Themenstrukturierte Daten: Alle Beiträge als "mainEntityOfPage" deklariert

Entwickler
1

Im strukturierten Datenmodell sollte nur ein Objekt als mainEntity / mainEntityOfPage deklariert werden.
Siehe “mainEntity” - Hintergrundinformationen - Datenmodell - schema.org

Derzeit wird jeder einzelne Beitrag als mainEntityOfPage deklariert.

Google betrachtet jede Seite (= URL) als ihren eigenen Kontext. Daher ist es möglich, einen Beitrag pro URL als mainEntity zu deklarieren – z. B.

  • https://DOMAIN/t/SLUG/43: Hauptentität ist #post_1
  • https://DOMAIN/t/SLUG/43?page=2: Hauptentität ist einer von #post_10 bis #post_19
  • https://DOMAIN/t/SLUG/43?page=3: Hauptentität ist einer von #post_20 bis #post_29
  • […]

Siehe auch Diskussion zu schema.org über “Pagination von ItemLists” und Google: pagination for ItemList · Issue #1714 · schemaorg/schemaorg · GitHub

  • pagination for ItemList · Issue #1714 · schemaorg/schemaorg · GitHub
  • pagination for ItemList · Issue #1714 · schemaorg/schemaorg · GitHub

Der obige Auszug aus der Entwicklerdokumentation von Google ist möglicherweise veraltet, da er derzeit fehlt: General Structured Data Guidelines | Google Search Central  |  Documentation  |  Google for Developers

Hat dies keinen Bezug zur Verwendung von: DiscussionForumPosting - Schema.org Type

Wir verwenden dies für jeden einzelnen Beitrag. Es sieht so aus, als ob wir es nur für den ersten Beitrag verwenden und dann Comment - Schema.org Type für den Rest verwenden sollten.

Auf diese Weise werden all die wiederholten Titel, Paginierungs-Sachen und der Rest der Dinge, die nicht gut passen, beseitigt.

Google kümmert sich möglicherweise nicht wirklich um Untertypen wie DiscussionForumPosting und ordnet diese stattdessen dem übergeordneten Typ Article zu.
Dadurch könnte Discourse aus Googles Sicht eher wie ein Blog mit Articles plus Comments aussehen.

Vielleicht gibt es eine andere Möglichkeit, die Beziehungen zwischen DiscussionForumPostings klarer zu gestalten:
z. B. durch die Verwendung von about - Schema.org Property, um den übergeordneten Beitrag innerhalb jeder Antwort zu deklarieren.

post_1 (mainEntityOfPage)
|
+-- post_2 (about post_1)
|
+-- post_3 (about post_1)
|   |
|   + post_4 (about post_3)
|   + post_6 (about post_3)
|
+ post_5 (about post_1)

Es gibt eine Diskussion darüber, wie DiscussionForumPosting verwendet werden soll:

Eine Meinung – siehe: We have DiscussionForumPosting but no DiscussionForum... · Issue #125 · schemaorg/suggestions-questions-brainstorming · GitHub

Die Beschreibung von DisccussionForumPosting lautet „A posting to a discussion forum.“ (Ein Beitrag in einem Diskussionsforum).

Ein typisches Forum besteht aus Kategorien. Kategorien enthalten Foren, und ein Forum enthält Themen. Ein Thema enthält 1 oder mehr Forenbeiträge.

Die Beschreibung scheint darauf hinzudeuten, dass dieses Schema für einen einzelnen Forenbeitrag gilt, aber das Beispiel scheint zu zeigen, dass es sich um ein Thema handelt, das mehrere Forenbeiträge von mehreren Autoren enthalten kann.
