Concept, Resource, Order, Product (CROP) is a reference architecture for
adaptive Learning Objects owned by Semantic Learning Services developed by
the second author. According to CROP, composite Objects are essentially
recursive, and adaptively is an emergent property of Learning Service
communication and collaboration. CROP is formally represented as an OWL
ontology consisting of the framework's concepts and its definitions.
In this report we present a free, open-source, java-based graphical editor
that populates CROP ontology with instances of Learning Objects at runtime
through a (guided) graph-like interface. While developing this tool we
proceeded to some adjustments on CROP ontology and further clarifications
on the architecture. Our ultimate vision is to design Semantic Learning
Domains where repositories of such ontologies exist and Services
collaborate for delivering adaptive Objects to custom Learners’ needs.
