RFC: Decide scope of project

[osdiab]

Active list of things that I think would be interesting, not necessarily a list of things that need to be built in:

Spaced repetition scheduling algorithm

• basic implementations of classic supermemo algos (either as standalone products or as some configurations of a more general spaced repetition algorithm)
• ability to forecast/limit total amount of time/content learned/reviewed for a given period, especially after missing days/weeks/months
  • by items? or by forecasted time?
  • if forecasted time, will require some ability to ingest amount of time spent
• ability to segment groups of content, prioritize as relevant to one's life (for example, in a course you might do a chapter-by-chapter treatment of topics, stuff for the current chapter may take priority over past topics)
• flexibility for managing the types of cards and how they're presented.
  • example: in Japanese study, a simple "front" and "back" is not particularly efficient, since a word has chinese/japanese readings, translation, writing is totally different skillset, usage is too, and words can be related with one another in ways that can strengthen understanding of entire groups of vocabulary/grammar - doing cards for every permutation of these is suboptimal since lots of overlap

Technical

• ability to use this in a JS context for the web, preferably with good typings for TypeScript
• ability to use this as compiled binaries so that it can be used in native apps without needing a JS runtime
  • (combination of those two things points to something that can compile to either binary or transpile to JS attractive, like ReasonML. RFC: Decide language to write in #3 )
• Support for extending the algorithm on its own with plugins - maybe the functionality above can all just be plugins on a generic base

Documentation & usability

• some way to encourage configuration that works well for most use cases
• comparison of existing algorithms/libs and the approach taken here (RFC: Research existing spaced repetition libraries #2)
