Each publication in structural biology is derived from a series of processing steps, using data from structural experiments which in turn use samples produced by “wet” laboratory operations. For purposes of data reuse and reproducibility of results, it is desirable to record this whole chain of custody. Current practice falls far short of this. (See project deliverable D7.9.) The W3C standard PROV-O is designed to support the recording and sharing of such information. We have developed mechanisms for automatically saving this information, storing it, and viewing it. Once the necessary take up is achieved, so that provenance data is recorded, this will allow a user looking at structural results to see the processing steps and, back along the chain of custody, the experimental data.
