3(4) data models and their opportunity for relevant heritage analyses under a preventive conservation approach

Abstract

Preservation of cultural heritage is progressively linked to regular maintenance and a continuous monitoring; both activities will define what is known as preventive conservation. This paper discusses the design of a conceptual model for a heritage monitoring system as a support to preventive conservation practices in World Heritage Properties. With respect to these properties the design of the proposed system starts by the choice of a data model, which is determined by different requirements. In heritage conservation, these requests are based on the values and attributes of analyzed elements. They will allow to the system the act of measuring change in the state, number or values presence. Within this framework, a conceptual model is proposed, showing how values and characteristics of heritage elements can be translated into data requirements, how these data requirements define a data model, how this data model determines the database to finally established , how the database determines the best choice for a Geographic Information System (GIS). The paper was illustrated for building blocks in Cuenca and it gives an insight into requirements and potentials of a heritage monitoring system able to combine complex information in spatial reference system valuable to public administration (site managers) for more informed decision making and management strategies. For Cuenca and other world heritage sites, the link made between technology (databases + GIS) and heritage requirements has the objective to overcome the existing gaps and to promote a more nimble heritage management.
