InRule® includes a Standard Template Catalog that allows for Business Language entry of conditions, expressions, and actions. Rules may be entered “Topic First” (starting with the current context) or “Template First” — picking a template then filling it out.
Available templates are displayed based on context as a rule is authored. The user is prompted to define necessary fields or tokens, and is presented with a menu of appropriate choices.
The following categories contain all function templates for authoring expressions in Language Rules.
- Collection Templates - Operate across collection items to return aggregate values.
- Comparison Templates - Return values based on logical comparisons.
- Conditional Templates - Return values based on logical operations.
- Conversion Templates - Perform data type conversions.
- Date Templates - Perform date parsing and math operations.
- Math Templates - Perform arithmetic operations.
- Time-Value Templates - Perform time-value financial operations.
- Text Templates - Perform string manipulation and formatting.
- Value List Templates - Perform operations against value lists.
- Expression Designer Templates - Allows combining syntax rules with business language rules.
- Logical Templates - Perform logical operations.
- XML Templates - Perform operations against XML files.
- Validity Templates - Perform validations.
- Action Templates - Trigger actions.

Collection Templates
Collection templates perform lookup and aggregate functions over a collection. They can filter out specific collection members to operate over.

| the value of a member at an index | the value of <field> on member number <integer> from <collection> otherwise use <default> | field value |
Comparison Templates
Comparison functions evaluate to Boolean by comparing values to the left and right of the operator.

| is at most | <numeric> is at most <numeric expression> | Boolean |
| is between | <date or numeric> is between <date or numeric expression> and <date or numeric expression> | Boolean |
| is not between | <date or numeric> is not between <date or numeric expression> and <date numeric expression> | Boolean |
| is equal to |
<Field> is equal to <value> *value of same data type as left side of comparison |
Boolean |
| is not equal to |
<field> is not equal to <value> *value of same data type as left side of comparison |
Boolean |

Conditional Templates
Conditional templates evaluate the Boolean expressions in a list. Conditional templates are extremely useful for grouping multiple rule conditions and make it easy to add new conditions.

| less than | less than <number> of the following are true (or false) | Boolean |
| other than | other than <number> of the following are true (or false) | Boolean |

Append condition templates allow the rule conditions to be appended with other conditions.

The expression designer template allows users to build complex expressions using syntax rule functions. This feature enables the user to combine syntax rules with business language rules. This can be very useful for managing complex parenthetical formulas or functions that are not supported as business language templates.

| safe expression | <expression> otherwise use <default> | expression value |
Example:

Logical templates may be used to influence the evaluation of the conditional templates.

Validity Templates
Validity templates are used to check the validity of a Field or Entity, which may have been set from Constraints or the Mark Field As Invalid / Set Field Invalid action.
| Template name | Template format | Template format |
| is not valid | <field> is not valid | Boolean |
| is valid | <field> is valid | Boolean |
Action Templates
Action templates are used to trigger actions. There is no return type.
| Template name | Template format |
| activate rule set | deactivate rule set <rule set> |
| add collection member | launches syntax editor |
| copy collection | launches syntax editor |
| deactivate rule set | deactivate rule set <rule set> |
| execute database query | launches syntax editor |
| execute decision table | launches syntax editor |
| execute rule set |
execute rule set <rule set> w/ Parameterized Rule Set: execute rule set <rule set> using (ParamName = <value>) |
| execute REST service | launches syntax editor |
| execute web service | launches syntax editor |
| execute xpath query | launches syntax editor |
| fire notification |
fire notification <message> with the following settings as notification type <warning|error> associated with <field> |
| halt all rule execution | halt all rule execution and log message <message text> |
| halt rule set | halt rule set and log message <message text> |
| mark field as invalid* | mark <field> invalid and display message <text message> |
