APNA OPUS ('Our Own' OPUS) is a tool designed to facilitate collaborative creation and peer to peer sharing of media data for communities gathered together on a local or enclosed network, as well as on the internet. APNA OPUS works for any context where people want to collaborate on creative media projects, be they local - in one class room or media lab, in a cluster of class rooms or media labs, or global - all over the internet.

Any group of users on computers that use a local area network can begin to use APNA OPUS to create their own peer to peer network, share and exchange files, as well as create collaborative media works. This makes the sharing and collaborative creation of cultural material possible even when there is no access to the internet, or when the scarcity of bandwidth or low-speed web connectivity make high volume file sharing and transfer a difficult or near impossible task.

From OPUS to APNA OPUS
APNA OPUS is a development of OPUS (Open Platform for Unlimited Signification) a php/mysql based took which was created in 2001.

The APNA OPUS pilot was developed and designed in close association with young media practitioners in the Cybermohalla Project Labs of the Sarai Programme, and its first implementation will also be carried out by Cybermohalla practitioners in free software equipped Media Labs located in working class neighbourhoods of Delhi. APNA OPUS is specifically designed to address the desire for creativity in culturally rich contexts, with a strong ethos of shared and collaborative work and especially in situations of technological or infrastructural scarcity. This makes it ideal as a platform for use in schools and educational institutions, youth groups, artists and media practitioners collectives, research networks, cultural organizations and affinity groups in those parts of the world where access to computers does not yet automatically translate into access to high bandwidth internet connectivity.

APNA OPUS  emerges from a process of collaboration between Raqs Media Collective, Silvan Zurbrügg (a programmer based in Zurich) and Victoria Donkersloot (an interface designer based in Rotterdam) initiated at Sarai in 2004-2005. APNA OPUS is currently accessible at http://apnaopus.var.cc.
Apna Opus uses BitTorrent, Python, sqlite database (tracker) and xml (for Podcasts & RSS).
