portaljs-define-schema

separate

Define a dataset's metadata profile — infer a Frictionless Table Schema from its data, add Data Package metadata (license, sources, keywords), and write it into datasets.json so the showcase renders a typed field table. Extend or customize via the L0-L3 profile ladder. Use when a registered dataset needs field types, constraints, or catalog metadata before publishing.

When to use

• infer Frictionless Table Schema
• add Data Package metadata
• write schema to datasets.json
• customize L0-L3 profiles
• define field types and constraints
• catalog metadata for registered datasets

When not to use

• registering new datasets
• scaffolding new portals
• authoring DCAT serialization
• processing non-tabular data for fields
