Expression Syntax

Expressions use double curly braces.

{{value_name}}

Examples

academic_period={{current_term}}
graduates_{{current_term}}_{{yyyymmdd}}.csv
https://example.edu/report?run={{run_id}}

Recommended rules

• Use named values.
• Avoid generic {{artifact}}.
• Keep value names clear and lowercase.
• Prefer snake_case names.
• Use expressions only in fields that explicitly support expressions.

Legacy artifact expression

Legacy expression:

{{artifact}}

Preferred replacement:

{{current_term}}

or another explicit named value.
