Etiquette

I am currently running a demonstration copy of Etiquette at http://etiquette.voussoir.net where you can browse around. This is not yet permanent.

What am I looking at

Etiquette is a tag-based file organization system with a web front-end.

Documentation is still a work in progress. In general,

• You must make the etiquette package importable by placing it in one of your lib paths. I use filesystem junctions for this purpose.
• Run python etiquette_flask_launch.py [port] to launch the flask server. Port defaults to 5000 if not provided.
• Run python -i etiquette_repl.py to launch the Python interpreter with the PhotoDB pre-loaded into a variable called P. Try things like P.new_photo or P.digest_directory.

Project stability

You may notice that Etiquette doesn't have a version number anywhere. That's because I don't think it's ready for one. I am using this project to learn and practice, and breaking changes are very common.

Project Structure

• etiquette
  The core backend package.
• frontends
  Ideally the backend should be frontend-agnostic. Even though the Flask interface is my primary interest, it should not feel like it must be the only one. Therefore I place it in this folder to indicate that other frontends are possible too.
  • etiquette_flask
    This folder represents the flask server as somewhat of a black box, in the sense that you can move it around and just run the contained launch file.
    • etiquette_flask
      This is the package that contains all of the site's actual API code.
• utilities
  For other scripts that will be used with etiquette databases, but are not part of the library itself.

To do list

• Make the wording between "new", "create", "add"; and "remove", "delete" more consistent.
• User account system, permission levels, private pages.
• Improve the "tags on this page" list. Maybe add separate buttons for must/may/forbid on each.
• Some way for the database to re-identify a file that was moved / renamed (lost & found). Maybe file hash of the first few mb is good enough.
• Debate whether the UserMixin.login method should accept usernames or I should standardize the usage of IDs only internally.
• Ability to access user photos by user's ID, not just username.
• Should album size be cached on disk?
• Replace columns like area, ratio, bitrate by using expression indices or views (width * height etc).
• Add some way to support large image albums without flooding the search results. Considering a "hidden" property so that a handful of representative images can appear in the search results, and the rest can be found on the actual Album page.
• Add a Photo.merge to combine duplicate entries.
• Generate thumbnails for vector files without falling victim to bombs.
• Allow photos to have nonstandard, orderby-able properties like "release year". How?
• Make the FFmpeg path configurable. Some kind of global config? Or part of the database config file? It's not like every photodb needs a separate one.
• Improve the appearance of album page. Too many section headers and the "Create album" interface should allow giving a title immediately.
• When users have '%' or '#', etc. in their username, it is difficult to access their /user/ URL. I would prefer to fix it without simply blacklisting those characters.

To do list: User permissions

Here are some thoughts about the kinds of features that need to exist within the permission system. I don't know how I'll actually manage it just yet. Possibly a permissions table in the database with user_id | permission where permission is some reliably-formatted string.

• Preventing logged out users from viewing any page except root and /login.
• Uploading photos (can_upload)
  • File extension restrictions
• Add / remove tags from photo
  • My own photos (can_tag_own)
  • Explicit individual allow / deny (can_tag_photo:<photo_id>)
  • General allow / deny (can_tag)
• Deleting photos
  • etc
• Creating albums
  • As children of my own albums
• Add / remove photos from album, edit title / desc.
  • My own albums (can_edit_album_own)
  • Explicit (can_edit_album:<album_id>)
  • General (can_edit_album)
• Deleting albums
  • etc
• Creating tags (can_create_tag)
• Deleting tags (can_delete_tag)
  • Only those that I have created (can_delete_tag_own)
  • Any time vs. only if they are not in use (can_delete_tag_in_use)
