Schemas tell Darpan how to parse and compare source files or records. A schema turns a source shape into stable fields that a run can reuse.
When to create a schema
Create a schema when a workflow needs to parse a new file shape, compare a new record shape, or preserve a reusable data contract for repeated runs.
Steps
- From Ask Darpan, open Create Schema.
- Provide the schema name or identifier.
- Select the source system when the workflow asks for it.
- Add or confirm the fields Darpan reads.
- Review field names, data types, and required markers.
- Save the schema.
Existing schemas are available from Open Schema Library.
Review checklist
- Field names match the source system or agreed normalized names.
- Required fields are marked intentionally.
- Numeric, date, and identifier fields use stable types.
- The schema name is specific enough to understand in saved run history.
Prefer one clear schema per source shape over reusing a vague schema that needs manual interpretation every time.
