[EN] Since the beginning of the discipline, eLearning has been about innovation. New
software, systems, contents and tools are being created and experimented with and in constant
evolution. But when systems, contents and tools become successful and part of the regular
infrastructure of educational institutions, interoperability becomes an issue. Systems that are
consolidated and regularly used need to be able to interoperate with new ones. And the new
tendencies need to fit within the current infrastructure. This paper states how several research
and development projects with heterogeneous funding sources and locations worldwide,
gathered together to find a solution to this common problem, providing open specifications and
standards, plus Free/Libre, Open Source reference implementations.
[ES]Desde el principio de la disciplina, el eLearning ha sido un campo novedoso que ha generado nuevo software, sistemas, contenidos y herramientas con los que se está experimentando. la interoperabilidad se convierte, en este contexto, en un problema. Los sistemas consolidados y empleados regularmente tienen que ser capaces de interoperar con otros nuevos. Este artículo trata sobre cómo varias investigaciones y lproyectos de desarrollo se reunieron para encontrar una solución a este problema, proporcionando especificaciones abiertas y normas, además de ibre, implementaciones de referencia de código abierto.
