Orthanc 1.12.0 has just been released! This new major release notably introduces supports for labels, which can be used to efficiently index #DICOM resources according to user-defined criteria.

Labels can notably be used as a primitive to build multitenant Orthanc deployments (a sample multitenant DICOM server is provided in the Orthanc distribution), or to support artificial intelligence workflow by cleanly separating training and testing sets. https://book.orthanc-server.com/faq/features.html#labels
