I would like to see this as well. It is a must for an image organizer.

I would like to know what progress of resolving this issue is.
I am adding similar functionality for my own purposes.
My idea is to add SQLite database which will hold additional attributes.
What I have made is image table (filename, label, description, tags, date, md5sum, width, height, rating) which for test purposes is populated after clicking on thumbnails. Next I have created option_group table for groups of options like persons, places etc. and option table with options like John Doe, London etc. Finally image_option table keeps references of options assigned to images.
For now I have:

• populating database with images (after clicking on thumbnail),
• editing user fileds eg. label, description, tags, rating (it will need widget with stars or something),
• displaying groups of options and options in tab (File system goes to one tab, Database goes to another),

What I want to add:

• browse images in db and filter them by options, year, month etc.,
• search images db,
• edit group of options and options,
• set paths for indexing and add auto-reindexing,
• allow converting db to relative paths (ralative to db path) for use on DVD or USB stick and easy access from Linux and Windows,
• automatically reindex moved photos by md5 sum,
• caluclate new md5 sum for modified photos.

Hey krzyc!

Regarding progress of image tags, I am about to start experimenting and writing the code according to the design, I estimate this to be ready in about 4 weeks (working only on weekends...)

The image tags feature design in Phototonic is simple, and does not require using additional libs. It is purely based on Exif, or rather IPTC Keywords tag (I always hated software that wants to "manage" your media in its own DB separated from the file system, most notable are music players).
The only data that Phototonic will save in its configuration is the "Known tags" list.

The work flow will consist of a new Tags dock that enables the user to perform various tags operations.
The dock will contain a list with entries, it should be possible to have 3 states per entry (I have not yet decided which control to use exactly).
This dock by default will be populated with the "Known tags" list.

When thumbnails are loaded for a directory, Phototonic will read the keywords for the images being loaded, and change the state of an entry for each unique tag it sees, for example: if the "Amsterdam" tag is encountered in images contained in this directory, the "Amsterdam" tag in the list should be in a state indicating that it is available in the directory.
If a tag is encountered that is not in the "Known tags" list, it will be added to it.
Eventually, when all thumbnails have been loaded, the dock should display all of the known tags, while the tags available in the directory are marked.

When a user selects a thumbnail or multiple thumbnails, the tags dock should change to reflect what are the tags associated with the selected images, also enabling to add / remove tags for the selected items, creating new tags and deleting tags.

In addition, the user can choose to display only images associated with specific tags (the 3rd state).
The dock should have a general appearance such as the following example:

Done.

How do I add new tags to an image? Cannot find such a fuction.

Hey fguzm!
When you select an image or multiple images, you can create a new tag and assign it to them using the new tags dock, like in this screenshot for example:

just curious why you chose IPTC instead of XMP tags? Any chance on an option to write to either? Also is there a way to edit other IPTC fields or only "keywords"?

[oferkv]

Hey.
I think I was inspired by how gThumb's implementation.
But does it matter what keywords are used?
Editing image metadata would be a nice feature...

[howudodat]

I have found that it doesn't matter too much whether to use IPTC or XMP, unless one is a Photoshop fanatic :). It would be nice however to edit other IPTC metadata (title, caption, etc)

Opened issue for this: Allow editing metadata (Exif fields...). #207
