Schema design
A schema is a graphical data dictionary that contains metadata definitions of the structure of a document to generate test data. Schema provides visual cues for understanding the structure and complete definition of an object.
Type properties
The properties of a type define the characteristics of the data objects of that type.
Group properties
Implicit format
Floating component

- Files
  You add a file to a project to use it as input in the project. You can upload a file from your local file system to a project from the Files tab to generate test data. Alternatively, you can upload it when you define an action.
- Connections
  A connection defines the properties that are required to connect to an external resource. An action uses a connection to provide source data to a project or write data from a source to a target. Multiple actions can use the same connection. You can define both connections and actions at the project level.
- Schema design
  A schema is a graphical data dictionary that contains metadata definitions of the structure of a document to generate test data. Schema provides visual cues for understanding the structure and complete definition of an object.
  - Introduction to schema design
    Use the Schemas tab to define, modify, and view schemas. A schema describes the syntax, structure, and semantics of your data.
  - Type properties
    The properties of a type define the characteristics of the data objects of that type.
    - Defining type properties
    - Basic type properties
    - Item properties
    - Group properties
      - Group subclass
      - Sequence group formats
      - Explicit format
      - Implicit format
        Floating component
        Implicit whitespace syntax
        Implicit delimited syntax
        No syntax
        Distinguishable components of an implicit group
      - Specifying a delimiter
      - Defining exclude characters
        During the 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.
    - XML properties in the schema
  - Item restrictions
    Item restrictions are an optional feature you can use to specify valid or invalid data objects for an item type. Item restrictions are grouped into three categories: Value, Character, and Range.
  - Components
  - Partitioning
  - Type inheritance
  - Schema analyzer
  - Distinguishable objects
  - Functions and expressions

Floating component

The floating component represents an object that may appear after any component of the group.

An implicit group can have a floating component; an explicit group cannot. If the group is prefix or infix delimited, the floating component is displayed before the delimiter. If the group is postfix delimited, the floating component is displayed after the delimiter.

A floating component can be an optional component that may appear after any other component. However, it is not included in the component list because it does not appear at a specific location.

If a group has a floating component, a component must be distinguishable from a floating component. For example, components and floating component could start with different initiators.

Note: When a floating component appears in the input data, it is validated during mapping. If there are floating components in your output data, define them as actual components of the output.

A floating component can appear after the initiator (when the type has an initiator), after each component, or both. For EDI and other existing floating components, trees will be converted as after each component.

A floating component can be specified for implicit sequence group, choice group, and unordered group definitions.
