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.

<p class="VARAbstract">The concept of mock-up, which share with the drawing the expressive synthesis for the analysis of the architectural form and evolution, is an invaluable asset for the preservation of the heritage. To mark the 175^th anniversary of the Práxedes Mateo Sagasta’s secondary school of Logroño (Spain), an exhibition about the history of the institution was organized at the premises of La Rioja Library. The current school building became operational in 1900 and was built on the former site of a Carmelite convent. In fact, the convent rooms were the first location for the school, after the expropriations of religious communities during the mid-19th century. For the benefit of the aforementioned exhibition, it was considered interesting to generate a three-dimensional (3D) virtual reconstruction of the convent buildings to show how it would have looked. However, the lack of sufficient contemporary graphic information was a challenge, so it was decided that an efficient solution would be to generate the virtual reconstruction from a paper craft model, which had been created by the librarian of the secondary school as a result of his research on this matter. This text describes the 3D modelling of that cut-out element by means of monoscopic photogrammetry (perspective drawing) and the use of non-realistic rendering based on the appearance of the paper mock-up (and not trying to recreate the real image of the buildings) so as to provide a suggestive view of the convent and create interactive exhibition items. Moreover, the text deals with the long-term preservation and the improvement of the re-use of the 3D models. The former by resorting to institutional repositories —from which users can download the full detailed versions— and the latter employing versions able to be visualized in 3D warehouses (such as Sketchfab) and augmented reality (AR) applications.</p><p><strong>Highlights:</strong></p><ul><li><p>A significant part of the architectural heritage is represented by mock-ups of different materials (paper, wood, metal and so on).</p></li><li><p>Virtual modelling and augmented reality (AR) can be appropriate tools for materializing, recovering and disseminating scale models to the public.</p></li><li><p>Techniques for geometric documentation and visual representation need to be adapted in order to tackle the peculiar features of these elements (size, materials, fragility, etc.).</p></li></ul>

En el debate sobre el empleo de redes sociales y/o repositorios institucionales para difundir los trabajos e investigaciones relativos al patrimonio cabe incluir una reflexión sobre los modelos 3D. La existencia de plataformas comerciales específicas para el almacenamiento, visualización interactiva y descarga (gratuita o de pago) es, hoy por hoy, una actividad pujante, siendo un claro ejemplo de ello, Sketchfab®. Frente a esta línea de acción, los repositorios institucionales, así como los agregadores (como es el caso de Europeana) también están dando pasos en la dirección de considerar este tipo de documentos y aportar funcionalidad a los usuarios para que puedan localizarlos y reutilizarlos de manera conveniente. El presente texto, expone brevemente la situación de ambas líneas y reflexiona sobre las posibilidades de utilización combinada que, a nivel interno, puede emplear una organización cultural con el fin de obtener el máximo rendimiento.

La documentación de las intervenciones de conservación-restauración del patrimonio engloba los procesos metodológicos y los registros generados antes, durante y después de las mismas, influyendo en la preservación del patrimonio. El objetivo de esta investigación es analizar el contenido de las recomendaciones y normativas que enmarcan estos procesos, estudiando su evolución hasta la situación actual, tanto en el ámbito internacional como nacional.  Para ello se analiza la doctrina internacional, la Ley del Patrimonio Histórico Español, las leyes autonómicas y el anteproyecto de reforma de la LPHE. Los resultados muestran que, en la doctrina internacional, las normativas amplían y complementan las anteriores. En el caso de España, cada comunidad autónoma dispone de leyes territoriales que determinan los procesos de intervención que han de disponer de documentación, aunque con diferencias entre ellas. Finalmente, las actualizaciones normativas recientes presentan la tendencia a incluir la documentación de la conservación-restauración, y a incorporar programas preventivos, como un requerimiento dentro del proyecto de intervención.
