- 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.

- Files
  Files are used in various places within HCL Link. HCL Link allows files to be uploaded to the HCL Linkserver.

Element and attribute wildcards

DTDs and XML Schemas allow the specification of wildcard elements within a grammar. The XML Schema and DTD importers recognize element wildcards, build the appropriate types, and set the appropriate properties for those types to represent element wildcards in the schema.

During the import process, when a wildcard element resolves to an element that is not defined in the imported grammar, it is represented by a text item.

The value of these text items is the text string from the input buffer that runs from the start of the open tag to the end of the close tag for that element.

XML Schemas allow the specification of an attribute wildcard that matches any number of undeclared attributes within the element tag. The XML Schema Importer recognizes the attribute wildcard and creates a sequence of name and value text item pairs within the attribute list of the enclosing element. The XML validation library fills this sequence with the names and values of attributes that do not match any declared attributes in the attribute list.
