Use the following guidelines when creating new nodes in the Vocabulary:
  • Domain, Entity, Attribute, and Association Role node names can contain only alphanumeric characters (letters and numbers), and underscores. However:
    • Domain, Entity, Attribute, and Association Role node names can not begin with a number.
    • Spaces are not allowed in Domain, Entity, Attribute or Association node names. If the preferred name is a combination of multiple words, then the underscore characters can be used to combine them into a single-word name.
    • Domain, Entity, Attribute, and Association Role node names can begin with an underscore.
    • Domain, Entity, Attribute, and Association Role node names can begin with either an upper or lower case letter.
  • No two Entities in the same Domain can have the same node name (case-insensitive).
  • Names of Operators (such as sum, floor, and month) can not be used as Entity or Domain node names. They can be used as Attribute or Association Role node names.
  • Custom Data Type names cannot use the names of any of the base data types (such as string, decimal, boolean). For more information, see Custom Data Types .
  • Names of aliases in the Scope section cannot match (case-sensitive) the node names of Entities in the Vocabulary.
  • No two Attributes/Association Role nodes in the same Entity can have the same name (case-insensitive).
  • No two Domains within another Domain can have the same node name (case-insensitive).
  • No two root-level Domains can have the same node name(case-insensitive).
  • No association can have the same name as an entity.
