I am not sure what the policy is for components with such strong restrictions. So I guess this is a question back to the group: What are requirements for components within Django with regard to system architecture? Are components required to work on distributed systems? If there is no general ans

Your analysis is spot on, PostGIS references the path to off-db rasters using an absolute path, which needs to be resolved on the PostGIS server. I guess a developer could map a folder (via samba for example) on the PostGIS server to match that of the Django server so that both servers share th

This is an interesting idea and approach, thanks Piero for the suggestion and the proposed solution. I agree with Piero and Adam, it would be a great addition to the raster field. Especially for large volumes of data (not only for individual large files, but also for many small files). Raste
