"Relation C(x,y), read as 'x is connected with y'. This relation holds when two regions share a common point. It is the primitive relation\n\t\t\t\tin the RCC theory." .

"Relation DC(x,y), read as 'x is disconnected from y'. In order to prevent an exponential growth of triples when handling large\n\t\t\t\t amounts of data, a closed world assumption may also be possible. More precisely, by considering not explicitely connected regions as discrete\n\t\t\t\t regions. Moreover, discrete regions, which are not explicitely labeled as externally connected, would be considered disconnected from\n\t\t\t\t eachother." .

"Relation NTPP(x,y), read as 'x is a non-tangential proper part of y'. This relation holds, whenever a region x is \n\t\t\t\t\t\t\t labeled as a proper part of a region y, and they do not share common point in their borders." .

"Relation PP(x,y), read as 'x is a proper part of y', means that the region x is contained within the borders of the \n\t\t\t\tregion y, and region y is not contained within the borders of the region y, which means they are not equals." .
