am not just trying to mark photos with tags as in tracker-tag
--add=summer /path/summer.jpg, but looking for a tag icon).

We can add the missing NAO property "nao:hasSymbol", and the range will be a nfo:FileDataObject.

Flickr/PicasaWeb, and otherwise interact with their photos such Web
services should I rely on data fetched by the Flickr and/or PicasaWeb
miners? Where can I read a bit more in what miners are supposed to do?

There is no documentation about miners yet. A miner is a process that takes information from somewhere, translate it into SparQL and send it to tracker. At the moment there is no "export" functionality in tracker and it is not trivial to add it, but it is in the roadmap for local content.

About images, the flickr/picassa miner download the basic information from the images, and set it in tracker. F-Spot can ask "all images" to tracker, and the answer is a collection of URIs: some local, some remote. GVFS should do the magic to handle those images.

+ Would it make sense to have a plugin that allows users to attach
tags to a file through Nautilus' pop-up menu, etc. ?

That would be great. It could be the first example of tags shared between applications.
