This document supports supply chain interoperability and integration and provides the fundamental structure for exchanging verified data in an industrial internet. Identifiers, like part numbers, are the shorthand for datasets throughout the supply chain. This document provides methods to verify identifiers and datasets behind identifiers used in the supply chain, specifically the format of and automated request types (verify, resolve, and search) and replies to those requests. The following are within the scope of this document:

• the syntax requirements and application protocol interface (API) for a request and response to a request for the verification of identifiers formatted in accordance with ISO 8000-115 (verify);
• the syntax requirements and API for a request and response to a request for a dataset of an identifier formatted in accordance with ISO 8000-115 (resolve);
• the syntax requirements and API for a request and response to a request to search for an identifier formatted in accordance with ISO 8000-115 given characteristic data (search).

The following are outside the scope of this document:

• the methods used for the resolution of identifiers by the identifier issuer;
• the data elements required for resolution of identifiers.
