Simply add a category to an Object

Matthew Barben

Hi There, 

I am just wondering if it is possible to simply add a new category object without blanking the previous one. 

example - Business Workspace has X Category applied - i want to add another category Y

Currenty I can add category Y by

1. Creating metadata object
2. Creating an attribute group - and populating that with StringValue
3. Apply the Attribute Group to the Metadata object
4. I then get the node (called existing node)
5. Then the only option (as I can see it) is to set the Metadata on the node (e.g.g existingNode.Metadata = metadata) and run an update (e.g. docment.UpdateNode(ref otauth, exstingNode)

This then removed Category X and only applies Y. Is the only way to extract the category information for each node I wish to process, populate that information into a new attribute group object and apply X and Y back to the object (just seems a little overkill, that is all). 

Regards,

No worries, I found the right hammer (sample code below):

int categoryY = 162669; // ID of Cat I want to update

 

//create docMan client

DocumentManagementClient docman = new  DocumentManagementClient();

OTAuthentication otAuth = new OTAuthentication();

otAuth.AuthenticationToken = authToken;

 

// Setup Attribute Group for Category Y

AttributeGroup yAttGroup = new AttributeGroup();

yAttGroup = docman.GetCategoryTemplate(ref otAuth, VIPcategoryID);

 

// Sets Value for Y attribute

StringValue Y = new StringValue();

Y.Values = new string[1];

Y.Values[0] = "Y";

Y.Key = "162669.1.2";

Y.Description = "VIP Flag";

yAttGroup.Values[0] = Y;

 

int dataID = 12345; // Node ID that want to update

 

Node existingNode = docman.GetNode(ref otAuth, dataID); // Set Node

Metadata metadata = new Metadata(); //Create Metadata object

metadata = existingNode.Metadata; //Populate Metadata Object with Existing Node values

AttributeGroup vendorCat = new AttributeGroup(); // Create Attribute Group for vendor Information

vendorCat = metadata.AttributeGroups[0];// Populate attribute group

metadata.AttributeGroups = new AttributeGroup[2];//create attributes groups for metadata object

//populate the Attribute Groups object with Attribute Group objects

metadata.AttributeGroups[0] = vendorCat;

metadata.AttributeGroups[1] = vipAttGroup;

existingNode.Metadata = metadata; // Set the Metadata objects back onto the node

docman.UpdateNode(ref otAuth, existingNode);//Update Node
