Everything stored on the cloud could potentially be a knowledge source used for e-business. Given learners' profiles,
desires and feedback on what they have already learned, a new form of personalized e-business emerges, namely Cloud
collaborative E-business (CeL). CeL should be able to choose from structured to totally unstructured business material but needs
to make them useful for each individual. Existing metadata standards cannot facilitate composition of personalized business
paths as a series of business objects. In this paper, we present the structure of CeL Business Objects (CeLLOs), which include an
additional set of metadata suitable for each phase of CeL development.
