The changes occurred within paradigms of research processes have turn open data into a key element that requires reconsidering the way our work is done and information is dealt with. This overhaul also aims at developing new cross-cutting and transdisciplinar approaches. 

This proposal introduces the methodology developed for the integrated management of historical data, considering the wide diversity of sources in order to ease collaborative work and make it accumulative along time.

The concepts of Topographic Unit (indicator of an action or place that can be located in space and time, regardless the specificity of the source of information and its biotic, abiotic or anthropic origin) and Actor (individual or collective author of an action), together with the use of an ontology applied to the information gathering and classification, and the definition of relationships are the underpinning pillars of this system.

The potential of further data exploitation via different tools such as statistics, graphical representation, geographic information systems, etc. is exemplified by results obtained from its application to different research projects carried out since 1997.
