Use the schema designer to define, modify, and view schemas. A schema describes the syntax, structure, and semantics of your data.

- Flows
  This documentation describes how Flows can be run from REST API, listeners, or they can be scheduled.
- Maps
  Maps define input and output specifications and mapping rules for data transformation.
- Schemas
  Use the schema designer to define, modify, and view schemas. A schema describes the syntax, structure, and semantics of your data.
  - About schemas
    A schema defines the contents of at least one input that you intend to map or one output you intend to map.
  - Subtypes
  - Schema hierarchy
  - Defining data
  - Objects, types, and classes
  - Testing part of a schema
    You can test a schema by generating test data for an item or a group. The schema designer creates source and compiled maps that generate and validate the test data. The test-data-generation map automatically runs and produces a text file with the sample data. After that, the test-data-validation map automatically runs on the sample data file.

  - Item restrictions
  - Components
  - Partitioning

  - Native XML schema support
    HCL Link provides Native XML schema support.
  - Native JSON schema support
    This documentation describes the Native JSON schema support.
    - Importing JSON documents
      A JSON document can be used to define a schema. This process is known as importing a JSON document. Schemas defined in this way are called native JSON schemas.
    - The representation of JSON types in Link schemas
      A JSON object is represented as a group type in a native JSON schema. The components of the group type correspond to the properties of the JSON object. The name of a component, which is the name of the type of the component, corresponds to the name of the property of the JSON object.
    - Using native JSON schemas in a map
      A native JSON schema can be used in an input card or an output card.
      - JSON cards and text encoding
        When an input card uses a native JSON schema, the text encoding of input data is determined automatically during map execution.

- Connections and Actions
  This documentation describes connections and actions.
- Files
  Files are used in various places within HCL Link. HCL Link allows files to be uploaded to the HCL Linkserver.

Using native JSON schemas in a map

A native JSON schema can be used in an input card or an output card.

Unlike regular schemas, a specific type within a native JSON schema may not be selected for a card. The group type beneath the root category type is selected automatically for the card.
