Microsoft SharePoint Server 2010 uses document library metadata to track which documents are actually converted copies of other documents. For each converted copy in a document library, SharePoint Server 2010 stores additional information in the following two fields:
The relationship between the original file and any converted copies remains only as long as both the original file and the copy are located in the same document library. It is a one-way relationship; SharePoint Server 2010 stores information on the converted copy that references the original document, but includes no references from the original document to the copy.any converted copies.
- ParentID A string that represents the name of the original file on which the converted copy is based.
- ParentVersionID An integer that represents the version number of the original file on which the converted copy is based.
These two columns enable SharePoint Server 2010 to determine which documents in a library are actually converted copies, and determine the original from which a specific converted copy was generated. For example, SharePoint Server 2010 uses this information to list the converted copies available for an original file on that document's settings page in the user interface.
Users can use this information also; for example, to create views that filter out the converted copies included in a document library.
The ParentID and ParentVersionID fields are columns that are actually included on each
document library in SharePoint Server 2010. However, the columns are hidden for document libraries in Web applications that do not have document converters enabled. |
