Thank you. That's a good start.
Part of my uncertainty is that, looking at Index Cards for the existing issues, I'm not sure what information is supplied by the uploader, and what is added at the site by people/software.
The Index Card has a field called Title; the Upload page has a field labeled Title. But they don't contain the same information. The Index Card Title is just the name of the comic book and is the same for each issue. The Upload page Title is Name of the comic and number. I suggested "Ribtickler #4", you said "Ribtickler 4". Is "#" not allowed in the Title field? That is not "self-explanatory".
The next field in the Index Card is the issue Date. The Upload page doesn't have a Date field. Does someone on site look at the uploaded pages and determine what the Date field should be? Or is that something I should supply? If so, where? In the Description? As part of the file name? And if I do supply it, should I just use the first month if the date in the comic specifies multiple months?
For example, Ribtickler was a bi-monthly comic. When Ribtickler 5 was published, it was stated to be the "Nov-Dec 1946" issue. But the Index Card merely states "Nov 1946". I presume for quarterly comics (I'm not taking the time to look for examples) "Summer","Winter", etc. are listed that way.
You state the file format should be zip or cbz. I don't expect you to tell me how to create those types of files; that's just general computer knowledge. I do notice, looking at the Index Cards, that there are also files of type cbr and rar (Ribtickler 7).
Are there any "gotchas" about the File Name? E.g. I frequently use File Names with words separated by spaces; in the few I looked at here, the words are separated with "_" or ""-". Would embedded spaces in the File Name cause a problem?
And I presume that the Upload page Description field gets propagated into the Index Card Notes field. Which implies that the Date information is NOT put in the Description field. Ribtickler 5 has Notes that say "Complete! A freddyfly original production!". That came from the Description field, correct?
I don't think I would use that. Interesting info about the comic book I would usually add to the GCD record, since I see that Additional Information at the bottom of the screen is propagated from the GCD. I would probably only use the Description field for something that pertained to this particular copy; e.g. if I was uploading a comic with missing pages - I would say which ones were missing.
I have added all the info I know about Ribtickler #4 on the GCD site, which will be approved before I get the scans done.
