Object Creation Thread
| Excerpt |
|---|
When new content is uploaded to DfR (via DuraCloud), it is uploaded as a bytestream having a limited amount of metadata in itself. Also, DuraCloud operates with semantics appropriate to a bytestream, a desirable characteristic since this creates a logical separation of concerns between storage-like containers and containers that perform other functions. In DfR, a key container/service family is the Fedora Repository. It is able to support a richer set of semantics for marking up and relating bytestreams to other content. To do this, however, Fedora Digital Objects, using the FOXML schema, must be created encapsulating the uploaded bytestreams (stored in DuraCloud). |
