Date Model: Event

Events are typically modeled like this:

<#event>
    rdf:type [some event type] ;
    gc:date [some date] ;
    gc:place [some place] ;
    gc:hasRole <#role1> ;
    gc:hasRole <#role2> .

<#role1>
    rdf:type [some role] ;
    gc:playedBy <#person1> .

<#role2>
    rdf:type [some role] ;
    gc:playedBy <#person2> .

The number of players is unbounded. Also, there is a hierarchy of roles, some being primary, others major, and so on, allowing software to better operate on custom event types.
