The video commons

The commons is the collected body of creative artwork and knowledge shared and made freely available for others to use. Video commons is the unchartered part of the commons that concerns animations, films, and other videos. Preliminary research shows there are around 19 million videos freely available in the video commons.

Mapping the commons

We map the video commons by creating and publishing an index of freely available videos. In the process op mapping, we identify provenance and license information of these videos. By use of our index, this information becomes easily accessible and easy to use.

Fingerprinting algorithms

Supporting the video commons

We develop algorithms for video fingerprinting and support the process of standardisation of fingerprint algorithms and formats. By adding the fingerprints to our index of the video commons, we create a whitelist of known openly licensed videos. This whitelist can inform and provide clarity on videos in the commons.

We have indexed about 70.000 videos in a whitelist that allows full metadata search, a means to search for a hash and similar hashes (up to 10 bits different), and allow the uploading of your own video’s to create a hash.

Standardising Persistent Reproducible Identifiers 

A strong commons needs a way to reconnect media to provenance information. Often when files are shared outside the original publication context its links to the original creator are lost. A call for standardising shared persistent reproducible identfiers, a meeting of minds, and a white paper on persistent reproducible identifiers we work towards a stronger commons and a stronger Internet.
