"Most of the documentation is done," Gupta said, adding that around 100 experts had been working on it for the last three years."We have referred to 54 ancient books to research on ayurveda, 35 for unani and 15 for siddha and have documented 50,000 formulae in ayurveda and 24,000 in unani," Gupta said.

He said the task force has created a database of 10 million pages.Under a Rs. 100-million project, the health and family welfare ministry would be preserving all possible details of yoga postures in a multi-media digital library - Traditional Knowledge Digital Library (TKDL).The data will be made available in five international languages, and 11 countries, including the US, Britain, Japan and China, would be able to access it.The task force has found that at least 150 yoga postures that were developed and practiced in India for ages - the system finds mention in Vedic scriptures - have been pirated in the US, Europe and in Japan.It says yoga is a $30 billion industry in the West.
