Electronic Research Data Archive (ERDA) and SCIENCE HPC Center
ERDA (erda.ku.dk, erda.dk, sid.erda.dk) is the university's research data archive, operated by the SCIENCE HPC Center at the Faculty of Science and skinned erda-ucph-science. UCPH users authenticate through id.ku.dk; external collaborators through oidc.erda.dk and cert.erda.dk. The archive exposes data over WebDAVS, SFTP and FTPS rather than a documented HTTP API, and no OpenAPI or /.well-known descriptor was found on any ERDA host. The associated SCIENCE HPC Center at hpc.ku.dk documents SLURM, Lustre, MPI, compiler and VGL access as web pages. Recorded as a real institution-operated research-computing surface with no machine-readable contract.
