Official repository of the Extended Matrix formal language The Extended Matrix (EM) is a scientific method and formal language for the Cultural Heritage domain. It is based on knowledge graph networks and grounded on FAIR and Open Science principles. EM formalises complex interpretative philological phenomena such as virtual reconstructive hypotheses in a transparent and robust manner; EM enables verifiability of results, reusability of data and collaborative interpretation. EM allows experts involved in reconstructive processes to: organize the complexity of reasonings behind; map the sources employed; support the compatibility of reconstructive pipelines with other ontologies; declare the reliability of your final proposals; present your final results both as a graph-of-knowledge and a series of 3D models; The original GitHub repository of the EM formal language can be found here Channel to join the community of users Telegram open-group For more details see the EM website References The main bibliographical reference (open access) of this first "core" version of the EM (1.0) is: *Demetrescu, Emanuel. 2015. «Archaeological Stratigraphy as a formal language for virtual reconstruction.
