Custom scheme XMP

[Phil Harvey]

Any idea? 

Yes:

The property 'dc:mytest' is not defined in schema 'Dublin Core Schema'.

Hahaha, could I specify the schema that I want to use in the configuration file for exiftool to take it? for example: http://ns.adobe.com/pdfx/1.3/

[Phil Harvey]

You can try, but your other validator didn't like custom tags in pdfx.

In the config, how could you specify the schema, do you have an example that you can share with me please?

[Phil Harvey]

I think you're missing the point.  The schemas are defined by the various standards that are recognized by your validator.  They aren't something that is written in the file.

Honestly, I thought that in the namespace it was specified in the config file:

https://www.pdflib.com/pdf-knowledge-base/xmp/xmp-in-pdfa/

%Image::ExifTool::UserDefined::ns_1 = (
    GROUPS        => { 0 => 'XMP', 1 => 'XMP-ns_1', 2 => 'Image' },
    NAMESPACE     => { 'ns_1' => 'http://www.aiim.org/pdfa/ns/schema#'; },
    WRITABLE      => 'string',
    tag_one => { },
    tag_two => { },
    tag_three => { },
    pumpkinpie => { },
);

%Image::ExifTool::UserDefined::ns_2 = (
    GROUPS        => { 0 => 'XMP', 1 => 'XMP-ns_2', 2 => 'Image' },
    NAMESPACE     => { 'ns_2' => 'http://www.aiim.org/pdfa/ns/schema#'; },
    WRITABLE      => 'string',
    abc_one => { },
    donuts => { },
    abc_two => { },
    spaceship => { },
    unknown => { },
);

# The %Image::ExifTool::UserDefined hash defines new tags to be added
# to existing tables.
%Image::ExifTool::UserDefined = (
    # new XMP namespaces (ie. XXX) must be added to the Main XMP table:
    'Image::ExifTool::XMP::Main' => {
        ns_1 => {
            SubDirectory => {
                TagTable => 'Image::ExifTool::UserDefined::ns_1',
            },
        },
        ns_2 => {
            SubDirectory => {
                TagTable => 'Image::ExifTool::UserDefined::ns_2',
            },
        },
    },
);

1;  #end

Could you clarify this, please?

The problem is that your validator only recognizes pre-defined schemas.
