I think your article brings to light the proper path to getting information out to DC in a very good way. I live presently in a country that has a good database system commonly called Lanl here. But all the Developing Countries can benefit from their own centralized system themselves. In the past, till I recently became Chief Editor of the Journal of Advanced Propulsion Methods, I had done educational websites online to inform and educate people on the progress of modern Science. I have always strived to see that these websites were open to all the search engines worldwide for a very strong reason. I believe Science belongs to all the Planet and that the key to progress towards world peace and a better Planet in general is seeing that all Countires have an equal chance to develope properly and build a decent infrastructure. One key to that structure is Scientific knowledge. Such a system as you propose for DC's in part of the way to make sure that happens.
