Creating a unit definition

To create a unit definition:

  1. Do either of the following:
    • Select File > New > Unit.
    • In the Trial Objects window, right-click the Units node. From the pop-up menu, choose Add Unit.

    The Unit window opens in the Trial Design workspace. This window consists of the MedML tab, which displays the MedML tags that define the unit.

  2. Create a conversion rule to convert the entered value to the base value. For examples, see Example of conversion rule for Inches unit and Example of conversion rule for Centimeter unit.
  3. In the Properties window, enter values for the properties described in the following table:

    Property

    UUID

    String that uniquely identifies the component across all databases, trials, and machines.

    Note that the InForm Architect application automatically capitalizes UUID strings that contain lower-case characters.

    OPTIONAL. Note that the unit definitions that are installed with the Base trial include predefined UUID properties. These UUIDs are not currently used. They are provided for possible future use and are listed for reference in UUIDs.
