I have been thinking about this for sometime, but today I saw this -
http://www.deccanherald.com/content/490282/india-blocks-colgate-patents-spices.html - and I was again tempted to do something about it.
Try searching for something like "basil". you get comprehensive formulae for ancient indian recipes, methods of application,etc
do note that to determine these links are useful from the site itself took me an hour !
I wonder if we can access the raw data, ETL it, index it in elasticsearch and give raw access to Elasticsearch for people. I'm pretty sure it would be more useful than what we have right now ! Some of the references include page numbers to ancient indian books. Maybe it is possible to upload these books to Amazon S3 .. I'm pretty sure they are copyright free.
