The medieval historian and geographical space

The geographical space is a concept allowing one to describe, understand, and explain a concrete object: the space of the earth. The study of that space long remained restricted to an repertory of places and then to an assesment of regional features, before becoming centered, in more recent years, on spatial analysis practices: following the example of Peter Haggett, the medieval historian endeavoured to reveal the distribution of spatial objects, to analyse in terms of topological closeness, and contiguity.

The GS became widespread following the implementation of georelational software in the early 1980s. This software deals with the topology of geographical objects. The concept of geodatabase, which François Bouillé developed in his doctorate thesis in 1977, became operational in 2000, thus allowing the physical implementation of data conceptual models made according to the HBDS method.

The HBDS method.

François Bouillé theorised the modelisation method HBDS (Hypergraph based data structure) in his doctorate thesis entitled (Un modèle universel de banque de données simultanément partageable, portable, répartie(, Université de Paris VI, 1977. This method consists in deconstructing the complexity of reality into simple phenomena according to a given problem. Inspired by hypergraphic and ensemblist theories, HBDS allows one to represent in the shape of graphs and hypergraphs, classes and hyperclasses, links and hyperlinks, the internal structure of these simple phenomena.

The medieval Church is at the same time a community sharing the same destiny, a juridical and political machine and a collection of places of worship. Therefor, measuring the impact of the papal schism upon the Church amounts to studying the evolution of the spatial relations between the establishments, jurisdictions, and individuals. The geodatabase obediences.net© was created within the CRN M2ISA in order to: - check the veracity of the model « one principality, one papal obedience »
? measure the various uses of the papal grace
? analyse the movements over a carreer within one given border space.
Until a webmapping module is made available online, the files extracted from the geodatabase ca be accessed using various forms to fill in.
