Workflow and interface redesign

  • most likely cases (own work,
  • simple, not too verbose
  • but we need to educate them a little => quick tutorial for first-time users

Related bugs:

Staging area

aka holding area, incomplete uploads, quarantine section, etc.

Related bugs:

  • bugzilla:4995: Ability to block users from uploading files only
    Listing this bug only as a reminder. This is probably not the way we want to handle this kind of users.
  • bugzilla:2537: Ability to preview summary in "Upload file" page.
    Will probably be INVALID after the redesign of the upload process, since we don't want any (wiki)text on the upload page itself. Preview will be included in the next step of the upload where the user provides pieces of information about their file.
  • bugzilla:16437: Ability to preview vector/re-rendered images in Special:Upload "warning" interstitial.
  • bugzilla:20326: Option to strip some metadata on upload (GPS/geolocation privacy)

Multiple Upload

Allow several files to be uploaded at the same time (5 to 10)

  • possibility to add the same description(s), license(s), category(ies), geocode to all the pictures
  • but also to specify custom data for each

Related bugs:

  • bugzilla:488: Upload more than one file at a time
  • bugzilla:16751: Support multiple file uploads via Special:Upload (backend/infrastructure)
  • bugzilla:16752: Support HTML 5 multiple upload control

Smart upload

Metadata extraction

Extract relevant metadata from files on upload

  • Priority: EXIF
  • IPTC and XMP would be nice too, especially since XMP can host multilingual descriptions
  • where we store these metadata (existing templates, structured data) will be determined later.

See Multimedia:Metadata#Metadata extraction

Upload by URL

from 3rd-party websites (flickr, Internet Archive, etc.)

  • Check if the source or the file provides useful metadata
  • Check if the source or the file provides copyright information

Edit location

Widget allowing to add/modify/remove geographical information using OpenStreetMap

Annotations tool

Tool to annotate pictures

  • review the existing annotation tool, see if it's scalable, it import/export is possible/easy, if it can be improved, etc.
  • integrate a way to tag people? places? things?
  • make it work with other view sizes

Image editing tools

Basic image editing tools:

  • lossless crop
  • lossless rotate
  • preserve metadata
  • add possibility to save the resulting image with another name (not really necessary for rotate, but probably needed for crops)

  • bugzilla:20712: Anchor tag surrounding a thumbnail's img tag no longer has a title attribute.
  • bugzilla:21981: Auto file name/label feature for <gallery>
  • Sometimes the caption is much more detailed than the description on the file description page (example: Fault-tolerant system). Yet when the user clicks the file to see a larger size, they see the file description page's text, and not the caption with the context of the article. We have to find a better way to handle this (also related: caption / description / alt text).

Crosswiki integration

Unified watchlist

A way to integrate the watchlist on Commons to a watchlist on another wiki. Or a list of any watchlists.

  • Via RSS feeds entered manually by the user
  • Via special page with checkboxes (include a select/unselect all).
  • Reasons: A fair amount of Wikimedia users don't want to upload files to Commons because it requires them to have a separate watchlist. Another fair amount of users complain that they aren't properly notified when they get messages about their files on their talk page on Commons.

Special page for global settings

Could be used for global preferences in the end, but would first be used for global watchlist. Allow some sort of sorting with JS magic; possible keys:

  • number of edits on the wiki
  • project (all wikipedias together, then sorted alphabetically by language)
  • language (same)

Cross-wiki file move & copy

Facilitate one-click file moves from any Wikimedia wiki

  • and one-click file move from Commons to any Wikimedia wiki (e.g. for unfree content that was uploaded to Commons but has to be moved to a local wiki with the relevant EDP)
  • and one-click file copy from any Wikimedia wiki to any Wikimedia wiki (e.g. for unfree content available on a wiki with the appropriate EDP, and that has to be copied to another wiki with a similarly appropriate EDP).
  • later: add move from any MediaWiki website / CMS to Commons
  • to keep in mind: watchlist

Multilingual support

User-friendly language setting

Possible solutions:

  • easy: use lang of the SUL'd user's home wiki as default language in preferences
  • harder: global language setting (overridden by local specific settings)
  • and in any case, add the language selector to the sign up page on multilingual wikis like Commons, so that users don't need to go in their preferences and change the language as soon as they register.
  • Make the info public? in order to make it easier for other people to communicate with the user

  • bugzilla:6466: Enable login language selection links on Commons, Meta, MediaWiki, and
    See also rev:14901 (language selector bar)

Multilingual communication

Communication between users is difficult on multilingual sites like Commons; people have to communicate using auto-translated templates.

Multilingual search

Multilingual categories

Allow translations of categories

  • see if this can be done as a larger overhaul of the interwiki system (bugzilla:11423)
  • talk with Duesentrieb, Siebrand and perhaps interwiki bot owners
  • see also Multilingual MediaWiki

Better language picker

Unlike just about every website on the planet, we have a need to allow quick switching between over 356 languages or dialects, sometimes on the same page.

Wikimedia's current solution is to present a menu of 356 choices to scroll through, using the name of the language in the language, ordered by ISO code.

The problem cannot be solved by any ordering, as that will always have languages that are harder to find. It is also sub-optimal to mix code pages, listing devanagari alongside roman letters, since there is no obvious order.

So we want to do away with a scrolling menu altogether. We want to use a text input that auto-completes with suggestions, much like the search box today. However, this auto-completion also knows about all the translations we have for all language names as well as their ISO codes. So to get to German, you could type de for its ISO code or Deutsch. You could also type ge which would give you "de - Deutsch (German)" among its choices, or even the Chinese name for German. We avoid the N**2 problem since if we do not have a translation for a particular language name in a particular language, that simply doesn't become part of the choices offered.

    Probably not the best way to handle this
