Responsibilities
The Multimedia team is responsible for features that provide a richer experience and support more media contributions on Wikipedia, Commons, and MediaWiki sites.

We develop features to:
 * improve the viewing experience for our readers
 * develop feedback and curation tools

We are also upgrading our current infrastructure to:
 * improve the upload pipeline
 * implement structured data
 * better integrate multimedia across all our sites.

Overview

 * Multimedia

Main projects
At this time, our two main projects are:
 * Media Viewer, an immersive multimedia browser; and
 * UploadWizard, an incremental upgrade and code refactoring of our contribution pipeline.

Next projects
Here is our Multimedia Vision for 2016, to give you a sense of what we are working on this year. In coming months, we will be working on a variety of projects to help our users view, contribute, curate and use images, sound and video files. We believe that audio-visual media offer a unique opportunity to engage a wide range of users to participate productively in our collective work.


 * UploadWizard

Responsibilities

 * Attract and support volunteer technologists so that they can become an even more powerful force in driving improvement on the website
