. . . . . . . . . "Previous version" . "The previous version of a resource in a lineage. For instance a news article updated to correct factual information would point to the previous version of the article with pav:previousVersion. If however the content has significantly changed so that the two resources no longer share lineage (say a new article that talks about the same facts), they can instead be related using pav:derivedFrom.\n\nThis property is normally used in a functional way, although PAV does not formally restrict this. Earlier versions which are not direct ancestors of this resource may instead be provided using the superproperty pav:hasEarlierVersion.\n\nA version number of this resource can be provided using the data property pav:version.\n\nTo indicate that this version is a snapshot of a more general, non-versioned resource, e.g. \"Weather Today\" vs. \"Weather Today on 2013-12-07\", see pav:hasVersion.\n\nNote that it might be confusing to indicate pav:previousVersion from a resource that also has pav:hasVersion or pav:hasCurrentVersion relations, as such resources are intended to be a long-living and \"unversioned\", while pav:previousVersion is intended for use between permalink-like \"snapshots\" arranged in a linear history.
