**IRI:** http://geovocab.org/spatial#C

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
in the RCC theory.

**IRI:** http://geovocab.org/spatial#DC

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

amounts of data, a closed world assumption may also be possible. More precisely, by considering not explicitely connected regions as discrete
regions. Moreover, discrete regions, which are not explicitely labeled as externally connected, would be considered disconnected from

**IRI:** http://geovocab.org/spatial#EC

Relation EC(x,y), read as 'x is externally connected with y'. This relation holds, when the two regions share at least
one common point of their borders, but share no points of their interiors, i.e. they do not overlap.

**IRI:** http://geovocab.org/spatial#inconsistentWith

Although this relation is not a part of the RCC theory, it has been introduced in order to detect relations between regions
which are inconsistent with the RCC axioms.

**IRI:** http://geovocab.org/spatial#NTPP

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

**IRI:** http://geovocab.org/spatial#P

Relation P(x,y), read as 'x is a part of y', holds whenever the region x is contained within the borders of the region y.

**IRI:** http://geovocab.org/spatial#PP

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
region y, and region y is not contained within the borders of the region y, which means they are not equals.

Relation TPP(x,y), read as 'x is a tangential proper part of y'. This relation holds, whenever a region x is
labeled as a proper part of a region y, and they share at least one common point in their borders, which means that they are
externally connected.
