- An iDevice should know what resource files it needs
- But, it needs the webui.Block to tell it
- What about icons? --- does this depend on the style?
- Node should have a resources() method which asks all its iDevices what resource files they need and filters out duplicates
- Manifest should ask each Node what files to add under <resource> in the imsmanifest.xml file
- Adding an image to an iDevice - should we take a temporary copy of it, or load it into memory (much faster, more memory)
- When the package is saved we include the resoure file in the elp (zip) file
- When the package is loaded we need to unzip the elp file somewhere? or We serve the image from memory (much faster)
- Adding some other kind of resource file (e.g. PDF) Twisted won't know how to display, just show a link
- take a temporary copy
- save / load for elp (zip) file
- ScormExport? and WebsiteExport? should make sure to copy the resource files from their locations to their outputs
- Do we need a repository which images a saved in before they can be used?
- leave to a later iteration?
