Policy Labels UI

Last updated
Access to Policy Labels functionality is controlled by the corresponding permissions settings.
Users can review the list of existing labels and their statuses in the corresponding section of Guardian UI.
A new Policy Label definition can be created by clicking on the ‘Create New’ button on the Policy Labels page.
After the initial creation, Policy Label definitions must be configured further to be usable.
Generic configuration of Policy Label definitions consists of name and description field. Label authors should configure meaningful names and descriptions for their labels as these are the attributes label users would rely on to understand the applicability of labels to their specific use-cases.
To include other published label definitions and statistics into the definition of a label being configured, these structural components must be imported into the context of the current label. Import operation links a parent label with the imported elements, which makes them available to the Label author in the side menu of the UI.
Label configurator consists of 3 sections
1. Side menu, for displaying components which can be dragged-and-dropped into the label editor.
2. Label editor, which hosts the components where they can be arranged into a hierarchical structure representing the evaluation logic.
3. Component properties, which define specifics of the behavior of the individual components.
2.3.3.1 Components: Groups
Groups are components which define the general structure of Labels. Each group has its own name (title) in the navigation panel and represents a specific namespace in which components have access to each other's variables. Groups define sufficient validity conditions for the target documents.
Configuration
Tag – the name of the namespace
Title – title in the navigation panel
Rule – defines the principle by which the group will be evaluated
At least one – the group is considered valid if at least 1 of the direct (immediate) child components is valid
Every – the group is considered valid if all direct (immediate) child components are valid
2.3.3.2 Components: Rules
Rules are defined in terms of variables, scores, formulas and conditions.
A Rule is considered ‘valid’ if all its conditions successfully verify for the set of provided data.
Configuration
Tag – name of the namespace
Title – title in the navigation panel
For components which are members of the same group, each component that is positioned below another component (i.e. ‘follows’ the prior component) has access to the variables of the previous component via its Tag.
2.3.3.2.1 Editing Rules
Rules can be edited in the corresponding area of the UI:
Rules editor consists of 2 sections:
1. Schema hierarchy and content (fields) display, which allows users to find and select specific fields in schemas for use in the Label calculation/evaluation (see more detailed description in the Statistics documentation section) .
2. Formula and Rules configurator (see more detailed description in the Statistics and Schema Rules documentation sections).
2.3.3.3 Components: Statistics
Existing Statistics can be used as components in Labels. As they don’t contain conditions they are always evaluated as valid when the Label which contains them is evaluated. Therefore, their primary function is to serve as data sources for other components in the Label, as their variables can be accessed directly by other components in the same namespace.
2.3.3.4 Components: Labels
Existing labels can be used as components of other (higher order) labels. The internal structure of such embedded labels remains unchanged.
2.3.4 Saving
It is recommended to frequently use ‘Save’ button to preserve the current state of the Label being edited.
2.3.5 Preview
Label authors can preview (i.e. ‘dry run’ test) their Label functioning once its definition is complete by clicking the ‘Preview’ button in the configurator UI. Such test evaluations require manual input of the test data.
Components which were successfully validated on the provided test data would be marked in green, the unsuccessful results are marked in red.
2.3.6 Publishing
To enable other users to find and use the Label it must be published.
Once the Label has been published it can be used to create Label documents on specific token data.
2.4.1 Targets
The first step in the creation of a Label document is to select the target token (i.e. a VP document linked to the token).
2.4.2 Label evaluation
All steps defined in the Label evaluation flow must be followed.
2.4.3 Results
If a Label is evaluated as valid a corresponding document is created containing all Label information. This document can be published to make it accessible externally.
Existing Label documents can be accessed from the corresponding grid.
