New issue 101 by rich...@cyganiak.de: Add a void:TechnicalFeature to
indicate Memento support
http://code.google.com/p/void-impl/issues/detail?id=101
Memento is an HTTP extension that allows access to previous versions of a
resource.
http://www.mementoweb.org/
It is supported, for example, by DBpedia.
Should we define a void:TechnicalFeature to indicate Memento support?
