The CEN has acknowledged the need for something like this (see CEN/TC 287, which specifies names and semantics of required spatial operators), but so far no complete proposal exists.
The standard was drawn up by CEN in co-operation with digital map providers, automotive and electronic equipment manufacturers. The outcome of these standardisation efforts (CEN GDF 3.0) has formed the major input to the world standard ISO GDF 4.
GDF means Geographic Data Files, It is a standard data exchange format and a data model (a complex data model). It is used to describe road networks & road-related data and is an international standard ISO/TC204 / CEN/TC 278.
