Central to the entire discipline of heritage restoration and conservation is the concept of information management. Nevertheless, traditionally, conservation and restoration has been a poorly documented discipline, which has led not only to a lack of standardization and awareness about the processes carried out in the past, but also poses problems both when new restoration works are necessary and for the preventive conservation of the elements of heritage. This study sets out to propose a conceptual framework to explore the relationship between conservation of heritage and information management on the basis of case studies; in particular: a spatial data infrastructure (SDI) of a regional government concerning an endangered plant (wild grapevine) with an important potential for cultural and touristic uses in a wine-making region; an open data guide—the Digital Guide of Andalusian Cultural Heritage; a university repository connected to Europeana, which contains reports and outcomes of projects of geometric documentation of elements of heritage; a repository of an organization in charge of the protection and care of the heritage; and finally, two examples of the use of heritage building information models (HBIM) in complex monuments. After discussing the characteristics of each case, this paper concludes that, although the availability of information and tools is growing, further progress is still necessary concerning the interoperability, outreach and reuse of the different solutions.

The consolidation effects of portlandite (CaOH)2 nanoparticles have been determined in carbonate stones (dolostone), typically used in historical buildings from Madrid, Spain, just after 20 days consolidation at 20°C under a dry [33% relative humidity (RH)] and a humid environment (75% RH) and after 18 months under room temperature and humidity conditions (20°C±5 and 50±10% RH). The improvement of the physical and hydric properties, from short to longer term, of this dolostone is shown through the combination of nondestructive techniques (environmental scanning electron microscopy, spectrophotometry, water absorption under vacuum and capillarity, ultrasonic velocity, and optical surface roughness analyses) together with destructive techniques (mercury intrusion porosimetry and microdriling resistance measurement) also necessary for a better accuracy determination of pore structure and resistance modifications. Consolidation process under both humid and dry environment gives rise to an improvement ...
