Abstract:
Interoperability has become fundamental to the management and sharing of the data. For this reason,
international standards are published and ontologies are proposed and used for structuring databases in order
to assure information retrieval, improved analysis and correct interpretation of the data, besides the
interoperability of compliant databases. For thematic data about cultural heritage, standards vocabularies and
ontologies EXIST, but are not fully suitable to represent some aspects of architectural heritage. In fact,
complex spatial data have to be equally managed using these technologies, for enabling analysis empowered
by the inclusion of the spatial and geographical dimension. This could undoubtedly enrich the documentation
of architectural heritage. However, few spatial ontologies exist, which are able to correctly represent the
complexity and richness of such data. In the paper, an existing ontological model for cartographic urban
themes, OGC CityGML, is extende
d, in order to propose a data schema for the management of architectural
heritage multi-scale, multi-temporal and articulated data. The extended parts of the model are explained in
the paper. Moreover, some implementation aspects are considered both for the definition of the ontological
schema extension and for the management of the data using it.
