Overview

The Course of Study LOD is described as follows.

The Course of Study LOD publishes the content, codes, and related information of the Course of Study and Education Guidelines published by the Ministry of Education, Culture, Sports, Science and Technology as Linked Open Data (LOD). The target for LOD conversion is the latest version of the code tables for all school types of current and former Courses of Study and Education Guidelines (including partial revisions) that are currently published.

I had the opportunity to use this dataset, so this is a note on how to use it.

Building a SPARQL Endpoint

This time, we use DYDRA.

Below is the result of registration.

Creating Snorql

To make the SPARQL endpoint easier to use, I prepared Snorql.

Search Example

The following query allows you to understand the number of “Items (jp-cos:Item)” per “Course of Study (jp-cos:CourseOfStudy).”

https://sukilam-educational-metadata.github.io/etc/jp-cos/?query=PREFIX+rdf%3A+<http%3A%2F%2Fwww.w3.org%2F1999%2F02%2F22-rdf-syntax-ns%23> PREFIX+jp-cos%3A+<https%3A%2F%2Fw3id.org%2Fjp-cos%2F> SELECT+%3FcourseOfStudy+(count(distinct+%3Fs)+as+%3Fcount)++WHERE+{ ++%3FcourseOfStudy+rdf%3Atype+<https%3A%2F%2Fw3id.org%2Fjp-cos%2FCourseOfStudy>+.+ ++%3Fs+jp-cos%3AcourseOfStudy+%3FcourseOfStudy+.+ }+ GROUP+BY+%3FcourseOfStudy ORDER+BY+desc(%3Fcount)

Visualizing with Yasgui

Below is a visualization example in Yasgui. It appears that UpperSecondary (high school, jp-cos:school/UpperSecondary) has the most items.

Summary

I am grateful to the creators of the Course of Study LOD.

I hope this is helpful for using the Course of Study LOD.
