We call\nthis entity an **API resource**. API resources stored in API hub are searchable and provide detailed\noperational and descriptive information about the API.\n\nAn API resource is a complex entity that can have one or more versions associated with it.\nYou can think of a version as the state of an API at a point in time. Each version can have\nits own set of entities such as [operations parsed from an API specification](./specs-intro#specificationparsing), [deployments](/apigee/docs/apihub/deployments-intro),\nand [API specifications](/apigee/docs/apihub/specs-intro), as shown in Figure 1.\n\n**Figure 1.** An API can have multiple versions.\n\nEither at the time you register an API or afterwards,\nyou can add and edit API resource attributes to build\na rich description of the API. See [Manage attributes](./manage-attributes).\n\nAPI hub supports both system-defined and user-defined attributes. Examples of system defined attributes include:\n\n- **API style**: An attribute with default values of REST, gRPC, SOAP, and Async API.\n- **Target users**: The intended users (consumers) of an API\n- **Team**: The producing team or teams responsible for an API\n- **Business unit**: The business unit responsible for an API\n- **Maturity level**: An indication of the API's lifecycle stage\n\nFinally, an API resource can have [user-defined attributes](./manage-attributes#user-attributes), which you define in Settings based on your\norganizational or team needs."]]
