15. Internal Information Exchange Santander Group is evaluating the possibility of using XBRL in their internal processes. The idea would be that the communications between systems could be carried out with XBRL. The processes of information exchange that are currently carried out between systems by means of plain text (or any other simple format) interfaces, would be done in XBRL. Advantages: • The language becomes unified internally. • All the systems / applications would be in disposition of communicating with the exterior without having a conversion process. • It improves validation processes of the sent information. Inconveniences: • High initial cost of transformation. • Complex technical solution for different platforms. • Possible impact in intermediates tools for exploiting information.
