Dear colleagues, I was late to join the very interesting and useful discussion. It also took time to read more than 100 posts. Practically all aspects of information sharing and interoperability are considered. I will allow myself to draw your attention to only one point.   In countries/regions where agricultural scientists and consultants have limited ICT skills and access to the Internet, some organizations, at current stage at least, have to take responsibility of collecting data and maintaining, as san_jay sais,  "websites / platforms etc with a minimum level of features that will allow them to handle meta data (and all the associated tit bits) and to communicate among themselves".   Thus the important task is to identify these organizations and build their capacity. In particular, they have to explain researchers, consultants and other stakeholders the benefits of information sharing. They also should contribute to gradual possession of more ICT skills by stakeholders which finally may end up in all necessary pre-processing of data by stakeholders themselves.
