The document discusses sharing educational resources and learning objects openly on the internet. It proposes representing instructional design methods and theories using ontologies to allow searching for and comparing learning designs based on the instructional approaches used. Recording more details about learning designs could help link theoretical approaches to practical outcomes, inform future design work, and enable more rigorous comparisons between different instructional techniques. Representing instructional design processes formally may help move the field towards more data-driven, evidence-based practices.
