Item Entity

Items are the atomic units of learning in Skritter, tracking reviews and learning. An item could be the writing for a character, or the tone of a word.

Also, they can cover more than one word or character, in the case of Chinese. If, for example, a simplified and traditional character have the same definition, a user can only have one item for that shared definition. However, there will be two separate items for the writing of each character. An item does not store the word information though; that's the job of the Vocab.

Properties

• id
  
• lang
  
• part
  
• vocabIds
  list of Vocab ids that this item 'covers' for this user.
• style
  
• timeStudied
  total time spent studying this item in seconds
• next
  timestamp of when it's due
• last
  timestamp of when it was last studied.
• interval
  number of seconds it was originally scheduled for (so not necessarily next - last, if last has been changed since)
• vocabListIds
  list of VocabList ids from which this item was added
• sectionIds
  list of VocabListSection ids from which the word was added. This list parallels vocabListIds.
• reviews
  number of times this item has been reviewed
• successes
  number of times this item was scored 2 or higher
• created
  timestamp of when this item was created
• changed
  timestamp of when this item was last altered in any way
• previousSuccess
  boolean, whether the last review had a score greater than 1
• previousInterval
  integer, the interval value prior to the last review

The Item entity is not mutable in any way, and probably never will be. Changes will be made indirectly, such as by banning a Vocab, adding from a VocabList, or reviewing the Item.
