Is this project abandoned

[ttopholm]

Because it seems all documentation is down at sourceforge

Maybe you can answer this question, if I have a database with all my images in, how can I check without adding the image I want to find similar to.

and is it possible to add meta data to the images

[ttopholm]

Okay, found the docs. But how do you add keywords, it seems you need some kind of ids

[ricardocabral]

iskdaemon doesn't store keywords as text. It just stores numerical IDs as keywords. You'd need to store the textual representation of these keywords/tags/labels on another database.

The project is still warm, you can find some forks on GitHub.

There is mirror for the docs available at this time at http://isk-daemon.readthedocs.org/en/latest/

As Ricardo has answered, images are stored in DB by their IDs.

Keywords can be added to images and are used to narrow queries.
