After two years of promising to look at this, I finally did (mostly because I had to update several wikis to use SMW).

It requires only a very minor patch to GlobalFunctions.php to install, and I'm working on removing that barrier in the future.

See: http://www.mediawiki.org/w/index.php?title=Extension:NSFileRepo for full details and installation instructions.

==What can this extension do? ==

The NSFileRepo extension implements a way to restrict access to specified files and images to a given set of user groups using NameSpace protections. This provides a more fine grained security model and allows access restriction to users in specified groups.

==Usage==

Generically, you use the same syntax as a normal file/image reference link, adding the namespace between the file specifier ("File","Image", or "Media"), and the file name:

[[{FILE_NS}:{Namespace}:{Filename}]]

Example(Where "Project" is the protected namespace and "ProjectFile.pdf" is the file to which you wish to limit access):

[[File:Project:ProjectFile.pdf]]]

The standard for accessing files/images is generally:

[[File:Filename.txt]] [[Image:Filename.jpg]] [[Media:Filename.pdf]]

This extension allows you to protect access to files/images, by adding the namespace text identifier after the file namespace identifier, for example(Where "Project" is the protected namespace and "ProjectFile.xxx" is the file to which you wish to limit access):

[[File:Project:Filename.txt]] [[Image:Project:Filename.jpg]] [[Media:Project:Filename.pdf]]

Limitations of security are the same as for Extension Lockdown. To review these limitations, [[Extension:Lockdown#Additional_measures | please reference here]].

To use the full capabilities of this extension (e.g., specific namespace protections), you will need to install and use the namespace protections provided through [[Extension:Lockdown]].

This extension was made possible by the introduction of Repository Classes by Tim Starling - an elegant and brilliant implementation. It uses a new Local Repository class mechanism. Technical details on how this extension works can be found [[Extension:NSFileRepo/DOC | here]].

This extension has only been tested on 1.15.0, but should work on everything

= 1.13.0

I will be testing 1.13.0 and 1.14.0 within the next couple of days. As always, I appreciate any help/advice/support.

Hope this helps!
