Resumen:
There has been lately much effort put on the creation of
digital libraries containing antique documents, in order to preserve our
cultural heritage and provide a broader access to them, but they are
usually isolated one from another. This work presents a system, based
on the use of XML trees, to federate three existing digital libraries that
contain documents from the Spanish Golden Age (16th-18th centuries).
This federation offers very valuable advantages to a wide community of
researchers, who will be able to access (at present time, three) databases
of historic documents through a unique entry point.
