The document discusses integrating ORCID identifiers with HUBzero, an open-source platform for online scientific collaboration and research. It describes three use cases for the integration: 1) allowing new users to register with HUBzero and create an associated ORCID identifier, 2) linking a user's HUBzero profile to their ORCID profile, and 3) including a user's ORCID identifier in metadata when they publish datasets through HUBzero. A prototype has been implemented and tested with three Hubs (nanoHUB, PURR, and HABRI Central), with plans to contribute the integration code to the next HUBzero software release.
