Workflows can use objects that you create independently of vRealize Orchestrator as attributes. To use external objects as attributes in workflows, you import them into the server as resource elements.
Objects that vRealize Orchestrator workflows can use as resource elements include image files, scripts, XML templates, HTML files, and so on. Any workflows that run in the vRealize Orchestrator server can use any resource elements that you import into vRealize Orchestrator.
After you import an object into vRealize Orchestrator as a resource element, you can make changes to the object in a single location, and propagate those changes automatically to all the workflows that use this resource element.
The maximum size for a resource element is 16 MB.
You can import, export, restore, update, and delete a resource element.
