There are advantages to locked and unlocked Vocabularies:

  • When your rule development has many Rulesheets and Ruletests, you might want to add a measure of control over Vocabulary changes. Locking the Vocabulary prevents you from accidentally changing an entity or attribute, thereby invalidating rules and calls from databases.

You can choose to lock a Vocabulary in Studio by selecting the Set to Read Only option, as shown:



Once locked, all the icons in the Vocabulary display a padlock symbol.



In a locked Vocabulary, all functions in the Vocabulary editor are display-only, including Custom Data Types and Database Access. Undo (and Redo) options will toggle the mode until the Vocabulary file is saved.

A locked Vocabulary can be unlocked by selecting the Set to Read/Write option.
