Default defined APE tag keys/frames


Please forgive me for my ignorance, I might be completely off here, but since Frank Klemm seemed to be the only one hosting some complete information about APE tags I hope you don't mind me contacting you guy's for some questions about the tags [1].

I send this e-mail to Frank directly as well but I did not get a reply and after I send the e-mail, the website was taken down for some reason. If you know a mirror of the mentioned page, please let me know.

To clear things up a bit first: where did the APE tag system originated from? I'm a bit confused and not a 100% sure because the name would imply that it originated from the Monkey's Audio format, though that site doesn't realy contain any info about it.

I'm currently working on a tag frame reference of the different tag sets (ID3, APE, Vorbis, Matroska, etc.) and because of that I've got several questions about the defined APE tag keys [2].

I'm having trouble creating an accurate mapping of the following tags because the exact definition isn't exactly clear to me.

Does the location of the file need to be stored in the tags of the
same file? What exact type of location are we talking about since it
has to be a URL?
Just any kind of catalog id/number of any kind/type of catalog?
Wouldn't the type of catalog (e.g. by which company or website
( or something)) need to be known?
I don't get this one, what is it that you want to have stored in this
tag? Is it like the WWWAUDIOSOURCE (WOAS) frame in ID3 [3]? WOAS is
used to point to the official webpage for the source of the audio
file; e.g. if the audio is "extracted" from a movie. This doesn't
explain the Source Media Number/Total Media Number and Source Time
Indexes for quick access? Quick access of what? Can this key be
compared to the MPEGLOOKUP (MLLT) frame in ID3 [4]? This one is used
for a MPEG location lookup table to increase performance and accuracy
of jumps within an audio file. Or am I completely off here? :-)
Location to what kind of related info?
Abstract as in a description of the content? If so, why does it need
to be a link?

Thank you in advance for your time and help.
