SPWeb.ParserEnabled property

Gets or sets a value that specifies whether parsing is enabled for document libraries of the website.

Namespace:  Microsoft.SharePoint
Assembly:  Microsoft.SharePoint (in Microsoft.SharePoint.dll)

public bool ParserEnabled { get; set; }

Property value

Type: System.Boolean
true if parsing is enabled; otherwise, false. The default is true.

As a practical matter what it means for this property to be true is that when a document is added to a document library, the values of the fields in the list item for the document are added to the metadata properties of the document file. For example, if you upload a Word document and then download it again, you can see the field values in the advanced properties dialog of the Word file.
