Source accessed at The resource is related to a given source which was accessed or consulted (but not retrieved, imported or derived from). This access can be detailed with pav:sourceAccessedBy and pav:sourceAccessedOn. For instance, a curator (pav:curatedBy) might have consulted figures in a published paper to confirm that a dataset was correctly pav:importedFrom the paper's supplementary CSV file. Another example: I can access the page for tomorrow weather in Boston (http://www.weather.com/weather/tomorrow/Boston+MA+02143) and I can blog ‘tomorrow is going to be nice’. The source does not make any claims about the nice weather, that is my interpretation; therefore the blog post has pav:sourceAccessedAt the weather page.
