XML for engagement stats/media kit?

[Radu]

Hi,

In general one can create indeed a custom XML Schema to express the content that they want to have encoded. Maybe you can ask an AI tool to create an XML schema for you based on your expressed needs. Oxygen also has an AI Positron add-on which may be helpful for this:

DITA XML was created in general for technical documentation, it has a specific vocabulary, you can give it a try and see how you could use it to encode your data, with DITA XML at least you would have publishing to HTML, PDF for the content.
