Workflow State Schema

A Workflow State Schema is a data schema that defines the structure and constraints for workflow execution state representation in workflow management systems.

• AKA: Workflow State Model, Workflow Data Schema, Process State Schema, Workflow State Definition.
• Context:
  • It can typically define Workflow State Attributes through workflow state field definitions with workflow state data types.
  • It can typically specify Workflow State Constraints through workflow state validation rules with workflow state integrity checks.
  • It can typically model Workflow State Relationships through workflow state references with workflow state foreign keys.
  • It can typically support Workflow State Versioning through workflow state version tags with workflow state migration paths.
  • It can often enable Workflow State Serialization through workflow state JSON formats with workflow state encoding rules.
  • It can often facilitate Workflow State Querying through workflow state indexes with workflow state access patterns.
  • It can often provide Workflow State Validation through workflow state schema validators with workflow state type checkers.
  • It can often ensure Workflow State Consistency through workflow state invariants with workflow state transaction boundarys.
  • It can range from being a Simple Workflow State Schema to being a Complex Workflow State Schema, depending on its attribute count.
  • It can range from being a Flat Workflow State Schema to being a Nested Workflow State Schema, depending on its structure depth.
  • It can range from being a Static Workflow State Schema to being a Dynamic Workflow State Schema, depending on its runtime flexibility.
  • It can range from being a Strongly-Typed Workflow State Schema to being a Loosely-Typed Workflow State Schema, depending on its type strictness.
  • It can range from being a Minimal Workflow State Schema to being a Comprehensive Workflow State Schema, depending on its state coverage.

• Example(s):
  • JSON Workflow State Schemas, such as:
    • OpenAPI Workflow State Schema for REST API workflow state.
    • GraphQL Workflow State Schema for GraphQL workflow mutation.
    • JSON Schema Draft Workflow State for standard JSON validation.
  • Database Workflow State Schemas, such as:
    • PostgreSQL Workflow State Table Schema for relational workflow storage.
    • MongoDB Workflow State Document Schema for NoSQL workflow persistence.
    • Redis Workflow State Key Schema for in-memory workflow cache.
  • Framework-Specific Workflow State Schemas, such as:
    • Temporal Workflow State Schema for durable workflow execution.
    • Apache Airflow DAG State Schema for data pipeline state.
    • Camunda Process State Schema for BPMN workflow instance.
  • Protocol Buffer Workflow State Schemas, such as:
    • gRPC Workflow State Message Schema for service communication.
    • Protobuf Workflow Event Schema for event streaming.
  • ...
• Counter-Example(s):
  • Workflow Definition Schema, which defines workflow structure rather than runtime state.
  • Workflow Configuration Schema, which specifies static settings rather than dynamic state.
  • Unstructured Workflow Data, which lacks formal schema and type definition.
