Mp3 tags are called id3, id3v2 etc. What do you call the tags in mp4 (e.g. itunes tags)?

All tags are stored in a MP4 container file (MPEG 4 Part 14) and the tag frames are known as atoms.

The standard MPEG 4 spec uses "meta" atoms to store metadata, while iTunes uses "udf8" atoms to write tags in UDF-8.
