9.1.1 Identification and compatibility of EI types
An EI type is identified by a EiTypeId as defined in A1AP [3]. The EiTypeId is a string that consists of two parts: a typename and a version. When updating an EI type, the version in the EiTypeId is updated according to SemVer [19] to reflect its compatibility with other EI types that has the same typename. Two EI type...

9.1.2.1 EI job status
This is a generic EI job status schema, it may be adjusted and used together with an EI job schema in an EiTypeObject and will then be identified by the same EI type identifier as the EI job schema. { "$schema": "https://json-schema.org/draft/2020-12/schema", "description": "O-RAN standard EI status", "type": "object",...

9.1.2.2 Scope identifiers and common data types
The EI job definition schemas defined in clause 9.2 can be base schemas that embed a subschema with common data types definitions in same way as described for policy types in clause 7.1. An EI type definition can link to the common data types schema defined in clause 7.1.2.1 and the compatibility relations are the same...

9.1.2.3 Schema identification
The EI type identifier is part of the $id keyword included in the EI job definition schema. The $id keyword for the EI job definition schemas are constructed from the URI base and the EI type identifier in the same was as for policy types as described in clause 7.1.3.2. The base URI for EI types is the same as for poli...
