Design Server
The documentation provided here describes how to use the Design Server.
- Projects
  This documentation describes Design Server projects.
- Schemas
- Maps
- Flows
  A flow node invokes a sub flow within a flow. Sub-flows need not be wired to other nodes; it is valid to have a flow that is comprised of multiple sub-flows that each have listeners.
- Using Design Server
  How to use the HCL Link Design Server.
- Flows
  This documentation describes how Flows can be run from REST API, listeners, or they can be scheduled.
- Schema designer
  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.

      - Implicit format
      - Specifying a delimiter
      - Defining exclude characters
        During map run time, the data validation process uses the Exclude Character List group property to define a set of characters that are not allowed to exist in the data stream as data content.
      - Escaping an excluded character in the data content
        Select Release exclude characters when you configure the exclude character list to enable the release character to escape excluded characters. When enabled, a release character that precedes an excluded character in data content escapes the excluded character, and the data content passes validation. Likewise, Link precedes an excluded character with the release character when building the output stream.

Explicit format

To specify that a group has an explicit format, choose Explicit for the Format property. Select a setting for the Track property, and choose the group's syntax: Fixed or Delimited.
