- The introduction of new DCO Portal features required users to log into different subsystems, including the DCO Community Portal (based on Drupal Commons ) and the DCO Data Portal (based on the VIVO semantic knowledge management platform). In order to facilitate the use of multiple systems and improve the user experience, DCO Data Science implemented single sign-on using the Shibboleth federated identity solution. User information is stored in the Apache Directory Server , an LDAP-enabled platform.
