This document specifies requirements for using identifiers in distributed ledgers including blockchains. These requirements supplement those of ISO 8000-115.The following are within the scope of this document:— requirements for each identifier in distributed ledgers including blockchains, where the ledger enables supply chains to exchange transaction data;— requirements for the off-ledger data set that is referenced by an identifier in a distributed ledger;— off-ledger data sets that consist only of property-value tuples, where each tuple is the result of semantic encoding.The following are outside the scope of this document:— requirements for implementing distributed ledger technology including blockchains;— requirements for technology to ensure immutability of data sets;— requirements for the processes of creating identifiers;— requirements for the processes of creating the content of off-ledger data sets;— requirements for the processes of creating immutable data sets.
