A Proposal to Improve the Simple Query Interface (SQI) of Learning Objects Repositories

This paper proposes to improve the Simple Query Interface (SQI), designed to query learning object repositories, modifying a few existing methods to generate new ones. Replacement is not intended, instead, our proposal is to create new methods that incorporate several enhancements in order to enable compatibility with currently compliant systems that use the old methods. Besides, new methods are also proposed aiming at improving the interface as well as at providing compatibility with the Simple Publishing Querying (SPI) specification. With these improvements SQI specification will perform its task in a more structured and efficient manner.
