Data Type
Define what data type the field should be. Your choices are:
Text:
This is the data type used earlier for almost all IPTC fields. Selecting this data type means
that any type of text can be entered into the field. You must also choose the maximum
number of characters that can be entered into this field.
If desired, you can use the Regular expression field to define rules governing the type of
text that can be entered into the field. This can for example be used to make sure that the text
entered is a valid e-mail address. Test the regular expression in the field below by entering
something you think the regular expression should accept. The test field will be green if the
text you entered is accepted and red if the text is not accepted.
Integer: Only integers (“whole numbers”) can be entered into the field if this is the data type selected.
If desired, you can also enter a minimum and/or maximum number.
Real:
Only numbers (integers or decimals) can be entered into the field if this is the data type
selected. If desired, you can also enter a minimum and/or maximum number.
Date:
Only dates can be entered into the field if this is the data type selected. The date format is
defined by your system settings.
Boolean: Only the two values True or False can be entered into the field if this is the data type selected.
Storage (XMP) Page
On this page you find information about where in the XMP file the field should be saved. If you are
editing a previously created metadata field, you are not allowed to edit these properties and they are all
disabled. If you created a new metadata field, these properties must be entered.
Field name
Enter a name for the field. This name is only used internally in the XML file, and is not visible anywhere
else. The Display name found on the Field Id page is the name that will be displayed in text editors,
etc. Use only letters (upper or lower case) and numbers for the Field name. The Field name may not
begin with a number or contain spaces.
Namespace
Choose the namespace that this new field should be a part of. Available namespaces appear in the dropdown list. If no namespaces are available in the drop-down list you must first add a new namespace
before you can add a new field.
