This page is dedicated to the design and discussion of the different item types types (Item Revision Types really) within the new Moin Storage Engine.
ItemRevision (Abstract Base Class)
- Attachment
- Image
- Sound
... (maybe this should be subclassed as "inline" and "opaque", for, e.g. types that can (image/jpeg) or cannot (application/msword) be displayed in a browser instead of trying to subclass for every possible filetype... -- TheAnarcat 2006-08-10 08:54:17 )

UnderlayRevision: Should this be a subclass of Page or its own? Since we're using a Rubik we can easily have Page's decendants underneath a seperate UnderlayRevision too.
Each attachment or may be a page too will need some additional informations, e.g. alt text. I don't know currently how we could add this infos to the items. I like to collect here what is wanted for attachments. For current code one idea is to add for each attachment file a file with this info and actions have to try if it exists and then to do the same with it as with the attachment itselfs. The additional files are hidden for the attachlist if they start with a dot. They should be easily used to render its content for an attachment info action. -- ReimarBauer 2007-04-07 08:51:28
