> A plain text file (meta.md) can store optional metadata and is readable simply by opening it

To me, "readable" is not enough. Entering this data-augmentation text is time consuming: it should be as easy as possible. Including "augmenting" in batches (for this photo and that one and these 200 others).

Markdown in particular is not it - augmenting is not about presentation but about something like unstructured input of structured data. Or unstructured input of data which is systematic enough that it can be exploited by structured data retrieval. For example, "my finished art" or "my clothing inspiration" even when there is not strictly one way that these are tagged (yet).

To me, this means that super-efficient input of "somewhat structured" data is the missing link. It's a user-interface issue (NOT database screens) and a data language issue (NOT json or markdown).

"Selection" by contrast does not seem too hard. Provide an independent selection mechanism. Add this image to selection list A, that image to selection list B, those 200 images to selection list C. (That's kinda the iOS Album approach). Tag or data-augment selections A,B,C asynchronously when time allows.

By all means "AI" help is welcome - if it can be local.
