I have been looking for a theoretical foundation for the ontology, and I found references of your doctoral thesis, where learning activity structure is described. I wanted to ask if you can send me some information on the description of the structure of the learning activity, for use in the design of the ontology we are creating. We appreciate very much your help, because as far as we know in a very detailed description, which is necessary in the programming process.
