Over the past three years, the PASOA project has investigated how to determine the provenance of data, i.e. how data came to be produced. Provenance is important in science, where the rigour of experiments gives value to their results, in art, where the authenticity of an object is checked via records of ownership, and in many other domains. The increasing use of large scale distributed systems to process information across organisations, such as in Grid systems, makes the problem of determining provenance both more difficult and more pressing. In this presentation, I will give an overview of provenance in computer systems and the technologies we have developed to aid users in querying for it.
