LIMEFRAME: LearnIng content Management systEm in the FRAmework of MEtacognition

This paper presents a discussion of the current trends in the implementation of Learning Content Management Systems (LCMSs) and provides a working definition of the features that should be provided by such systems. Thus, after discussing a new structure of Learning Objects in the framework of Metacognition to implement significant learning, it shows how an open source Content Management System based on PHP and MySQL (MD-Pro) can be transformed in a LCMS. The system discussed, LIMEFRAME, provides modules for the management of Learning Objects, for their retrieval and indexing via Metadata, and is in line with current standardization approaches with respect to Content Packaging, representation of Metadata and Learning Design. As far as some implementation issues will be solved, LIMEFRAME will be made available to the scientific community for evaluation.
