A computer implemented method for consolidating at least one key indicator of a virtual object receiving a description of at least one key indicator of the virtual object, receiving a set of attributes (ATT) of the virtual object, receiving a data model (DM) for indexation of said virtual object, receiving a set of rules (RUL) to convert the attributes of the virtual object (OBJ) into the data model (DM) for indexation, applying the set of rules (RUL) to convert said attributes into the data model (DM) for indexation, transforming the data model (DM) for indexation into a directed acyclic graph, and consolidating said key indicator based on an expansion of the directed acyclic graph.
