1. A system configured to allow storage and retrieval of handwriting input, comprising:
a processor,
a sensor configured to receive touch input; and
a non-transitory memory including instructions which, when executed by the processor, cause the processor to:
generate stroke data in response to handwriting input received via the sensor,
generate, by performing semantic analysis on the stroke data, semantic metadata including semantic data indicating semantics of the stroke data and purpose data determined based on the semantic data, wherein the purpose data indicates a use purpose of the stroke data,
store the stroke data, the semantic metadata, and a pen identification indicating an electronic pen used to generate the stroke data in association with each other, and
in response to a user prompt indicative of the pen identification, retrieve the stroke data and the semantic metadata corresponding to the pen identification.
