facilitating storage of the set of metadata slices and the plurality of sets of encoded data slices in one or more storage units of the DSN; and

wherein subsequent accessing of the metadata slices reproduces the metadata and the first data segment of the data object, making the first data segment of the data object available for use by the one or more computing devices while continuing to retrieve the additional data segments from the DSN.
