This is something that we intend to enable *at some point* but we first need
to extend/improve the internal architecture for managing special property
values.
Regarding the original request, however, there are two possible workarounds.
SMW does not support negation, so you cannot exclude pages based on
properties they do have. You can, however, exclude pages based on properties
that they fail to have, and this may suffice:
* If every person as a unique name, say {{{Full name}}}, then you can make a
query
{{#ask:
[[Category:Person]]
[[interest::{{{interest}}}]]
[[full name::!{{{Full name}}}]]
}}
This finds only pages that have some full name is different from the name of
the current person. Of course, if two people have the same name or if one
person has two distinct names, then it would fail. A more secure method would
be to have a "hidden" (non-special) property that always gets the value
{{FULPAGENAME}}. This could be hidden in a template, and hence would emulate
the special property that was suggested.
There is a second option:
* If the query results are very limited, you can use template-based formatting
to filter out certain results. Using #ifeq you can always check if a result
is equal to the current page name, and exclude it in this case. This is
probably not a good idea for very long lists of results, but it gives you a
lot of formatting power otherwise.
