Properties are a subset of the organization. They are used to group a collection of adapters for the purpose of assigning common access rights to them. For example if your organization is Middlefield University you might have a property for the LMS. This property would include adapters for all the third-party tools that plug in to your LMS. Then not only could you assign your LMS admin to work within this property but you can even invite the LMS vendor to participate as well.
