    1.11 +		The datatypes <http://strdf.di.uoa.gr/ontology#period> and <http://www.w3.org/2001/XMLSchema#dateTime>
    1.12 +		are used to represent periods and instants respectively.
    1.13 +	
    1.14 +		The valid time time of triples is represented using quadtruples, with the valid time
    1.15 +		annotation(instant or period) being the fourth element of the quad. In the same way, 
    1.16 +		temporal triple patterns are used in queries to retrieve the valid time of triples.
    1.17 +		
    1.18 +		Some functions have been renamed (their URIs have changed) to follow the names of the 
    1.19 +		respective relations of Allen's interval algebra and other functions have
    1.20 +		been added. 
    1.21 +		
    1.22 +		The following temporal functions are supported:
    1.23 +		during, periodOverlaps, equalsPeriod, nequalsPeriod, adjacent, before, ,after,
    1.24 +		 overleft, overright, meets, starts, finishes, 
    1.25 +		period_intersect, period_union, preceding_period, succeeding_period.

    1.27  	* Changed behaviour of Strabon and Strabon Endpoint for connecting to
    1.28  	a spatially-enabled database. Only one instance of Strabon is allowed
    1.29  	at a time.
