The following are predicates in use for the different models defined in Fedora for Avalon, versions 6 and higher.
MasterFile Class Predicates

Encoding Class Predicates
...
| quality | ebucore:encodingLevel | http://www.ebu.ch/metadata/ontologies/ebucore/ebucore#encodingLevel |

EBUCore only supplies a single property for bitrate and for codec, so the following properties apply to video and keep audio properties as Avalon-specific:
...
| videoCodec | ebucore:hasCodec | http://www.ebu.ch/metadata/ontologies/ebucore/ebucore#hasCodecvideoBitrate |
| ebucore:bitRate | http://www.ebu.ch/metadata/ontologies/ebucore/ebucore#bitRate |
Properties that do not have a mapping to an external ontology:
