The business processes of monument protection prominently rely on geospatial and location based information and hence are an application domain for geomatics. Geomatical applications are increasingly realized using web-based geoprocessing services instead of classical GIS. This results in advantages of cost, quality and data integration. The Open GIS Consortium is well known to have published numerous international open standards for geoprocessing services, among others Geography Markup Language GML as an application of XML. GML defines extensible geometry and topology schemas for geospatial information, to be used as a basic framework for domain specific application schemas. In Germany such schemas were developed e.g. for the objects of the official AFISÒ-ALKISÒ-ATKISÒ information systems of the state survey and real estate cadastre (NAS interface specification) as well as for those of OKSTRAÒ, the official standard for the representation and exchange of road and transport data. The contribution briefly introduces the technological scene from conceptual modeling to the construction of the XML schemas. It wants to incite a discussion on the promises and the risks of an analogous approach to creating an formal ontology for the objects of the archaeological monument protection.
