The base of metadata is LOM IEEE specification of learning objects: LOM – Learning Object Metadata (60 items) Data elements describe a learning object and are grouped into categories. The Base Scheme (clause 6) consists of nine such categories: 1. The General category groups the general information that describes the learning object as a whole. 2.  The Lifecycle category groups the features related to the history and current state of this learning object and those who have affected this learning object during its evolution. 3.   The Meta-metadata category groups information about this metadata record itself (rather than the learning object that this record describes) . 4.   The Technical category groups the technical requirements and characteristics of the learning object. 5.  The Educational category groups the educational and pedagogic characteristics of the learning object. 6. The Rights category groups the intellectual property rights and conditions of use for the learning object. 7. The Relation category groups features that define the relationship between this learning object and other targeted learning objects. 8. The Annotation category provides comments on the educational use of the learning object and information on when and by whom the comments were created. 9. The Classification category describes where this learning object falls within a particular classification system. Collectively, these categories form the Base Scheme. The last category, Classification, enables an end user to classify a learning object according to arbitrary classification structures. As any classification can be referenced, this category provides for a simple extension mechanism. The base of metadata is LOM Sam Joachim: Current trends in e-learning … (Ohrid) 9 categories MuSoft extracts 5 categories 19 items Example: Requirements engineering (later) Zagreb, 6.–11.09.2004; U.
