Hey folks, there's a group of data repositories interested in publishing a temporal extent that expresses a seasonal coverage across multiple years. Rather, they want to express that data was collected in an aggregate of multiple intervals. 

The use case for an extension to OWL-Time for this case is driven by search precision and recall. For example if the data were collected in June, July and August across the years 2012 to 2015, a temporal interval extending from 2012 to 2015 would hit as a match for a search looking for data between January 2013 and May 2013 which would be wrong in this case.  

In discussions with @dr-shorthair , he recommended a small extension of one class and one property:

```
time:TemporalAggregate rdf:subClassOf time:TemporalEntity .

time:hasMember a owl:ObjectProperty;

                rdfs:domain time:TemporalAggregate ;

                rdfs:range time:TemporalEntity . 
```

With this aggregate class, we can express a collection of Temporal entities that explicitly describes the collection activity. 

Thoughts?
