modelid

Modelid is a generic term used to denote a unique identifier assigned to a model artifact within a software system. It functions as a stable reference to a model, enabling retrieval, management, and provenance tracking across development, validation, and deployment processes.

In machine learning and MLOps, a modelid typically identifies a trained model artifact or a specific version within a model registry or deployment platform. The modelid remains constant even as metadata such as performance metrics or deployment environment changes, and it is often exposed in APIs and metadata payloads to support versioning and rollback. Variants such as modelId and model_id are common in different systems, reflecting camelCase and snake_case naming conventions.

In data modeling, software modeling, and repository contexts, the modelid identifies a model artifact such as a data schema, an object model, or a catalog entry. It supports cataloging, version control, and cross-referencing between documentation, tests, and deployment definitions.

In APIs and storage systems, modelid is commonly used as a parameter or path component to fetch or reference a particular model. Filenames, database keys, or registry records may embed the modelid to ensure a durable linkage to the underlying artifact.

Representations vary by system: modelid may be a UUID, a numeric sequence, or an alphanumeric string. Naming conventions include modelId (camelCase), model_id (snake_case), or upper-case identifiers in certain schemas. Guidance emphasizes immutability after creation and strict validation of format and uniqueness.
