Character Set Rules

The encyclopedia maintains the same uniqueness, length, and character set rules that are enforced by the workstation. When you check out a subset, you can add new objects or can rename existing objects that are unique within the subset, but cannot be unique within the entire model on the encyclopedia. The upload process ensures an added or modified object name is unique within the model. When it is not unique, the upload process derives a unique name.

Note: For more information about rules, see the Encyclopedia API Reference Guide.

This section lists the objects and the rules that apply to each object.
