Some properties are common to all variable
types. These properties are described in this section instead of
in each operation section in the reference.
Implicit properties
All service operations have the implicit
properties Name, Title, Description, and Type. The
list
and
map
variable
types are collections and have the Subtype property, which defines
the type of data that they contain.
Name
A
name that identifies the variable in the process data model. The
name must be a valid XML element name and therefore cannot contain
spaces or special characters. The name must be unique to the process.
Title
(Optional)
A name that identifies the variable if it is exposed in a user interface such
as Workspace. If no value is provided for Title, the value of the
Name property is used by default.
Description
A
brief explanation of the purpose or contents of the variable. The
description is useful for communicating the purpose of the variable
to other process developers.
Type
The
variable type, which coincides with the type of data that it stores.
For example, a
string
variable stores string data.
Subtype
(Collections)
The type of data that
list
and
map
variables
store.
General
Properties that specify whether the
variable is involved in storing data when the process is initiated
or is completed.
Required
Select
this option to specify that the data this variable stores must be
provided when the process is invoked. If this option is not selected,
providing the data when invoking the process is optional.
Input
Select
this option to specify that the variable is a parameter that data
is provided for when invoking the process. The variable stores the
data when the process is invoked. For example, if the purpose of
a process is to manipulate a PDF document, create a
document
variable
and select the In property.
Output
Select
this option to specify that the data the variable stores is provided
in the process results. The results are available to the client
that invoked the process when the process is complete.
Enduser UI items

Workspace users can interact with the data that variables store.
These properties are applicable to these variable types:
-
boolean

byte

date

date-time
-

this option to make the variable available as search criteria for
Workspace users.

data to users in Workspace.
