MediaUploader is a flexible file upload tool forked from UploadWizard.

Installation

Updating from UploadWizard
TBD

Development status
We are currently identifying and resolving issues that should be fixed before the initial release. Until then, the extension may change a lot and break compatibility, so using it is not recommended for now. See this Phabricator task for more details.

Origin and design
The idea of MediaUploader stemmed from the numerous issues with using UploadWizard on third-party wikis. The original tool was mostly designed for use by Wikimedia Commons, fulfilling its very specific needs (e.g. Wikibase support, specific licensing hacks, image-based tutorials). Third parties usually have a very different set of requirements that emphasize simplicity and flexibility. The two approaches are hard to reconcile in a single extension, especially given that UploadWizard must meet Commons' requirements and has no obligation to consider the needs of third parties. Thus, MediaUploader was born.

Main design goals of MediaUploader are:
 * Ease of use, at least as good as the original UploadWizard.
 * Configurability of all elements, well-described in documentation.
 * Ability to simplify certain elements of the wizard for wikis with less strict image description requirements.
 * Extensibility to allow for wiki-specific enhancements to be created locally.
 * No Wikimedia Commons-specific features.
