In this framework, EU-CHIC project aims to set-up a system introducing a concept of the “Cultural Heritage Identity Card”, which will develop into a systematic collection and storage of data on immovable heritage objects across European and neighboring countries. This work supports sustainable maintenance, preservation and revitalization of historic sites and monuments. This is achieved through the development of a guideline for the assessment of efficient documentation systems that identify the parameters needed for the characterisation of the preservation state of a monument and its possible alterations during its entire lifetime. In order to develop and test the recommendations for efficient compilation of the data pertinent to each monument under observation, the development of criteria, indicators and protocols as part of a common methodology that encourages the exchange of document between European countries is initiated. The criteria encompass all potential factors affecting the building structure, the non-structural elements, the architectural value and any other aspects ranging from the functionality of the monument/building, to its historic value. This has been achieved through an integrated survey of existing documentation protocols in the field of cultural her itage protection, and through implementation of recommendations about criteria for harmonizing these protocols, both which provide a new documentation methodology. This new methodology is an upgrade of current documentation methodologies, and responds to criteria and indicators for risk assessment and the technology state of diagnostics and data management. A guideline will provide the essential document for further development of European policies for the traceability of cultural assets and harmonization of criteria for the future maintenance of European Cultural Heritage. 1. INTRODUCTION Cultural Heritage Protection is a multidisciplinary field that relies heavily on data compilation and processing. In order to support the continual process of sustainable maintenance, preservation and revitalization of historic sites and monuments, there exists a pressing need to collect and record reliable data on European cultural heritage. However, this is often difficult to achieve. In this framework, the EU-CHIC project has been initiated and aims to set-up a system introducing the concept of the “Cultural Heritage Identity Card”, which will develop into a systematic collection and storage of data on immovable heritage objects across European and neighbouring countries. Recommendations for the assessment and application of efficient systems are developed that identify the parameters needed for the characterisation of the preservation state of a monument and its possible alterations during its entire lifetime. Such a concept is expected to have a significant cost benefit for cultural heritage owners and managers by using common parameters, and will increase the level of professional know-how in order to minimize the detrimental impact of lack of knowledge and expertise. Based on previous work and experience in the field by the National Technical University of Athens [1, 2], recommendations and strategies for monuments‟ documentation, harmonized with the existing European standards and codes are developed. In order to develop and test the recommendations needed for the efficient compilation of the data pertinent to each monument under observation, the first part of the work focuses on the _______________________________________________________________________________________ Geoinformatics CTU FCE 2011 179 development of criteria, indicators and protocols as part of a common methodology that encourages the exchange of document between European countries. The criteria encompass all potential factors affecting the building structure, the non-structural elements, the architectural value and any other aspects ranging from the functionality of the monument/building, to its historic value. This is achieved through an integrated survey of existing documentation protocols in the field of cultural heritage protection, and through implementation of recommendations about criteria for harmonizing these protocols, both which provide a new documentation methodology. This new methodology is an upgrade of current documentation methodologies, and responds to criteria and indicators for risk assessment and the technology state of diagnostics and data management. 2. STATE OF THE ART 2.1 Survey of existing documentation protocols There exists no established universal documentation protocol/system for cultural heritage. This has also been identified by COST C5 Action which concluded that there are great variations in the systems of establishing and evaluating data from buildings in the European countries. In general, the responsibility for collecting data depends on the administrative structure in each country. As part of the development of European-level integrated documentation protocols, a survey of existing documentation protocols was performed to assess the current state-of-the-art in this field. The EU-CHIC project partners [3] studied twenty-three information systems from eleven European countries (Belgium, Czech Republic, Germany, Greece, Italy, Luxemburg, Malta, Poland, Portugal, Slovenia, Spain) and Israel. The following table presents a brief description of the systems analysed.

