Martin,


These are comments that are not based on implementation practices, just 
from my naive ontology engineering perspective.

The label should be "NewClassName" (or even "New Class Name"@en) and the 
note should rather be in a rdfs:comment.

foo:NewClassName rdfs:label "New Class Name"@en;
                  rdfs:comment "This was foo:LongClassName previously. 
foo:LongClassName is now deprecated and foo:NewClassName should be used 
instead."@en .

Same as above: keep the rdfs:label and add rdfs:comment "This class is 
now deprecated, use foo:NewClassName instead."@en

> foo:LongPropertyName1 a owl:DatatypeProperty ; owl:deprecated true;
> rdfs:domain foo:LongClassName ; rdfs:label "LongPropertyName1 -

>
> foo:LongPropertyName2 a owl:ObjectProperty ; owl:deprecated true ;

You can also add:

foo:LongClassName a owl:DeprecatedClass .
foo:LongPropertyName1 a owl:DeprecatedProperty .

which are defined in OWL 1 and 2.
