INDIA A CULTURAL PANGEA

Early 18nth Century antique map of the region from India, Tibet and China to the Gulf of Siam and the Gulf of Bengal, showing the travels of Sir William Methold to the Diamond mines of Golconda, the first European to visit the Diamond mines.

India is a cultural Pangea

across centuries of

civilization, colonization

and globalization

TANGIBLE CULTURAL HERITAGE

India has an estimated 5 million ancient manuscripts - written on palm leaf, birch bark, metal, cloth, even gold and silver. National Mission for Manuscripts was initiated in 2003 in a conservation effort – though much of the work is unfinished.

MANUSCRIPTS

TEMPLES

Temples have been a centre for India’s religious, cultural, economic and social life for thousands of years. Noted for their architecture, sculptures and murals that decorate their outer and inner walls - temples form a unique cultural identity for the Indian civilization built, destroyed and reconstructed across centuries.

TANGIBLE CULTURAL HERITAGE

DANCE

INTANGIBLE CULTURAL HERITAGE

The principles of Indian Classical dance is derived from ‘Natya Shastra’ by Bharat Muni. He traces its origin from lord Bramha & dictated that Lord Bramha created a fifth veda known as ‘Natyaveda’, representing the essence of four existing Vedas. Pathya (words) were taken from Rigveda, Abhinaya (gestures) from Yajurveda, Geet (music) from Samaveda, Rasa (emotions) from Atharvaveda.

Three main components form the basis of these dances: Natya: the dramatic element of the dance Nritta: pure dance, in which the rhythms and phrases of the music are reflected via body gestures Nritya:the portrayal of mood through facial expression, hand gesture, and position of the legs & feet

DIGITAL HERITAGE PRESERVATION EFFORTS

INDIAN HERITAGE IN DIGITAL SPACE RESEARCH

IHDS programme objectives: 1. To initiate and nurture research in the frontier areas of digital heritage with specific reference to problems of Indian context. 2. To create a crowd-sourcing framework for building digital collections of heritage resources through participation of the public in general. 3. To create a mechanism to store, curate and distribute multi-media digital resources and assets for unrestricted access to support cross-disciplinary research in Indian heritage.

• Investigation of the basic requirements related to digital heritage archiving and usage: Through collaboration between the culture and the technology communities; identify the nature and form of heritage that is most suitable for digital capture, storage and use.

• Data collection and archiving: Create through a community based effort data, sources, standards, schemas as well as the necessary technology to enable the storage and processing of relevant media.

The project focuses on the art, architecture and cultural legacy of the world heritage site of Hampi in Karnataka, the medieval capital of the Vijayanagara dynasty.

THE MAKING OF HAMPI

• Research and creation of tools and technologies

• User experience: create compelling and holistic end user experiences that highlight the historical and artistic significance of various monuments and other types of heritage content.

The project focuses on the art, architecture and cultural legacy of the world heritage site of Hampi in Karnataka, the medieval capital of the Vijayanagara dynasty.

Hand-gestures, body movements and facial

expressions express a natural language keyword or

phrase in Indian classical dance.

Recognition of a hand-gesture or facial expression

in an image or a video can lead to the discovery of

the semantic concept defined by the keyword/s

expressed, or could lead to the discovery of high

level concepts like a mood, words of a poem or

portion of a mythological story. This could generate

new semantic forms from the existing ones.
