Leturn:epc:tag:EncName:C1.C2...Cn be an EPC Tag URI, where the EncNamefield of both URIs is the same. The number of components (n) depends on the value ofEncName.First, any EPC Tag URI component Ci is said to match the corresponding EPC TagPattern 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; orCopyright ©2005- 2011 GS1 AISBL, All Rights Reserved.
