Resource Flow Properties

You can modify an object's properties from its property sheet. To open a resource flow property sheet, double-click its diagram symbol or its Browser entry in the Resource Flows folder.

The General tab contains the following properties:

Property	Description
Name	Specifies the name of the item, which should be clear and meaningful, and should convey the item's purpose to non-technical users.
Code	Specifies the technical name of the object, which is used for generating code or scripts.
Comment	Specifies a descriptive comment for the object.
Process / Resource	Specifies the extremities of the resource flow. Use the tools to the right of the list to create, browse for, or view the properties of the currently selected object.
Stereotype	Extends the semantics of the object. You can enter a stereotype directly in this field, or add stereotypes to the list by specifying them in an extension file.
Message format	[Not available for BPMN and DFD languages]. Specifies the format of the data exchanged between the process and the resource. You can choose from the following values: None – no exchange of data. Undefined [default] – Click the Create tool to the right of the list to create a message format (see Message Formats (BPM)).
Access mode	Specifies the way to access data in a resource, and thus defines the resource flow direction. You can choose from the following values: Read – from resource to process. Create, Update, Delete – from process to resource.

Condition Tab

The Condition tab defines the nature of the condition attached to a resource flow, and contains the following properties:

Parameter	Description
Alias	Short name for the condition to be displayed next to its symbol in the diagram.
Condition (text box)	Specifies a condition to be evaluated to determine how the resource flow should be traversed. You can enter any appropriate information in this box, as well as open, insert and save text files. You can open the Condition tab by right-clicking the resource flow symbol, and selecting Condition in the contextual menu. The condition is displayed next to the process symbol:

When there are several flows, each condition is evaluated in order to choose the one the resource flow will transit on.

Data Tab

This tab is only available for the Analysis and the Data Flow Diagram languages and lists the data associated with the resource flow. You can add or create data, and specify which data is conveyed by the resource flow without any information on its format (see Specifying Data for a Flow, a Resource Flow or a Message Format).
