A subject in this dataset is corresponding to an item where textbook creators apply for the authorization of the textbook. This means that most of the subjects are equivalent with subjects in the curriculum guidelines, but some of them are different ones. For instance, some subjects such as Maps and Penmanship are defined as a subject while they do not exist in the guidelines. And also, the merged subjects "Health and Physical Education" are defined, they are corresponding to the multiple subjects in the guidelines. Note that a subject resources are linked from a subject area with a <code>textbook:hasSubject</code> property. URIs for the subject resources are represented as follows:<br><code>https://w3id.org/jp-textbook/curriculum/<var>type of schools</var>/<var>year of enforcement</var>/<var>subject area name</var>/<var>subject name</var></code>
Link to the blank node resource(s), which consist of properties <code>textbook:CPtype</code>, <code>schema:name</code>, and <code>schema:pagination</code>. This property values are repeated.

Link to the blank node resource(s), which consist of properties <code>rdf:value</code> and <code>schema:note</code>. If there are multiple resources, this property values are repeated.
Link to the blank node resource(s), which consist of properties <code>schema:isPartOf</code> and <code>schema:pagination</code>. If there are multiple textbooks, this property values are repeated according to the number of textbooks times.
Link to the expand course of study item, represented as <code>cs:<var>course of study code</var></code>. The "Transcribed Course Of Study Item(Code)" are expanded to include both roots and leaves.
It represents the details of the Courses of Study Items corresponding to the unit. It is associated with the Courses of Study resources shown as cs:Course guidelines code. It is expanded from the "Course of Study Item from Compiling Prospectus" to include higher- and lower-level items in the hierarchy.
This property refers to the section numbers of the corresponding courses of study items described in the compiling prospectus. This is a transcription of the information written in the compiling prospectus.

Link to the catalogue resources, represented as <code>textbook:catalogue/<var>type of school</var>/<var>first published year</var></code>. Since version 11.0, this property has changed to link to all the related catalogues.

Link to the blank node resource(s), which consist of either of properties 1) <code>nier:recordID</code> and <code>nier:callNumber</code>, or 2) <code>textbook-rc:recordID</code> and <code>textbook-rc:callNumber</code>. If there are multiple holdings in a library, this property values are repeated according to the number of holdings times.
Link to the subject resource, represented as <code>textbook:curriculum/<var>type of school</var>/<var>year of curriculum guideline</var>/<var>subject area</var>/<var>subject</var></code>. Note that if the type of the subject is Special (<code>textbook:subjectType</code>), the subject is deternmined automatically by the longest match of the Subject name from the title of the textbook, and it does not added by the Library of Education. Some exceptional data is resolved by Drs. Egusa and Takaku.

Using language tags, Japanese name, transcription of the name, and English name are shown. The meanings of language tags are as follows: <dl><dt>@ja</dt><dd>Japanese name (Kanji)</dd><dt>@ja-Hira</dt><dd>Japanese name (Hiragana). The name of the subject area is transcribed in Hiragana.</dd><dt>@en</dt><dd>English name of the subject area</dd></dl>Note that English names are unfficial one. Translation is done by the maintainers of this dataset. While we could not find the official English translations for the subject area, we refer to the tentative translations in the curriculum guidelines, and the English guide entitled "Education in Japan" published by the MEXT.
