Hi Rubén, 

I would be able to help you use the GLAMwiki Toolset if you would like. 
https://commons.wikimedia.org/wiki/Commons:GLAMwiki_Toolset

The first thing you need is to get the user-permission for the account you will be using to do the upload. 
The instructions for setting up are here: https://commons.wikimedia.org/wiki/Commons:GLAMwiki_Toolset#Instructions

Step 1 is to create a user-account here: http://commons.wikimedia.beta.wmflabs.org/wiki/Main_Page
and ask for the user-permission on Beta: https://www.mediawiki.org/wiki/Help:Extension:GWToolset#Asking_for_user_rights
This is where you can do your testing.

We can then work on step 2 (whitelisting the GLAM's domain) and 3 (exporting their metadata in XML) but we can do that offlist ;-)

By the way - when you say 'their files are not in public domain', do you mean that the GLAMs are going to share their own copyrighted images under a free license? In which case - that's great, congratulations. However, if they're not - then you'll need to negotiate that first, before we even start with the technical side of uploading. 

Sincerely, 
-Liam / Wittylama

Peace, love & metadata

Hello everyone!

>From yesterday until January 7, 2016, Wikimedia Spain enters three
state museums, the Museum of Romanticism, the Museo del Traje (Costume
Museum) and the National Archaeological Museum, where I´ll work as
wikipedian in residence.

Besides promoting the Wikimedia projects in the three institutions, it
will be carried out various activities open to the public, like
edit-a-thons and training sessions, aimed to explain how Wikipedia
works and generate content related to the museums and their
collections: the nineteenth century in Spain, fashion, ethnography and
archeology. Another highlight will be the donation of multimedia files
(documents, pictures or recordings) under a free license to Wikimedia
Commons, in order to illustrate contents of the various Wikimedia
projects.

The Museum of Romanticism has cataloged more than 16,000 museum
pieces. It offers collections of paintings, miniatures, furniture,
decorative arts, prints, drawings and photographs collections, which
offer a broad panorama of the arts during the Romantic era in Spain.
The Costume Museum has collections dedicated to fashion, costumes and
ethnography, with a collection of over 170,000 pieces and documents;
these collections date from the Middle Ages to the contemporary
fashion of Spain. The National Archaeological Museum is, since 1867,
the leading Spanish institution in the preservation of historical
pieces. Its permanent collection includes over 15,000 items from
Prehistory, Early history, Roman Spain, Greece, Egypt and the Near
East, Middle Ages and Modern Age.

In relation to the uploading of files to Wikimedia Commons, what tool
do you recommend me to use? (their files are not in public domain).

Best,
