Community Research and Development Information Service - CORDIS


The IDAP project was funded by the European Commission under the fifth framework programme. The main reason for establishing the project is the great need for protection of the large collections of parchment which are recognised as being among the most valuable objects of our cultural heritage. This report is devoted to a presentation of the project background, aims, goals and research strategy. It includes a description of the IDAP website, data collection and sharing of knowledge, the IDAP network for professional users in research and conservation of parchment, and the plans for activities and development in the future. The report also presents an introduction to damage assessment of parchment, parchment during the process of manufacture, typology of damage of the parchment in codex form, characterisation of microbial damage and a basic introduction to the IDAP damage assessment strategy, the damage assessment programme and the results of visual damage assessment as well as a discussion on the principles and problems of diagnosis, damage assessment and experiments specifically for parchment, and a description of a model early warning system. The results of accelerated ageing experiments as tools in the study of deterioration and deteriorative factors are presented. Moreover, the results of the work of the study of damage to parchment at the microscopic to the molecular levels, using various complementary advanced analytical microscopical, chemical, physical and thermochemical techniques, are presented with suggestions for statistical analysis of the data. All the mentioned results and systems developed in the project are available on the Internet, enabling the contributors to the IDAP network to improve communication and dissemination of expertise and knowledge within conservation in the European Community and worldwide.
