“…Since the validity of the topological relation depends on the semantic of the entities topo-semantic constraints are a subtype of the general semantic IC defined by [9]. In [4] topo-semantic constraints are subdivided into semantic and user defined constraints. The former are based on the nature and the physics of the objects, e.g.…”

“…A further subdivision of SIC can be made by grouping the restricted properties corresponding to their semantic domain. Extending the approaches of [1] and [4] we do not only consider topological relations. The categorisation (see figure 1) includes thematic, temporal, spatial and change relations as well as relations for the connection between multiple representations of an entity.…”

“…In the last decade much research has been done in the area of GI quality assurance with integrity constraints [1] [2], IC definition, formalisation, exchange and management [3] [4][5] [6] and validation of internal consistency of IC sets [7]. Nevertheless most of these approaches only consider specific types of IC.…”

Integrity constraints play a major role when the logical consistency of a data set has to be evaluated during quality assurance. The paper reviews established approaches of integrity constraint classification and proposes a profound categorisation which distinguishes semantic integrity constraints according to the semantic domains of the involved properties. The categorisation provides the preconditions for formalisation and the identification of conflicts and redundancies in sets of integrity constraints. Therewith the management and usability of integrity constraints will be improved which will also result an improvement of spatial data quality.

“…One of the things the current paper sets out to do is refine this taxonomy. Cockcroft [5] also argued that an integrated approach to handling integrity constraints entails developing a repository of data and constraints. The conclusion is that constraints should be part of the object class definition, like other aspects of the definition such as attributes, methods and relationships (generalisation/specialisation, part/whole and associations).…”

Constraints are important elements of every modelling process, but until now they have been treated in an ad hoc manner, depending on the specific application domain and the capabilities of the tools used. In GIS and GeoVR applications, constraints are conditions which always have to be valid (true) within the model populated with real geographic object instances. This paper argues that constraints should form a systematic part of the object class definition, similar to other aspects of the definition, viz. attributes, methods and relationships. Also, the implementation of constraints in all GIS and GeoVR subsystems (at front-end, database and exchange (I/O) level) should be derived automatically from the constraints specified by the framework. The paper therefore puts forward a framework for modelling constraints comprising (1) a classification and clarification of constraints, (2) a formal description using the unified modelling language/object constraint language (UML/OCL) and (3) implementation characteristics. The components of the framework are illustrated and applied to SALIX-2, a geo-virtual reality (GeoVR) landscape modelling system.

“…Spatial relationships and constraints are very important in spatial databases [10,11] because the spatial objects are embedded in a same geographical space. A Spatial Whole-Part relationship (called SWP relationship in the sequel) is a Whole-Part relationship in which whole and parts have a spatial extent and a topological constraint is defined between the spatial extent of the whole and the spatial extents of its parts that imposes a topological relationship among them.…”

The important role of Spatial Whole-Part relationships in spatial database design is widely recognized and several researches have proposed specific spatial models to classify these relationships and their related topological constraints.The recent ISO-TC211 standards have defined a spatial data model and its use in spatial database design. However, the modelling of topological constraints of Spatial Whole-Part relationships requires additional complex and counterintuitive expressions specified by using a formal constraint language.This paper shows the complexity of modelling Spatial Whole-Part relationships in ISO and proposes an approach for the definition of ISO conformant modelling abstractions which hide this kind of complexity to the database designer. This approach is applied to the definition of the modelling abstractions for Spatial Whole-Part relationships which cover all the Spatial Whole-Part relationships proposed in the literature.
