Open History Map aims to display the changes that happened in the past both from a political as well as a social and topographical point of view. the storage of these multi-dimensional changes has an enormous impact on the way the map is visualized. For this reason we needed to develop a caching system that was on one side flexible enough to display a non-quantizable dimension (time) and give us the possibility to pre-cache the whole system into a distributable package for easy local usage and possibly fast update of the package. The caching system itself is backend independent and defines a process to simplify access to a mix of discreet (x,y,z) and continuous (t) identifiers for independently variating geospatial datasets.
