Network-based and client-based operating environments implement computerized systems and techniques for organizing and discovering digital media objects originating from personal digital media sources. The association between a user-selected computer-usable descriptor and a particular digital media object serves as a semantic medium for exchange of information about the digital media object via a network, independent of whether the digital media object is registered with an established digital content sharing service. A user-selected computer-usable descriptor is part of one or more collections of such descriptors that are organized into published data structures having data elements corresponding to particular real-world meanings. Leveraging the consistent associations of computer-usable descriptors with the subject matter of personal digital media content within digital media objects enables the widespread and efficient computerized discovery of relevant digital media objects.
