Abstract
Object oriented databases provide rich structuring capabilities to
organize the objects being relevant for a given application. Due to
the possible complexity of object structures, path expressions have
become accepted as a concise syntactical means to reference objects.
Even though known approaches to path expressions provide quite elegant
access to objects, there seems to be still a need for more generality.
To this end, the rule-language PathLog is introduced. A first
contribution of PathLog is to add a second dimension to path
expressions in order to increase conciseness. In addition, a path
expression can also be used to reference virtual objects. Both
enhancements give rise to interesting semantic implications.
