2.3.3.2.2 Document Summary Information Property Set

  • Article

This section defines a simple OLE property set as specified in [MS-OLEPS] containing application-defined properties. This property set conforms to [MS-OLEPS] section 2.21 and [MS-OLEPS] section 2.23 with regards to the stream name requirements and format identifier GUID for the FMTID_DocSummaryInformation property set. The Document Summary Information property set is contained in the document stream named "\005DocumentSummaryInformation" and contains a fixed set of recognized properties, which are specified in the following section. In addition, this property set MUST have the following:

  • This property set MUST have its PropertySetStream structure Version field set to 0x00000000.

  • This property set MUST have its PropertySetStream structure CLSID field set to GUID_NULL.

  • This property set MUST have a PropertySetSystemIdentifier structure (section 2.3.3.1.1) for its PropertySetStream structure SystemIdentifier field.

The total size of this property set’s PropertySet structure ([MS-OLEPS] section 2.20) MUST be padded to a multiple of 4 bytes. The padding, if needed, MUST be located after the final property value of the property set and MUST be the minimum size required to produce a PropertySet structure with a size that is a multiple of 4 bytes. The contents of the padding are undefined and MUST be ignored. The PropertySet structure’s Size field MUST include the count of padding bytes in its calculation.
