This column entry, if present, may contain one or more of the following keywordassignments (separated by semicolons), as were previously defined (see J.1.1 and J.1.2): K-RootOID = urn:oid:i.j.k.l… K-Interpretation = string K-ISO15434=nnIf used, these override (for a particular Identifier) the default file-level values and/orthose specified in the Table Header section.J.3 Syntax of OIDs, IDstring, and FormatString ColumnsIn a given ID Table entry, the OIDs, IDString, and FormatString column may indicateone or more mechanisms described in this section. J.3.1 specifies the semantics of themechanisms, and J.3.2 specifies the formal grammar for the ID Table columns.J.3.1 Semantics for OIDs, IDString, and FormatString ColumnsIn the descriptions below, the word “Identifier” means either an OID final arc (in thecontext of the OIDs column) or an IDString name (in the context of the IDstring column).If both columns are present, only the OIDs column actually invokes Secondary ID bits. A Single component resolving to a single Identifier, in which case no additionalSecondary ID bits are invoked. (For OIDs and IDString columns only) A single component resolving to one of aseries of closely-related Identifiers, where the Identifier’s string representation variesonly at one or more character positions. This is indicated using the Concatenationoperator ‘%’ to introduce a range of ASCII characters at a specified position. Forexample, an OID whose final arc is defined as “391n”, where the fourth digit ‘n’ canbe any digit from ‘0’ to ‘6’ (ASCII characters 30 hex to 36 hex inclusive) is representedby the component 391%x30-36 (note that no spaces are allowed) A Concatenationinvokes the minimum number of Secondary ID digits needed to indicate the specifiedrange. When both an OIDs column and an IDstring column are populated for a givenrow, both shall contain the same number of concatations, with the same ranges (sothat the numbers and values of Secondary ID bits invoked are consistent). However,the minimum value listed for the two ranges can differ, so that (for example) theOID’s digit can range from 0 to 3, while the corresponding IDstring character canrange from “B” to “E” if so desired. Note that the use of Concatenation inherentlyconstrains the relationship between OID and IDString, and so Concatenation may notbe useable under all circumstances (the Selection operation described below usuallyprovides an alternative). A Combination of two or more identifier components in an ordered sequence,indicated by surrounding each component of the sequence with parentheses. Forexample, an IDstring entry (A)(%x30-37B)(2C) indicates that the associated IDValue represents a sequence of the following three identifiers: Identifier “A”, thenCopyright ©2005- 2011 GS1 AISBL, All Rights Reserved.
