Hello, I would like to be able to use OWL2 datatype restrictions, but cannot figure out how to do this with TBC. For example, I would like to have a value like '8.4' count as a minimum exclusive value while defining a class as equivalent to the class having this minimal inclusive value for the datatype property in question. I have pasted the W3C explanation of this below. It is from Owl2 New Features and Rationale.
I would also like to be sure that I understand how one can do qualified cardinalites as restrictions on a property. It seems to allow me to type that in, but there is no icon for it in the dropdown via rightclick while formulating the restrictions. is it simply enough to type "HasPart 8 X" where 'X' is a class? Any help will be greatly appreciate. Best wishes, Leonard DatatypeRestriction also makes it possible to specify restrictions on datatypes by means of constraining *facets*<http://www.w3.org/TR/2009/REC-owl2-syntax-20091027/#Datatype_Maps>that constrain the range of values allowed for a given datataype, by length (for strings) e.g., minLength, maxLength, and minimum/maximum value, e.g., minInclusive, maxInclusive. Extended datatypes are allowed in many description logics and are supported by several reasoners.
