#before_validation ⇒ Object

If the identifier is not set, generate it before validation takes place. See Annotations::Config::default_attribute_identifier_template for more info.

The rules are:

  • if an identifier is manually set, nothing happens.

  • if no identifier is set:

    • if name is enclosed in chevrons (eg: <http://…>) then the chevrons are taken out and the result is the new identifier.

    • if name is a URI beginning with http:// or urn: then this is used directly as the identifier.

    • in all other cases the identifier will be generated using the template specified by Annotations::Config::default_attribute_identifier_template, where ‘%s’ in the template will be replaced with the transformation of ‘name’ through the Proc specified by Annotations::Config::attribute_name_transform_for_identifier.
