The Learning Object Vocabulary (LOV) was generalized from sources in instructional design and technology, learning theories and practices, and conventional library classification and thesauri. This version has the following main categories of learning models, learning objectives, and learning objects. Sources used in creating this ontology include DDC, ERIC Thesaurus, and research publications in learning objects and theories found from the leads provided by http://carbon.cudenver.edu/~mryder/itc_data/idmodels.html (University of Colorado at Denver, School of Education) and http://www.uwm.edu/Dept/CIE/AOP/LO_what.htm (University of Wisconsin at Milwaukee, Center for International Education).
