content table

MediaWiki version:

≥ 1.31

The content table represents content objects. Its primary purpose is to provide the necessary meta-data for loading and interpreting a serialized data blob to create a content object.

Fields

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

Reference to content_models.model_id. 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. Currently the structure is: tt:<id> where <id> is a number referencing the text.old_id column.
