Rez's SharePoint Blog Spot

Overview

• A Document ID is a unique identifier for a document within a SharePoint 2010 site collection
• SharePoint 2010 now provides a static URL or permalink that opens the document associated with the ID, regardless of the location
• SharePoint 2010 includes new Site Collection scoped Feature called the Document ID Service.  To enable feature you can go to Site Settings --> Site Collection Features or you can launch the SharePoint 2010 Management Shell and run the following:
  • Enable-SPFeature -id docid -url “<site collection url>”

Document ID Capabilities:

• Upon activation of this feature, a new link appears under: Site Settings --> Site Collection Administration called Document ID Settings

• Settings allow the custom assignment of Document IDs with certain character prefixes
• Settings allow the resetting of all Document IDs within the Site Collection (via daily timer jobs)
  • Document ID enable/disable job
    • creates the Document ID column in the Document content type & Document ID list column available in every document library within site collections where the feature has been activated
  • Document ID assignment job
    • Assigns Document IDs to any existing documents within site collection.

• To force run these jobs go into Central Administration –> Monitoring –> Review job definitions –> click the two jobs for the appropriate web application
• Settings also allow user to select a scope to be able to input a specific Document ID in and have it pull up the document directly from this search scope index (i.e. a frequently updated index)

• Find by Document ID Web Part enables user to enter a Document ID, then constructs a "static URL" and looks up the item, this web part is located under (Site Actions –> Edit Page –> Insert (from Ribbon) –> Web Part –> Search Category –> Find by Document ID)

• Properties of each document within a document library now has a field called Document ID:

**Note: After activating Doc ID feature for existing documents within site collection, an action needs to be taken on document to cause the Document ID to appear (i.e. like check-in/check-out.)

• The Document ID URL now looks like this:
  • http://<sitecollectionurl>/_layouts/DocIdRedir.aspx?ID=34RZ5NUVTCP7-1-4
• This is a new SharePoint 2010 application ASPX page that sits in the layouts directory and is called DocIdRedir.aspx that takes a Document ID as query string parameter.
• This gives the ability to consistently reference documents as on document movement the document ID URL link does'n’t change or break, even if the document moves between sites!
• Developers now have the ability to create their own Document ID provider if they want to generate doc id’s in a specific way, they would derive from the:
  • Microsoft.Office.DocumentManagement.DocumentIdProvider

public class MyDocumentIdProvider : Microsoft.Office.DocumentManagement.DocumentIdProvider 

{ 

    // Generate doc id we want here

    public override string GenerateDocumentId(SPListItem listItem) 

    { 

        return MyClass.GenerateDocId(); 

    }

    // Use default search or call GetDocumentUrlsById before search

    public override bool DoCustomSearchBeforeDefaultSearch 

    { 

        get { return false; } 

    }  

    // implement logic to find documents if default search doesn't suffice

    public override string[] GetDocumentUrlsById(SPSite site, string documentId) 

    { 

        return new string[] { }; 

    }  

    // return default doc id initially displayed in doc id search web part

    public override string GetSampleDocumentIdText(SPSite site) 

    { 

        return "RezCorp-888--CUSTOMID"; 

    } 

}
