Are the URLs for the ns.exiftool.ca namespaces no longer valid? Were they ever?

When I use the -X option the output lists all of the namespaces, but none of the URLs work.

For example:
xmlns:XMP-dc='http://ns.exiftool.ca/XMP/XMP-dc/1.0/'
xmlns:XMP-dwc='http://ns.exiftool.ca/XMP/XMP-dwc/1.0/'
xmlns:XMP-xmp='http://ns.exiftool.ca/XMP/XMP-xmp/1.0/'

Thanks,

Rick

Hi Rick,

Those aren't URL's, they are URI's.  URI's don't necessarily point to a valid web page.  Those URI's never existed as web pages (and most URI's don't).

...where DIR is the name of a directory/folder containing the images.  On Mac/Linux/PowerShell, use single quotes (') instead of double quotes (") around arguments containing a dollar sign ($).

Ah, yes of course. Thank you Phil. Are the resources/namespaces defined anywhere?

Hi Rick,

They are not defined anywhere, but the URI's are simply constructed from the family 0&1 group names of the tags:

http://ns.exiftool.ca/GROUP0/GROUP1/1.0/
