extra padding in the element string,and is not part of the GRAI key itself.Formally, the correspondence is defined as follows. Let the EPC URI and the GS1element string be written as follows:Copyright ©2005- 2011 GS1 AISBL, All Rights Reserved. Page 46 of 218
