最終更新: 2026-09-29

Demandとは?

Demand は、schema.org で決められている型のひとつです。Intangible の一種として定義されています。形のないもの(価格・評価・数量・サービスなど)を表すとき に使います。

schema.org の定義(原文)

A demand entity represents the public, not necessarily binding, not necessarily exclusive, announcement by an organization or person to seek a certain type of goods or services. For describing demand using this type, the very same properties used for Offer apply.

どこに位置する型か

Thing → Intangible → Demand

上にある型ほど広い意味です。書くときは、そのページに一番近い(下にある)型を選びます。

Googleのリッチリザルトに対応していますか?

公式ギャラリーには載っていません。ただし、載っていない型を書いてはいけないという意味ではありません。schema.org の語彙は、検索結果の見た目を変えるためだけのものではなく、ページが何について書かれているかを機械に伝えるためのものです。リッチリザルトが出るかどうかと、書いてよいかどうかは別の話です。

gtinText、URLA Global Trade Item Number (GTIN). GTINs identify trade items, including products and services, using numeric identification codes. A correct gtin value should be a valid GTIN, which means that it should be an all-numeric string of either 8, 12, 13 or 14 digits, or a "GS1 Digital Link" URL based on such a string. The numeric component should also have a valid GS1 check digit and meet the other rules for valid GTINs. See also GS1's GTIN Summary and Wikipedia for more details. Left-padding of the gtin values is not required or encouraged. The gtin property generalizes the earlier gtin8, gtin12, gtin13, and gtin14 properties. The GS1 digital link specifications expresses GTINs as URLs (URIs, IRIs, etc.). Digital Links should be populated into the hasGS1DigitalLink attribute. Note also that this is a definition for how to include GTINs in Schema.org data, and not a definition of GTINs in general - see the GS1 documentation for authoritative details.
gtin12TextThe GTIN-12 code of the product, or the product to which the offer refers. The GTIN-12 is the 12-digit GS1 Identification Key composed of a U.P.C. Company Prefix, Item Reference, and Check Digit used to identify trade items. See GS1 GTIN Summary for more details.
gtin13TextThe GTIN-13 code of the product, or the product to which the offer refers. This is equivalent to 13-digit ISBN codes and EAN UCC-13. Former 12-digit UPC codes can be converted into a GTIN-13 code by simply adding a preceding zero. See GS1 GTIN Summary for more details.
gtin14TextThe GTIN-14 code of the product, or the product to which the offer refers. See GS1 GTIN Summary for more details.
gtin8TextThe GTIN-8 code of the product, or the product to which the offer refers. This code is also known as EAN/UCC-8 or 8-digit EAN. See GS1 GTIN Summary for more details.

プロパティ入る値の型schema.org の説明(原文)どの型から
additionalTypeText、URLAn additional type for the item, typically used for adding more specific types from external vocabularies in microdata syntax. This is a relationship between something and a class that the thing is in. Typically the value is a URI-identified RDF class, and in this case corresponds to the use of rdf:type in RDF. Text values can be used sparingly, for cases where useful information can be added without their being an appropriate schema to reference. In the case of text values, the class label should follow the schema.org style guide.Thing
alternateNameTextAn alias for the item.Thing
descriptionText、TextObjectA description of the item.Thing
disambiguatingDescriptionTextA sub property of description. A short description of the item used to disambiguate from other, similar items. Information from other properties (in particular, name) may be necessary for the description to be useful for disambiguation.Thing
