Draft: Modeling XBlock Field Data on Components

[ormsbee]

Just jotting this down quickly for now, to expand on later (because I've had this open in a window for a week now and not hit the submit button):

Learning Core

• RawContent + TextContent for the OLX
• RawContent + TextContent for any supplementary filesystem data needed by the server for unit rendering, e.g. the HTML file that accompanies HTMLBlock.

External

• Multiple models for different aspects of XBlocks (e.g. scoring)–more granular separation than just settings vs. content.
• All unrecognized fields can go into a model with a JSONField–this is the generic XBlock field store. Though individual XBlocks can add their own custom tables later.
• Like progressive enhancement on data models.