Each one of these protocols follows unique procedures. However, these methodologies have been compared in order to draw conclusions concerning the best way to develop a hypothetically optimal procedure. This study focused on issues relating to the preservation and sustainability of Cultural Heritage, such as location of the building, monitoring processes, management, current state of preservation, materials and intervention techniques applied in the past, all aiming to document the complete history of the monument. The systems described in Table 1 are a compilation of two types of protocols: Documentation Systems and Risk Assessment Systems. Some protocols may belong to both types. 2.2 Other Information Systems Data about cultural heritage are being collected, managed and presented by many different bodies with varying purpose, range of coverage and level of details. International perspective is important in research and development, coordination of activities and standardisation. The international view and safeguarding approach is interesting in comparison to the current administrative approach of the national information systems and databases. Some of the well recognised approaches are the Core Data Index to Historic Buildings and Monuments of the Architectural Heritage [17], the UNESCO‟s World Heritage List [1Ř], the European Heritage Network [1ř], the Council of Europe [20], ICOMOS [21], the Getty Conservation Institute [22] and RecorDIM [23]. 2.3 European Policies, Standards and Directives Furthermore any recommendation and strategies developed for the establishment of a monument documentation guideline should conform to existing European Policies, standards and Directives. Tables 2 and 3 summarize respectively the main EC Policies and Directives, among those applicable to cultural heritage protection and management, with an impact on documentation. In addition to the above policies and directives, consideration should be given to the standard CEN/TC 346. European Committee for Standardization (CEN) is a major provider of European Standards and technical specifications [24]. It is the only recognized European organization according to Directive 98/34/EC for the planning, drafting and adoption of European Standards in almost all areas of economic activity. CEN's National Members work together to develop voluntary European Standards (ENs). The standard CEN/TC 346 has been recently submitted to the CEN Enquiry and concerns “Conservation of Cultural Property – Condition survey of immovable heritage”. As such it can also be considered as a guideline for a common and standardized procedure to describe the condition state of built heritage. The Technical Committee CEN/TC 346 aims to develop a European standard that gives guidelines for a condition survey of an immovable cultural heritage object. It states how an immovable cultural heritage object should be registered, examined, documented and reported on. 3. RECOMMENDATIONS AND STRATEGIES The survey on existing information systems at National, European and International level, as well as the detailed review of the state of the art on methodology and directives currently employed and applied in the field of documentation, both help to identify the most common and effective Methods and Tools for collection of data related to monument documentation. In addition, the critical issues for developing recommendations and strategies for directives, relating to cultural heritage protection, management and decision making are identified allowing the necessary adjustments to specific needs. The results are presented in Table 4. In order for any new guideline for monument documentation to be effective and widely applicable, not only it needs to be harmonized with existing European standards and codes but also, most importantly, be able to cater for the variety and the particularity of cultural heritage. This is achieved by selecting and integrating common criteria that formulate a dynamic archive, incorporating and supplying with information on the monument, during its entire life-time. The vital stage is the inclusion of all existing data concerning special building documentation, materials and building's structure, environmental factors, degradation mechanisms, diagnosis techniques and methods and intervention works as described above. A detailed description of the categories and subcategories presented in Table 1 will be included in the Final Report of the EU-CHIC project [3] pending feedback from the Network of Researchers (experts from all over Europe dealing with documentation protocols used for cultural heritage protection) and the Advisory Network (representatives of national authorities established in European countries, dealing with cultural heritage protection). It should be noted that documentation criteria and risk indicators identified within the existing protocols are focusing mainly on the macroscale of the monuments. In fact, they should not be limited to simply record information and risks associated with environmental dangers, human impact and natural hazards affecting the static/ structural state of the monument, but should include other factors such as the conservation state of the materials (i.e. not only the static/structural aspects of the building), the importance and distribution of cultural heritage, the impact factor of the hazards present, various socioeconomic parameters etc. Obviously, these factors cover different scales of the problem. In particular, there is a correlation between decay and damage of materials that often leads to the monuments pathology. Since the materials‟ state of conservation depends on their physicochemical and physicomechanical parameters and the materials‟ behavior in a corrosive environment is not _______________________________________________________________________________________ Geoinformatics CTU FCE 2011 181 generalized, the risk assessment should be dealt in the direction of revealing the specific active decay mechanism with an integrated decay study both in mesoscale [type of decay (morphology)] and microscale [kinetics of the phenomenon (decay rate) and thermodynamics of the phenomenon (susceptibility to decay)] level, through a Standardized Diagnostic Study Methodology [37, 38].

It should also conform to the following requirements: Observance of the deontology of international conventions that demand the preservation and presentation of historic, sentimental virtues and the architecture of monuments, while preserving the authentic materials, forms and structures. Serviceability of the conservation interventions and restorations (so that the building can accept safely the new uses and face the earthquake risk) Compatibility of the materials and conservation interventions with authentic materials, the building and its environment Sustainability (Increase of lifetime, protection of the environment and energy savings, minimization of environmental impact on the monument) Therefore, it has become obvious that the proposed guideline should not be a simply integration of existing projects, instead it should build upon current experiences and existing knowledge, encompassing all potential data regarding building structure, non structural elements, architectural value and all other aspects from functionality to historic value. 5. CONCLUSIONS A combination of scientific, architectural, historic and cultural knowledge and experience of building conservation is indispensable for the study of all immovable cultural heritage objects reversing the current trend in focusing on specific aspects of documentation. An effective documentation protocol should be able to respond to the necessity of performing inspection, diagnosis and intervention works, leading to knowledge based decision making procedures. Based on existing initiatives, policies and directives that determine the established practice in the field of cultural heritage documentation, criteria were derived that will allow any new guideline for monument documentation to be harmonized with existing European Standards and codes. Such a standard methodology for monument documentation could bring the following advantages: a) Standardized methodology in the EU countries means comparable data on the condition of Cultural Heritage in Europe, b) Standardized data/ outputs are comparable (this means clearly defined database entry without any further need for definition) and c) Translation of the standard by a national standardization committee provides a unified terminology. In this context, the development of recommendations and strategies, as described in this work, is a vital step in establishing a guideline for monument documentation that will offer a unified methodology at a European level. 6.
