what is selene project
What is SeLeNe Project
  • An approach to provide a SELF e-learning network in order to support geographically distributed and highly heterogeneous learners.
  • “Trying” to facilitate the formation of learning communities that require world-wide discovery and assimilate of knowledge by elaborating new educational tools.

selene objectives
SeLeNe Objectives
  • Conduct a study of on-line educational resources and metadata, and of learners\' and instructors\' expectations of e-Learning systems.
  • Identify technologies for syndication and personalisation of educational resources.
  • Identify technologies for managing evolving RDF description bases, and design the high-level system architecture of a Self e-Learning Network.

what is e learning object
What is e-learning object
  • It describes a broad category of digital assets that can be used for learning, training, or knowledge development.
  • A learning object can be as small as a paragraph of text and as large as a 3 month online course.

what is lom
What is LOM
  • Creation of well structured descriptions of learning resources
  • Sharing of descriptions of learning resources between resource discovery systems
  • Tailoring of the resource descriptions to suit the specialised needs of a community
