Design of the FRAMES Domain Editor

FRAMES 2.0 allows the user to conduct a risk analysis using modules categorized by classes (models, viewers, databases, and systems). Domains organize these modules in a particular way (a palette) for a particular analysis. Within a domain, a module can be categorized under a group or subgroup within a class. The domain icon can be modified, but none of the classes can be added or deleted from the domain. There can be multiple instances of a module in a domain.

In previous versions of FRAMES, only one domain existed, and groups were static. With FRAMES 2.0, multiple domains can be created with any combination of groups and subgroups. The Domain Editor allows the user to set up a palette by adding, deleting, and changing icons. The following sections describe the design that allows users to manage the palette through domains, groups, and subgroups.

Managing Domains

The FRAMES analysis starts with a domain. Each analysis requires at least one domain. To create a domain, the user must add a domain in the Domain Editor by selecting the root (top) node called "Domains." A list of domains will appear in the panel on the right-hand side. The user clicks the "Add Domain" button. When the input box appears, the user enters a name for the new domain. On confirmation, the Domain Editor adds a new domain along with the four base classes.

Once a domain has been added, the user can manipulate it in several ways, such as deleting it, editing its icon to distinguish it from another domain, or editing the icon belonging to a class to show a more narrow analysis. To delete a domain, the user selects the root (top) node and highlights a domain from the available list. The user then clicks on the "Delete Domain" button. On confirmation, the Domain Editor removes the domain and classes from the available list.

To edit a domain's icon, the user selects a domain and clicks on the "Edit Domain Icon" button. On the Open File form, the user locates and opens an icon. The Domain Editor modifies the icon to the one selected.

To edit a class's icon, the user selects a class under a domain and clicks on the "Edit Class Icon" button. On the Open File form, the user locates and opens an icon. The Domain Editor modifies the icon to the one selected.

Managing Groups

A group may contain multiple subgroups, modules, and an icon to be displayed in FRAMES 2.0. Groups and subgroups are the only locations where a module can be added to a domain. Groups can be managed by adding a group, deleting a group, editing a group's icon, adding a module to a group, and deleting a module from a group.

To add a group to the domain, the user selects a class under the domain on the user interface and clicks the "Add Group" button. In the input box, the user then enters a name for the new group. On confirmation, the Domain Editor adds a new group.

To delete a group from the domain, the user selects a class under the domain, then highlights the group from the available list. The user clicks on the "Delete Group" button. On confirmation, the Domain Editor removes the group from the list.

To edit a group's icon, the user selects a group and click's on the "Edit Group Icon" button. In the Open File form, the user then locates and opens an icon. The Domain Editor modifies the icon.

To add a module to a group, the user selects a group and clicks on the "Add Module" button. The user then locates a module from the list and clicks on the "Add Module" button again. The Domain Editor adds the module to the available list. Only modules belonging to a specific class are available to be added. A module's class and the domain's class in which the group or subgroup resides must match in order to add the module.

Note that when a module is added to a group or subgroup, the user may not modify the icon to be displayed on the FRAMES' palette. If the module has an icon associated with it, that icon will be displayed. However, if a module does not specify an icon, then an icon will automatically be determined from the group or subgroup to which the module belongs.

To delete a module from a group, the user selects a group and then highlights a module from the available list. On confirmation, the Domain Editor will remove the module from the list.

Managing Subgroups

A subgroup may also contain multiple modules and an icon that will be displayed in FRAMES 2.0. Any module that does not declare an icon when it was added to the system will inherit the subgroup's icon. Subgroups may be managed by adding a subgroup, deleting a subgroup, editing a subgroup's icon, adding a module to a subgroup, and deleting a module from a subgroup.

To add a subgroup to a domain, the user selects a group in the user interface and clicks on the "Add Subgroup" button. On the input box, the user then enters a name for the new subgroup. On confirmation, the Domain Editor adds the new subgroup.

To delete a subgroup, the user selects a group and highlights a subgroup from the available list. The user then clicks on the "Delete Subgroup" button. On confirmation, the Domain Editor deletes the subgroup.

To edit a subgroup's icon, the user selects the subgroup and clicks on the "Edit Subgroup Icon" button. On the Open File form, the user locates and opens an icon. The Domain Editor modifies the subgroup's icon.

To add a module to a subgroup, the user selects a subgroup and clicks on the "Add Module" button. On the list of modules, the user then locates a module and clicks on the "Add Module" button again. Only modules belonging to a specific class are available to be added. A module's class and the class in which the subgroup resides must match in order to add the module. The Domain Editor then adds the module to the subgroup.

Note that when a module is added to a subgroup, the user may not modify the icon to be displayed on the FRAMES' palette. If the module has an icon associated with it, that icon will be displayed. However, if a module does not specify an icon, then an icon will automatically be determined from the group or subgroup to which the module belongs.

To delete a module from a subgroup, the user selects a subgroup and highlights a module from the available list. The user then clicks on the "Delete Module" button. On confirmation, the Domain Editor removes the module from the list.
