It does not convey any other meaning than a positioning on the \"time-line\" of chronology. The Time-Span in turn is approximated by a set of dates (E61 Time Primitive). A temporal entity can have in reality only one Time-Span, but there may exist alternative opinions about it, which we would express by assigning multiple Time-Spans. Related temporal entities may share a Time-Span. Time-Spans may have completely unknown dates but other descriptions by which we can infer knowledge.\n\nExamples:\n- the Yalta Conference (E7) has time-span Yalta Conference time-span (E52)\n\nIn First Order Logic:\nP4(x,y) \u2283 E2(x)\nP4(x,y) \u2283 E52(y)"@en . <http://erlangen-crm.org/current/P4_has_time-span> <http://www.w3.org/1999/02/22-rdf-syntax-ns#type> <http://www.w3.org/2002/07/owl#ObjectProperty> . <http://erlangen-crm.org/current/P4_has_time-span> <http://www.w3.org/2004/02/skos/core#notation> "P4"^^<http://www.w3.org/2001/XMLSchema#string> .
