for a river selection, specific constraints for AGENT or CartACom,

Figure 5: CollaGen allows interoperability with the use of a single output, constraints and
the translator.
The translator also serves as a registration mapping (Lemmens 2008) to
tag the geographic data with the corresponding ontology concept: it makes
the mapping between the “IGN_BUILDING” data class and the “building”
ontology concept for instance (Touya et al. 2010). Finally, the translator
allows to map the formal constraints with measurement algorithms that
compute the constraint current value and satisfaction for a given object as
in AGENT (Barrault et al. 2001). The use of such mechanism is detailed in
§0.
Registry Component
The registry serves as yellow pages service to choose a relevant process to
generalise a given space at a given time. To a request like 'what are the
best available processes to generalise rural space n°x?' the registry
responds with a list of applicable processes sorted by relevance (e.g. 'Cart-
ACom, Least Squares, AGENT').
To build the list, the registry first selects the relevant processes according
to their description pre-condition: if the pre-condition, a list of space types
