Building Blocks
Building blocks are small pieces of functionality, you can use them to execute specific actions to, for example, SharePoint. You can add new pages, add new lists, add new items to this list, add a new logo, add or change permissions, add ADMs, and so on. Building blocks are no more than methods which are installed by default in the objects repository of the framework.
All methods of those objects are DLL methods. They all reference Ometa.Utilities.Client.dll in the interface script. If you're developing a custom DLL and want to use a building block you can also reference this DLL file.
Tip
Did you know that you can develop your own building blocks if you have C# knowledge?
