Hello, folks. Does the data model support extension of existing content classes? For instance, can I add metadata attributes to the image object model, and reflect those added attribute in the controller and view? Can I create new content classes, such as a composite class that aggregates a document file with any required image files, and have such objects managed physically as ZIP or TAR files? I realize this requires development, but my main question is: Does the framework's data model readily support such extensions? Thanks.

It should be possible to extend content types using the archetypes.schemaextender add-on.

Yes we're already using archetypes.schemaextender so extend away. Do be careful with the extending though - I'd recommend making new inherited Archetypes content types, and then customizing the templates to display these content types as well, instead of straight away adding fields to the original content types.

If you do it this way, then you'll hopefully be able to retain future upgrade compatibility with our updates, when we add stuff to them.
