At the end of each haiku, <unique number> (in Kanji format) is displayed with a link to RDF information.
Haiku RDF is modeled with a Work and Expression(s), where the latter represent variations created in a elaborating process
A work has an rdfs:label which is selected among variations based on some critical commentaries, while each expression is also represented with an rdfs:label in its entity. A work and its expression(s) are related with schema:workExample. Also, if a variant expression exists, a work has corresponding schema:alternateName.
If different notation(s) (Kanji and Kana usage) present, they are treated as the same Expression as long as basic form are the same, and they are described with schema:name respectively.
While prefaces and signatures may vary in different original texts, only representative ones are described in a Work entity.
Original texts, critical commentaries and English translations
Original texts of each expression are described with dct:source, although some minor ones might be omitted.
Each critical commentary mentioning a work/expression is described with schema:subjectOf in the expression.
Open license translations, e.g. Matsuo Bashō - Two Hundred Selected Haiku, are related with schema:workTranslation from a work. At this moment, 329 translations for 287 works are included.
