The Library Concept

Libraries help you to make your BPMN process executable. They contain predefined classes, interfaces, operations and parameters you can use during modeling by simple drag & drop.
Libraries are developed with the Builder. The Designer comes with a standard library which already provides all necessary Base Types.

Using libraries has several advantages for developers:

• You can provide additional data types and operations via libraries.
• You can reuse implementations you have already developed with the Builder.
• You can use libraries for modularization:
  • Implementations can be recycled in various processes via libraries.
    
  • Multiple developers can contribute to the same process implementation by working on different libraries.
• You can add features to the Designer, for example access to backend systems, via libraries.
• You can use different versions of the same library as the library administration allows ver

Library Usage in Designer

As libraries are developed with the Builder, you need to upload them to the Designer to make them accessible in your services.

In the Designer, you upload your libraries to a namespace. This is done in the Libraries section of the Designer administration. The uploaded libraries are then available in all services created in this namespace. How to upload your libraries to the Designer is explained in detail on page Administrating Libraries.

Once a library has been uploaded, you can add it to any service created in this namespace. There are two ways to do so:

• In the Explorer: Open the Libraries folder in your service and use the Manage Libraries button.
• In the BPMN Model: Use the Manage Libraries button in the Service panel.

The Service Panel

The libraries you have added to a service reside in the Service panel.

	If you use the panel preset of the BPMN editor, the Service panel is displayed in the upper left corner of the editor. Multiexcerpt include SpaceWithExcerpt INTERNAL MultiExcerptName tip_panel_management DisableCaching true PageWithExcerpt INTERNAL:_designer_excerpts
	The Service panel gives you direct access to all libraries of your project, and thus to all of your predefined classes, interfaces, operations and parameters. Multiexcerpt include SpaceWithExcerpt INTERNAL MultiExcerptName tip_library_administration DisableCaching true PageWithExcerpt INTERNAL:_designer_excerpts A library can contain the following elements: Icon Name Image Added Package Image Added Class Image Added Property Image Added Interface Image Added Operation Image Added Parameter To expand an element in the tree, click on Image Added. Use Image Addedif you want to collapse a tree below an element.
	Each library element can have a documentation. Hover your mouse on a library element to see if documentation is available. This is indicated by the icon. The documentation is displayed as a tooltip. For easier reading of longer documentation, you can click the icon to see the complete documentation in a pop-up window:

	You can also define your own data types in folder Data Model. You can add your own packages, classes, interfaces, operations, properties and parameters. Tip Go to page Modeling Data Mapping for more detailed information on how to work on your own data model and how to define mappings between data types.
