About Japanese Textbook LOD

Japanese Textbook Linked Open Data (LOD) is a dataset which includes bibliographic information for textbooks published up to now since the 7th curriculum guideline enforced in 1992, as well as the related information such as the subject areas, the subjects, teaching units, compiling prospectus and the curriculum guidelines.

Table of Contents

Overview

This project provides a LOD dataset for textbooks published up to now since the 7th curriculum guideline enforced in 1992, as well as the related information such as the teaching units, the compiling prospectus, the subject areas, the subjects, and the curriculum guidelines. Please note that information on the teaching units and the compiling prospectus are now available only for the textbooks used in 2020 at Elementary schools. As of January 2025, the dataset contains bibliographic information for 9,042 textbook titles and 917,643 triples as RDF data.

The dataset is based on a collection of textbooks held and organized by NIER Library of Education for several decades. These catalogs can be searched through Textbook Database at the NIER Library of Education website. ISBNs of the dataset are from Textbook Research Center Library catalogs.

The dataset on the learning units and the compiling prospectus are supported by JSPS KAKENHI Grant Number JP21HP8016. The original data on the learning units and compiling prospectus is also available at Textbook Compiling Prospectus Database at NIER.

Please refer to the following papers and documents on the details on the development and publishing the Japanese Textbook LOD.

LOD Vocaburaries / Data Model

The figures below are the overview of the model of the Japanese Textbook LOD. The base URI for the Japanese Textbook LOD is https://w3id.org/jp-textbook/, the base URI is shown as the prefix textbook:.

Data model of Textbook resources of the Japanese Textbook LOD
Data model of Textbook resources of the Japanese Textbook LOD, excerpt from "NEW CROWN ENGLISH SERIES 3"

Resources description

Textbook

URIs for the resources are represented as the following forms:
https://w3id.org/jp-textbook/type of schools/authorized year/textbook symbol/textbook number

Following the LOD principle, the dataset allows users to get useful information when accessing the URIs for textbooks. And you can get the RDF data of the turtle format when you access to the URIs followed by .ttl.

The properties for the Textbook resources are as follows:

Required
Non repeatable
Delimiter characters are "||". Two types of call numbers are used: The current one and the old one.
The current rule for call numbers
Textbook classification numbers - publisher number - authorized years + book number (Ex. K170.8||K10||2010)
The old rule for call numbers
Textbook classification numbers - publisher number + administrative number - authorized / usage year (Ex. K260.91||S12U||01/05). Textbook classification, publisher number, administrative number and book number are originally assign by Education Library. Usage year is derived from the item holdings of Ducation Library, so some of the year might be different from the original usage year. If year numbers are four digits, they are Gregorian calendar years. In the other cases, the numbers from 21 to 64 corresponds to 1964 to 1989 (Showa Era), the ones from 88 to 99 are 1988 to 1999, and the ones from 00 to 05 means 2000 to 2005.

And also, the merged subjects "Health and Physical Education" are defined, they are corresponding to the multiple subjects in the guidelines.
