The cultural heritage artifacts Conservation Documentation is not universally agreed upon nor has it always been considered an important aspect of the conservation profession. Conservation records present major drawbacks, which are the fragmentary and incomplete description of the contained information and related processes. On the other hand, art works and monuments of great historical value are subject to examination only through Non-Destructive Testing and Evaluation (NDT&E) techniques. In this context, the present paper presents the DOC-CULTURE project approach to standardize the documentation of the conservation and the NDT&E methods and their output data through CIDOC-CRM extension.
