ODS Calendar WebID Protocol Sharing

The following HOWTO walks you through the process of setting the following:

  • Virtuoso instance as Certificate Authority (CA) for signing X.509 certificates
  • HTTPS listeners for an OpenLink Data Spaces (ODS) instance
  • Generation and export of Private Keys and X.509 certificates (that include your Person WebID) to your Browser
  • Persistence of Certificate's Public Key to your ODS profile (FOAF or XRDS based Structured Profile)
  • Use of the WebID Protocol option for ODS-Calendar Access Control Lists (ACLs) when providing controlled shared access to Tasks/Events.
