Data entities that are independently stored

Package Specification

ShortFloats: BudgetValue (priority/durability/quality) and TruthValue (frequency/confidence)
Stamp: serial numbers and creation time associated to a TruthValue
Sentence: a Term, a TruthValue, and a Stamp. A Sentence can be a Judgment, a Goal, or a Question.
Task: a Sentence to be processed.
TermLink: built in pair between a compound term and a component term.
TaskLink: special TermLink refering to a Task, whose Term equals or contains the current Term.
Concept: labeled by a Term, contains a TaskLink bag and a TermLink bag for indirect tasks/beliefs, as well as beliefs/questions/goals directly on the Term.
Item: Concept, Task, or TermLink

in NARS, each task is processed in two stages:

Direct processing by matching, in the concept corresponding to the content, in one step. It happens when the task is inserted into memory.
Indirect processing by reasoning, in related concepts and unlimited steps. It happens in each inference cycle.
