Thanks for your comment. It would be very helpful if you could find a
couple of examples of this to inform the working group, and to send
this comment to email@example.com so that it can get the
official attention of the working group, who would then consider the
While I can pass the comment on informally, the working groups isn't
obliged to take it up (which it should) unless the message is sent to
the aforementioned mailing list.
I can offer a couple of comments that represent my own views, not
those of the working group and perhaps these may be helpful.
The first thing is that I'm nor sure if you are commenting on the
extensibility of the Manchester Syntax, on the expressivity of OWL, or
on the user interface of Protege, and it would help if this could be
made clear. If a comment on Protege, it is outside the scope of the
WG. If a comment on extensibility of Manchester Syntax (I note the
current version says "The only datatypes allowed are the built-in OWL
2 datatypes.", then this should be made clear, although the ability to
extend the syntax is no guarantee that the syntax *will* be extended
by someone. If a comment on OWL expressivity, note that it may be
possible to use annotation properties and annotation property ranges
for this purpose. See
http://www.w3.org/2007/OWL/wiki/Syntax#Annotations. OWL annotation
values may be any URI, and the annotation properties are ignored in
the OWL semantics. Similarly annotation property ranges are ignored
but might be used to express the intent that the range of an
annotation property have a range of the custom datatype.
Perhaps with some consideration of these comments you could send your
original or a revised note to firstname.lastname@example.org.
