Contact Info of photographer

How do I enter the contact information under Author in the IPTC tab. When attempting to enter, properly placed commas in the field creates a block of text and information is not logical for the field.

According to the documentation, IPTC:Contact is defined as follows:

Repeatable, maximum of 128 octets, consisting of graphic characters plus spaces.
Identifies the person or organisation which can provide further background information on the objectdata.

The value of this tag should be a list of strings of 128 characters. That is why MetaImage displays the tag as a list using standard mac components. Unfortunately, Mac uses commas to separate strings. That is why you cannot add a comma. I will add an option to change the default separator.

Thanks for the feedback.
