Terms of service

By using this service, you provide us with information that you wish to store on our server (referred to as Stored Data). You are responsible to control the visibility of your information (i.e. provenance documents) on the server. If you mark your documents "public", you agree for the documents to be made public by the service. In any case, you always retain full ownership of your Stored Data and will be able to remove any Stored Data you no longer wish to be stored on our server.

Since the service is provided via JANET, it is bound by JANET’s Acceptable Use Policy. We reserve the right to remove entries that are deemed inappropriate. In addition, we make no guarantee on the continued availability of the service.

The services will be regularly backed up and upgraded. However, due to limited resources, we offer no guarantee of data safety or the continuation of the services. Please refer the Information Sheet for more information.


During the registration, we ask for your email address so that you can request a password reset when required. We will never reveal your email address to a third party or use it for any other purpose.

In addition, this service collects and stores the following information (referred to as Collected Data):

  • Web access log.
  • Metrics of provenance data posted to the services (e.g. size, statistics and topology measures) inspired by our Provenance Analytics Paper.
  • Validation reports that describe places where provenance is invalid, incomplete or incorrect.
  • Digest of provenance data posted to the services (e.g. signature of provenance and timestamps).
  • Anonymous summaries of provenance data, inspired by our GAM'15 paper.

In addition, further data is collected indirectly by third-party "web analytics" services such as Google Analytics, New Relic, Sentry, and User Voice.

If you change your mind, you can remove your Stored Data from our services at any time and/or request your account to be deleted. Collected Data, however, are stored in an anonymised format and, hence, we provide no mechanism by which Collected Data can be erased.

The collection and storage of the above data has been approved by the Ethics Committee at King's College (REF: LRS-16/17-4786 - Study title: Public Provenance Services). If you have any questions, please see the Information Sheet for more information.
