base content type

基本解釋

The base type roles are all abstract and should not be used in content.
基本類型角色都是抽象的，并且不應(yīng)在內(nèi)容中使用。
If you need to allow more content structures than the base types allow, you can specialize directly from topic, or form your own base type.
如果您需要比基本類型允許還要多的內(nèi)容結(jié)構(gòu)，可以直接從 topic 專門化或形成您自己的基類型。
Metadata types are those that specific content types aggregate with the base types to provide specific, well-known properties that are specific to a type of content.
元數(shù)據(jù)類型是特定內(nèi)容類型與基礎(chǔ)類型聚合的類型，提供特定于某類內(nèi)容的特定屬性。
