Tags applied to API operations help organize and group paths, methods, and operations in documentation, but also shape the bounded context of APIs for generating SDKs, sandboxes, testing, security, and other areas of API operations. The words and phrases used at the operational level should fit into the larger API vocabulary of the domain, line of business, and teams producing APIs.
The tags that teams apply to individual operations should reflect the path segments, methods, and operation summaries applied to each operation, and be part of a larger API design strategy and enterprise API vocabulary. The operation tags should be deliberate and natural, and used at a tactical level, but reflect wider strategic planning. Tags are how you organize and discover your API resources and capabilities across the enterprise.
