Projects
A project is a container for HCL Link artifacts.
- 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.
  - Using Maps
  - Create maps to specify sources and targets
  - Maps and map source files
    Basic tasks involved in creating and managing maps.
  - Input and output cards
  - Card settings
  - Map rules
  - Formulating map rules
    - When input data is missing
      - When portions of an input series are missing
      - When an output evaluates to NONE
    - Mapping an input item to an output item
    - Mapping a group to a group
    - Outputs with maximum range greater than 1
    - Indexing an output
      When you know the number of objects to generate for each map execution, index the number of occurrences of that output object. To index an output is to generate a specific number of occurrences of that output.
    - Mapping to multiple occurrences of a group
    - Indexing an Input

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

When input data is missing

If you map an input to an output, but the input is missing, either the output will have no content or it will not exist. The existence of the output depends on how the output is defined.
