CBIRDS works are the actual titles of rights holding titles. Each collection holds at least one work.
The work includes all typical properties and relates to data such as rights holders, broadcasts, translated titles and other CMO's unique identifiers. This structure eliminates data redundancy and guarantees referential integrity between collections, works and other entities. Both collections and works can hold unique identifiers of different organizations such as other CMO's but also EIDR, ISAN and IDA.
