In my work we produce a large number of architecture reports usually between 20 and 100 pages every year. They must be high quality and are currently being produced in Indesign. However this creates an important barrier, because not all collaborators know how to use InDesign or have it installed on their machine. Also the reports are meant for publication in three different formats: 1. a classical booklet (A4) format, 2. as a nice PDF optimized for the web, and 3. as a presentation-friendly version.
Now I was wondering if there wasn't a better way to do that. Personally I often use LaTeX or markdown (with pandoc) to create PDFs. Using that would allow me to simply switch between different layouts and I would always receive a professional result. However, such a solution would be too much of a technical barrier as most (100+) collaborators are architects and will not be interested in learning LaTeX.
So, can you think of a professional software solution / tool chain that could fulfill our requirements (separation of content and layout, collaborative, low technical barrier)?
