Flat glass roof with retractable panels

[charlottesave]

I'm trying to create a flat glass roof with retractable 'skylight' panels set in steel beams.  I've created a flat angled roof out of a solid which achieves the desired shape.  I'm just stuck a little on how I think take this further to create the glass roof effect and the panels.  D5 Rooftop Bar .pdfD5 Rooftop Bar .pdf

Not clear what/how should retract. A 3d flyover could help understand. Or add an image of existing similar product. or post your file. Is your pdf drawing a top view of a sloping roof, eg the center rectangle represents a ridge or valley?

 

Are these intended to slide left to right into a stack, each panel independent and on its own track? (Weather tight could be an interesting problem) 
 

or do these independently slide up/down (paper direction) toward that ridge/valley?

 

forum wants to help, but needs some detail.
