I'm currently upgrading my own handful of simple modules to Xoops 2.5.10. Some are pretty old, and I would like to have a consistent admin side as well as position them to move forward easily in future.

Can someone point me to an existing module that takes full advantage of Xmf that I can use as an example? It can even be something working with the upcoming new Xoops version. I just want to see a complete basic implementation.

Thanks,
Sherry

You might want to look at WgGallery (https://github.com/ggoffy/wggallery) - it uses some of the XMF features, PHP namespaces, uses the "common" admin GUI, etc.

It would be a good starting point to help you understand how to implement some of the newer XOOPS 2.5.x features. After that you can browse some of the recently edited modules in the GitHub modules repositories to see other examples.
