Feature Request: Support XMP Expression Media namespace / tags

[jottlieb]

Hi,

I'm using Microsoft Expression Media 2 on Mac and tried to remove catalog set metadata from files using ExifTool 8.94.
But that's not possible, because ExifTool does not support Expression Media tags yet.

So I'd like to request support for this tags/namespace. The good thing is, that no further research is neccessary because the tags are the same as in the already supported mediapro namespace, as you can see in the code below (XMP sidecar file generated by Expression Media 2).

               <rdf:li>01_Katalogset</rdf:li>
               <rdf:li>01_Katalogset|Unterset</rdf:li>

         </mediapro:CatalogSets>

Thank you in advance.

Actually, it is more work if these tags already exist.  Now I have to resolve conflicts between the identical tag names.

Is it only the CatalogSets tag that ExpressionMedia uses?  Or does it use the other MediaPro tags as well?

That illustrates why my attempt to extend ExifTool on my own failed

Just seem to be the Catalog Sets. Other fields (like keywords) use other, existing namespaces.

Thank you for your quick response.

[Phil Harvey]

Thanks.

ExifTool 8.97 will support the expressionmedia CatalogSets tag.  This tag will be avoided, so you must specify XMP-expressionmedia:CatalogSets to write it.  (Specifying XMP:CatalogSets will write XMP-mediapro:CatalogSets, and specifying just CatalogSets will write IPTC:CatalogSets.)

Thank you very very very much!

Looking forward to 8.97

[Phil Harvey]

There you go.  Version 8.97 is now available.

After intensive testing (thanks again for your support) I'll just want to make a little note that is might helpful to other users.
I've experienced that in some cases Expresson Media 2 will also embed catalog set metadata in the APP13 segment in JPEGs:

Code Select Expand

JPEG APP13 (60 bytes):
    6fa6: 50 68 6f 74 6f 73 68 6f 70 20 33 2e 30 00 38 42 [Photoshop 3.0.8B]
    6fb6: 49 4d 04 04 00 00 00 00 00 22 1c 01 00 00 02 00 [IM......."......]
    6fc6: 04 1c 01 5a 00 03 1b 25 47 1c 02 00 00 02 00 04 [...Z...%G.......]
    6fd6: 1c 02 ff 00 07 54 65 73 74 73 65 74             [.....Testset]

That means that even after removing the catalog set metadata in XMP, Expression Media 2 is still able to interpret the remaining information.
I'm actually solving this problem by treating JPEG files with the Perl module Image:MetaData::JPEG afterwards.

[Phil Harvey]

You don't need to use Image::Metadata::JPEG to edit the APP13 information.  Just specify IPTC:CatalogSets with ExifTool.

Well....where's the facepalm emoticon? Seems I was a little bit blind.

So thank you very much again.
