openCMIS: Create an item object

Just like other cmis object (documents, policies) items can be filed (or) unfiled. You can create unfiled items using Session object, where as you can create filed items using Folder object.

What is filed item?

An item called filed, if it resides in one or more folders.

What is unfiled item?

An item called unfiled, if it do not reside in any folder.

How to create unfiled item?

Session interface provides below methods to create an item.

          ObjectId createItem(Map<String, ?> properties, ObjectId folderId);

          ObjectId createItem(Map<String, ?> properties, ObjectId folderId, List<Policy> policies, List<Ace> addAces,List<Ace> removeAces);

          

You should pass folderId as null to create unfiled items.

Below statements are used to create unfiled item.

                  Map<String, Object> properties = new HashMap<String, Object>();

                  properties.put(PropertyIds.NAME, "My Demo unfiled item");

                  properties.put(PropertyIds.OBJECT_TYPE_ID, "cmis:item");

                  ObjectId itemId = session.createItem(properties, null);

  Map<String, Object> properties = new HashMap<String, Object>();
  properties.put(PropertyIds.NAME, "My Demo unfiled item");
  properties.put(PropertyIds.OBJECT_TYPE_ID, "cmis:item");

  ObjectId itemId = session.createItem(properties, null);

  Item item = (Item) session.getObject(itemId);

  System.out.println((PropertyIds.NAME + ": " + item.getPropertyValue(PropertyIds.NAME )));
  System.out.println((PropertyIds.OBJECT_TYPE_ID + ": " + item.getPropertyValue(PropertyIds.OBJECT_TYPE_ID)));

 }

}

Output

cmis:name: My Demo unfiled item

cmis:objectTypeId: cmis:item

How to create filed item?

Folder interface provides 'createItem' method to create item.

Item createItem(Map<String, ?> properties);

Item createItem(Map<String, ?> properties, List<Policy> policies, List<Ace> addAces, List<Ace> removeAces,OperationContext context);

Below statements create a filed item.

                  Folder folder = (Folder)session.getObjectByPath("/My_Folder-0-0");

                  Map<String, Object>  properties = new HashMap<String, Object>();

                  properties.put(PropertyIds.NAME, "My Demo filed item");

                  properties.put(PropertyIds.OBJECT_TYPE_ID, "cmis:item");

                  Item item = folder.createItem(properties);

  return sessionFactory.createSession(parameters);
 }

 public static void main(String args[]) throws IOException {

  Session session = getSession();
  
  Folder folder = (Folder)session.getObjectByPath("/My_Folder-0-0");

  Map<String, Object>  properties = new HashMap<String, Object>();
  properties.put(PropertyIds.NAME, "My Demo filed item");
  properties.put(PropertyIds.OBJECT_TYPE_ID, "cmis:item");

  Item item = folder.createItem(properties);

  System.out.println((PropertyIds.NAME + ": " + item.getPropertyValue(PropertyIds.NAME )));
  System.out.println((PropertyIds.OBJECT_TYPE_ID + ": " + item.getPropertyValue(PropertyIds.OBJECT_TYPE_ID)));

 }

}

Output

cmis:name: My Demo filed item

cmis:objectTypeId: cmis:item

After running the application, you can able to see the item ‘My Demo filed item’ in work bench by navigating through the folder ‘My_Folder-0-0’.
