A Generic Adaptivity Element education? adaptivity? adaptivitytype* name= ref= ? langstring*
Example Visual Disability Database concepts
Best Practice Lists for Adaptivitytype Names Compatibility of adaptivity information Acceptance through comprehensive list Hierarchical structure for shared vocabularies
Vocabularies Vocabulary used within adaptivitytype content depends on subject and on pedagogical models Common vocabulary is a prerequisite for interoperability Possibility to use specialised vocabularies
An Extended Adaptivity Element adaptivitytype* name= ref= ? set? type=“one-or-more“|“all“|... set* candidate* langstring*

Summary The suggested generic metadata element for describing adaptive learning objects is: suitable for many different types and mechanisms of adaptivity applicable for structured information flexible with respect to vocabularies
