truncated dates in ISO 8601

I have looked into the truncated date issue. From wikipedia article on ISO 8601 you find:
"The standard also allows for calendar dates to be written with reduced precision. For example, one may write "1981-04" to mean "1981 April", and one may simply write "1981" to refer to that year or "19" to refer to that century." So if we use the date "1981", we will be compliant to iso 8601 ( latest version : iso 8601:2004). The only issue raised was that the software developer must decide on a way to compare dates of different precision , i.e. is 1981 before or after 1981-02. I did not look into this very deeply but I could find no standard for this. I won't spend any time on this comparison issue right now. Here are a couple of other URLs

iTunes U metadata inadequate

Attached below is the "iTunes U Administrator's Guide" dated June 8, 2007. If you look in the index, the only pages referenced under the term metadata are pages 37 and 38. On page 37 it explains how the word "Album" can be replaced with the word "Course". Likewise "Artist" can be replaced with "Instructor name". This seems to be the extend of its ability to modify metadata which of course does not meet the needs of a library. iTunes_U_AdminGuide.pdf
