Errata for Protégé OWL Tutorial Version 1.2

This is the errata page for version 1.2 of the Protégé OWL Tutorial.

Protege 4.x is under heavy development so it is difficult to keep such a comprehensive document completely up-to-date.

If you find that the most recent version is not in sync with the tutorial, please let us know so that we can update the errata.

We can then use this page when we incrementally update the tutorial and your contributions will allow this to be done more easily.

When reporting errors please give a location where possible (page number, section/paragraph, figure number, etc).

Misleading or out of date

page 74, Exercise 43, step 3 onwards	Creating a defined class in this way will not produce the desired effect - InterestingPizza will end up being equivalent to `Pizza` and also equivalent to `hasTopping min 3` (there will be two separate equivalent classes). Instead, a new superclass should be added `hasTopping min 3` and then InterestingPizza can be correctly converted to a defined class.
page 76, Exercise 45, step 1	Ignore step 1. Simply create a subclass of `Pizza` by whatever method preferred.
page 78, Exercise 47, step 3	`Margherita.` should be `MargheritaPizza`.
page 81, Exercise 49, step 4	The repetition of Pizza is unnecessary. This should be: In the Class expression editor, type `hasCalorificContentValue some integer[>= 400]` and click OK.
page 94, Exercise 60, Figure 7.4	Country will simply be equivalent to `{France, Italy, England, America, Germany}`
