Add support for anonymous class assertions in templates

Individual Template Strings

If the TYPE is a defined class, owl:Individual, or owl:NamedIndividual, an instance will be created. If the TYPE does not include a defined class, that instance will have no class assertions (unless you use the TI template string to add an anonymous type). You may include a SPLIT= in TYPE if you wish to provide more than one class assertion for an individual.

• class assertion:
  • TI %: the individual will be asserted to be a type of the class expression in the column
• individual assertion:
  • I <property>: when creating an individual, replace property with an object property or data property to add assertions (either by label or CURIE). The value of each axiom will be the value of the cell in this column. For object property assertions, this is another individual. For data property assertions, this is a literal value. If using a property label here, do not wrap the label in single quotes.
  • SI %: the individual in the column will be asserted to be the same individual
  • DI %: the individual in the column will be asserted to be a different individual

Example of Individual Template Strings

Label	Entity Type	Individual Role	Property Assertions	Different Individuals
LABEL	TYPE	TI 'has role' some %	I part_of	DI %
Individual 1	Class 1	Role Class 1	Individual 2
Individual 2	Class 1	Role Class 2		Individual 1
