The Task Group 2 "Open Source in use for the cultural heritage communication process" [1] is hosted by CIPA, the International Committee for Architectural Photogrammetry, one of the international committees of ICOMOS (International Council on Monuments and Sites). The main targets of the Task Group are related to the study and dissemination of the Cultural Heritage, considered from a wide perspective according to UNESCO's definition [2], and the current EU legal framework.

This scope includes "the entire corpus of material signs –either artistic or symbolic- handed on by the past to each culture and, therefore, to the whole of humankind" [3]. Thus, Cultural Heritage consists of more than *monuments* (architectural works, sculpture and painting elements, archaeological structures, ancient books, manuscripts, maps and charts), but of *groups of buildings* (historical towns, industrial heritage, historical infrastructures), and *sites* (cultural landscapes, natural values). Physical artifacts and intangible attributes inherited from past generations must be maintained for the future generations, and accordingly, their knowledge must be widely disseminated.

Due to the different particular types of cultural objects, different approaches, tools and techniques must be developed to get an accurate knowledge of them. Aspects and disciplines concomitant with the preservation and conservation of tangible and intangible culture include archival science, art and architectural conservation, audio recording, digital data collection, storage and management, and architectural, urban and landscape drawing, among others. From a multidisciplinary approach, the Task Group 2 aims to develop an intensive promotion of Open Source software as free alternate tools for all researches on Cultural Heritage, which are useful in every stage involved in the processes of knowledge, documentation, management, and dissemination of cultural heritage.

In a first epoch the Task Group 2 initiative was successfully chaired by Markus Jobst, of Research Group Cartography at Vienna University of Technology (Austria). Currently we are starting a new era chaired by Prof. Pilar Chias, at the University of Alcalá (Spain).
