Manual:Content table/ja

content テーブルはコンテンツ オブジェクトを表現します. Its primary purpose is to provide the necessary meta-data for loading and interpreting a serialized data blob to create a content object.

content_id
ID of the content object

content_size
Nominal size of the content object (not necessarily of the serialized blob)

content_sha1
Nominal hash of the content object (not necessarily of the serialized blob)

content_model
への参照. Note the serialization format isn't specified; it should be assumed to be in the default format for the model unless auto-detected otherwise.

content_address
URL-like address of the content blob
