What's the best way to work with PDFs in Capacities?

While you can upload, view, link and embed PDFs in Capacities, the PDF object type itself cannot be customized with additional properties. If you want to add metadata to a PDF like author, year, etc., a good approach is to create a separate object type like "Sources". You can define any custom properties you need there. Then simply embed or link the relevant PDF into your Sources object. This has the added benefit of allowing you to collect various media related to a source in one place - PDFs, websites, images and more.
