SMW queries currently support NOT '!' and LIKE '~' operators when querying the values of semantic properties.
Are there current plans to add a NOT LIKE (e.g. '!~') operator? This would significantly enhance the query capabilities, especialy when using SMW more like a CMS or for storing standardised data sets.
Since (from my limited understanding of the SMW code) the current operators get translated into their corresponding SQL statements inside a WHERE clause (not gets '!=', like gets ' LIKE '), it seems that adding another operator which is getting translated into ' NOT LIKE ' would be not that a large change.
It think that the main additions would have to be done in the following files: (besides some other)
Or are there any other problems related to that I'm not aware of?
