Leturn:epc:id:Scheme:C1.C2...Cn be a Pure Identity <strong>EPC</strong> URI, where theScheme field of both URIs is the same. The number of components (n) depends on thevalue of Scheme.First, any Pure Identity <strong>EPC</strong> URI component Ci is said to match the corresponding PureIdentity Pattern URI component Pi if: Pi is a NumericComponent, and Ci is equal to Pi; or Pi is a PaddedNumericComponent, and Ci is equal to Pi both in numeric valueas well as in length; or Pi is a GS3A3Component or ADIExtendedComponent or ADIComponent,and Ci is equal to Pi, character for character; or Pi is a CAGECodeOrDODAAC, and Ci is equal to Pi; or Pi is a StarComponent (and Ci is anything at all)Then the Pure Identity <strong>EPC</strong> URI is a member of the set denoted by the Pure IdentityPattern URI if and only if Ci matches Pi i n.9 Memory Organization of Gen 2 RFID <strong>Tag</strong>s9.1 Types of <strong>Tag</strong> <strong>Data</strong>RFID <strong>Tag</strong>s, particularly Gen 2 RFID <strong>Tag</strong>s, may carry data of three different kinds: Business <strong>Data</strong> Information that describes the physical object to which the tag isaffixed. This information includes the Electronic Product Code (<strong>EPC</strong>) that uniquelyidentifies the physical object, and may also include other data elements carried on thetag. This information is what business applications act upon, and so this data isCopyright ©2005- 2011 <strong>GS1</strong> AISBL, All Rights Reserved. Page 53 of 218
