Most vocabularies are now StrictVocabularies meaning that an attempt to resolve a particular term in that vocabulary will error if the term is not defined in the vocabulary.
 * New vocabulary definitions have been added for [ICal](http://www.w3.org/2002/12/cal/icaltzd#), [Media Annotations (MA)](http://www.w3.org/ns/ma-ont#), [Facebook OpenGraph (OG)](http://ogp.me/ns#), [PROV](http://www.w3.org/ns/prov#), [SKOS-XL (SKOSXL)](http://www.w3.org/2008/05/skos-xl#), [Data Vocabulary (V)](http://rdf.data-vocabulary.org/), [VCard](http://www.w3.org/2006/vcard/ns#), [VOID](http://rdfs.org/ns/void#http://rdfs.org/ns/void#), [Powder-S (WDRS)](http://www.w3.org/2007/05/powder-s#), and [XHV](http://www.w3.org/1999/xhtml/vocab#).
