Ashampoo XMP Core v0.2 is available 🥳

This library is a port of Adobe's XMP SDK to Kotlin Multiplatform by Ashampoo.

The new release adds some convenience functions to XMPMeta for commonly used properties.

For example you can now use XMPMeta.getOrientation() as a shortcut to XMPMeta.getPropertyInteger(XMPConst.NS_TIFF, "Orientation").

Also XMPMeta.getKeywords() and XMPMeta.setKeywords(keywords: Set<String>) might save you some time.

Check it out:

Would be nice for the Readme to mention what it is. It says it’s a port of some other library by Adobe, but for people who never used it, it’s unclear what this does. (Nowhere does it say what is “XMP”)

@Marcin Wisniowski Thank you for your feedback. I will see to add a paragraph that explains XMP.

Maybe a short description and a link to https://en.wikipedia.org/wiki/Extensible_Metadata_Platform

Basically it’s a XML format that defines image metadata which was invented by Adobe to replace EXIF & IPTC. But as always when you invent a new format to replace another it’s just one format more in the end. So today image metadata consists of EXIF (TIFF like, very old), IPTC (known as Photoshop Metadata) & XMP

Take a look at an example XMP file:

Thank you, that makes perfect sense now!
