Transform a Qlerify Event Modeling JSON export into EventCatalog-compatible MDX artifacts with JSON Schema.

This command loads all relevant preferences for: Qlerify to EventCatalog transformation workflow, EventCatalog tooling (schema documentation), json querying (duckdb, jaq), functional domain modeling (DDD aggregates, Decider pattern), and schema versioning.

Prerequisites

•Qlerify JSON export file from Event Modeling session
•Target EventCatalog project directory (or will create structure)

Workflow

Phase 1: Export Discovery

If $ARGUMENTS provided, use that as the JSON export path. Otherwise, ask user to provide the path to the Qlerify JSON export.

Use discovery queries to understand export structure:

bash

jaq 'keys' export.json
jaq '[.domainEvents[].cards[].cardType.domainModelRole] | group_by(.) | map({role: .[0], count: length})' export.json
jaq '.lanes | map(.name)' export.json

Phase 2: Structure Analysis

Analyze with duckdb for relationships:

•Count entities by type (Command, Query, Entity)
•Analyze event flow depth (parent chains)
•Check lane distribution (events per service)
•Identify schema field complexity

Phase 3: EventCatalog Generation

Generate MDX artifacts for each domain element:

Events (from domainEvents with orange cards):

code

/events/[EventName]/index.mdx
/events/[EventName]/schema.json

Commands (from Command role cards):

code

/commands/[CommandName]/index.mdx
/commands/[CommandName]/schema.json

Queries (from ReadModel role cards):

code

/queries/[QueryName]/index.mdx
/queries/[QueryName]/schema.json

Services (from lanes/bounded contexts):

code

/services/[ServiceName]/index.mdx

Flows (from event parent relationships):

code

/flows/[FlowName]/index.mdx

Phase 4: Schema Generation

For each entity with fields, generate JSON Schema:

•Map Qlerify data types to JSON Schema types
•Include required fields based on primaryKey
•Add relationship references via $ref
•Include enum values from exampleData

Phase 5: Validation

Verify generated artifacts:

•All events have corresponding MDX files
•All commands reference valid events
•All schemas are valid JSON Schema
•Flow steps maintain temporal ordering
