TKDL- A safeguard for Indian traditional knowledge
by Nirupa Sen
Excerpted from: Current Science 82 (9): 1070-71.
India has woken up to the task of protecting her traditional knowledge from
patent bio-piracy. The trigger was the successful revoking by the Council
of Scientific and Industrial Research (CSIR) of patents filed on turmeric,
neem and basmati. This success set the tarmac from which the new initiative
called the 'Traditional Knowledge Digital Library (TKDL)' is getting ready
for flight. The first phase of TKDL on ayurveda is marked for completion in
October this year. For bringing out a TKDL on ayurveda, a Memorandum of Understanding
was signed on 6 June 2001 between the National Institute of Science Communication
(NISCOM), New Delhi and the Department of Indian Systems of Medicine and Homeopathy
(ISM&H), Ministry of Health and Family Welfare.
When compiled, TKDL would have documented the traditional knowledge available
in the public domain in a digitized format. Starting with the existing literature
in ayurveda, it would later cover unani, siddha, naturopathy, homeopathy and
folklore medicine. In the first phase, a 'Traditional Knowledge Resource Classification
(TKRC)' is being prepared for 2147 medicinal plants. The content of TKDL would
initially consist of about 35,000 'slokas' (verses) from ayurveda. These slokas
gleaned from 14 ancient texts and recognized books would be digitally transcribed
into a readable form and made available both in Indian and foreign languages.
The methodology adopted in setting up TKDL is explained below. TKDL would
help patent examiners the world over to have a ready reference to Indian traditional
knowledge, while granting patents in such domains. The project cost for TKDL
is about Rs.1.18 crore. TKDL is an effort that brings together the Department
of ISM&H, CSIR and the Ministry of Commerce and Industry. :
At the inauguration of TKDL in New-Delhi on 26 March 2002, the Minister of
Health and Family Welfare, C. P. Thakur emphasized that TKDL would play 'a
crucial role not only in documenting our precious heritage in the area of
traditional health-care systems, but also in preventing bio-piracy and un-
- scrupulous patenting of indigenous herbal medicinal formulations'. He stated
that in the prevailing era of globalization, only the efficient would survive.
Therefore we need to protect ourselves from theft of traditional knowledge.
The TKDL, he added, could also serve as a useful reference point for research
workers. The awareness that such a library would create might help the cause
of preventing extinction of rare species. Awareness generated could be helpful
in the propagation of such species in conjunction with farmers, Thakur felt.
R. A. Mashelkar, Director General of CSIR, while speaking on this occasion
pointed out that the global market for herbal/traditional medicines is US
$ 60 billion, with an annual growth rate of 5- 15%. In this, China's share
is about US $ 7-8 billion and India's US $ 400- 500 million. He also referred
to a TKDL Task Force study of the US Patent and Trade Mark Office (USPTO)
database conducted in March 2000. The study showed that out of 4896 references
on 90 medicinal plants mentioned in the USPTO database, 80% of these references
was on seven medicinal plants of Indian origin:
Kumari, 'Mustaka, Tamraparna, Garjara, Atasi, Jambira, Kharbuja. The findings
revealed that out of the 762 patents on medicinal plants studied, 360 of them
could be characterized as traditional.
There has been international acceptance of TKDL, Recently, the World Intellectual
Property Organization (WIPO) constituted a group of members from USPTO, China,
Japan, European Patent Office and India for discussing the findings of the
TKDL Task Force. The group presented their views at the International Patent
Classification (IPC) Union meeting in February this year. The outcome is to
create a new sub-class for TKRC in IPC and link TKRC with ayurveda. India's
TKDL database has also been selected for a pilot study by 170 member states
of WIPO. India presently is not a member of the IPC Union.
When completed, TKDL would help patent examiners for easy retrieval of traditional
knowledge-related information, thus avoiding the possibility of granting patents
to unoriginal inventions. Further, a review process of patents already granted
in light of the TKDL database would help in cancellation of some patents.
Methodology used for TKDL
Slokas from ayurvedic texts are first identified. Each sloka is read and
converted into structured language using Traditional Knowledge Resource Classification
(TKRC). TKRC is innovative in itself. The TKRC classification has been evolved
for about 5000 subgroups as against one group in file International Patent
Classification (IPC) for traditional knowledge. The TKDL portal would be based
on XML standards and would be platform-independent. The codes for each sloka
are fed into a data entry screen and also saved on the database. Computer-savvy
ayurveda experts carry out the data entry. These are then decoded in different
languages. The ayurvedic formulations can be presently decoded in English,
French, German, Hindi, Japanese and Spanish. In future, it would be available
in 20 foreign languages and all Indian languages. The decoded format of the
formulation is easy to read and understand, even by the layman.
The web version of TKDL would include a web-based search interface. This
would provide for a full text search and retrieval of traditional knowledge
information on IPC and keywords in multiple languages. TKRC would be an integral
part of TKDL, and would provide a background on ayurvedic concepts, definitions
and scientific basis of Indian systems of medicine. In addition, it would
carry information on practitioners, hospitals and dispensaries. There are
several search features incorporated in the format.
According to V. K. Gupta, Director of National Institute of Science Communication,
the TKDL software developed in-house does not do transliteration but it does
smart translation. Once abstracted, data from the slokas are converted into
several languages using Unicode meta data methodology. The software developed
can perform smart translation of botanical names and ayurvedic descriptions
from traditional terminology into modern terminology. Examples of this are
'Kumari' to 'Aloe Vera', or 'Mussorika' to 'small pox', etc.
