Skill Project-PLATEAU/skills/skills/plateau-api

PLATEAU 配信サービス(api.plateauview.mlit.go.jp)の REST / GraphQL API を使って、PLATEAU の 3D 都市モデル(3D Tiles, MVT, CityGML)データの配信 URL・データカタログ・属性情報を取得するときに使う。「PLATEAU の建築物データを取得したい」「3D Tiles の URL がほしい」「CityGML を絞り込んで取りたい」「データカタログ API」「複合 tileset.json」「PLATEAU GraphQL」などの場面で起動。From its SKILL.md

2 things to look at

  • no licenseNo license file was found in the repository. Code published without one is not open source by default, so using it at work is a question for whoever answers licensing questions where you are.
  • 1 stars1 stars. Stars are a popularity signal and not a quality one, but at this level it is likely that nobody has read this closely except its author, and you would be relying on your own review.

What its file declares

Copied from the file, not written here

The file declares its own license as MIT. That is the author’s claim about this one file, and it is not the same thing as the license GitHub reports for the repository, which is listed with the other numbers below.

スキーマを取得する

REST(OpenAPI 3.0 JSON):

curl -fsSL https://api.plateauview.mlit.go.jp/openapi.json

GraphQL(introspection):

curl -fsSL -X POST https://api.plateauview.mlit.go.jp/datacatalog/graphql \
  -H 'Content-Type: application/json' \
  -d '{"query":"query IntrospectionQuery { __schema { queryType { name } mutationType { name } subscriptionType { name } types { ...FullType } directives { name description locations args { ...InputValue } } } } fragment FullType on __Type { kind name description fields(includeDeprecated: true) { name description args { ...InputValue } type { ...TypeRef } isDeprecated deprecationReason } inputFields { ...InputValue } interfaces { ...TypeRef } enumValues(includeDeprecated: true) { name description isDeprecated deprecationReason } possibleTypes { ...TypeRef } } fragment InputValue on __InputValue { name description type { ...TypeRef } defaultValue } fragment TypeRef on __Type { kind name ofType { kind name ofType { kind name ofType { kind name ofType { kind name ofType { kind name ofType { kind name ofType { kind name } } } } } } } }"}'

HTTP キャッシュ

複合 tileset.json / MVT tilejson.json / CityGML リダイレクトの各エンドポイントは弱 ETag (W/"...") と Cache-Control: no-cache, must-revalidate を返す。If-None-Match を送れば 304 Not Modified で短絡する。-latest URL でも内容が変わらなければ 304、差し替わると ETag が更新されて新しいデータに追従する。

注意

  • API は試験運用中。スキーマ・URL・レスポンスは予告なく変更され得る。SLA なし。
  • /datacatalog/plateau-datasets のレスポンスは 2MB 以上。gzip 対応。
  • GraphQL は複雑すぎるクエリに制限あり。
  • CityGML Pack API に投入できる URL は PLATEAU CMS(assets.cms.plateau.reearth.io)のファイルのみ。生成 zip は一定時間後に削除される。
