Property:Has instance

'''Note: Instance-of-relations are specified by the MediaWiki category system&mdash;a category like "Airports" has instances. See Property:Is a for more discussion and do not use this annotation to workaround the faster, more powerful, and better supported category system. Send me an email if you think this needs discussion.''' --Markus Krötzsch 20:04, 30 October 2006 (CET)
