- There is no guideline yet for how the begin date fields might be used.
- There is no guideline yet for how the end date fields might be used.
- Additional Production indicates an artist who introduced new music into the final mix. This can range from merely an overlaid sample to the replacement of nearly the entire recording with music from different sources.
- Associate Production indicates a less experienced producer, who works under the direction of a more experienced producer. 
- Assistant Production indicates a less experienced, or first-time producer, who works under the direction of a more experienced producer.
- Co-Production typically indicates a production team of two or more artists, a song-writing team, a musician and engineer, an engineer and producer, or a producer and artist.
- Executive Production indicates an artist who has been given creative control over the recording and production of the music. They are involved in overall decisions related to the recording, including selecting the studios, selecting the material to record, selecting the producer(s), and selecting the mix(es) which are used. They may also provide financial backing for the project.
- Though it may seem logical that, if a work has two or more producers, they are co-producers, this is incorrect. Producer, Additional Producer, Associate Producer, Co-producer, and Executive Producer are five distinct job titles. If a release has two people credited as "Producer", then they each held the Producer title, not the Co-producer title. The same is true for "additional", "associate", and "executive". Inferred attributes for this relationship type can only result in incorrect relationships. Therefore, credit the relationship only as it appears on the liner, without interpretation.
