Standards and specifications widely accepted and used lay the foundations to enable and facilitate the interoperability among systems, and the software maintenance and reuse, especially within the scope of learning objects’ search systems. One of these standards is the SQI (Standard Query Interface) specification by the European Committee for Standardization in which many search systems, including public ones, are based. This paper analyzes the degree of compliance with this specification by a significant number of learning objects repositories. |
