first encoded data slice eds 1 _ 1 the second row of x 21 x 24 corresponds to a second encoded data slice eds 2 _ 1 the third row of x 31 x 34 corresponds to a third encoded data slice eds 3 _ 1 the fourth row of x 41 x 44 corresponds to a fourth encoded data slice eds 4 _ 1 and the fifth row of x 51 x 54 corresponds to a fifth encoded data slice eds 5 _ 1 note that the second number of the eds designation corresponds to the data segment number in the illustrated example the value x11 ad1 bd5 cd9 x12 ad2 bd6 cd10 x53 md3 nd7 od11 and x54 md4 nd8 od12 returning to the discussion of fig3 the computing device also creates a slice name sn for each encoded data slice eds in the set of encoded data slices a typical format for a slice name 80 is shown in fig6 as shown the slice name sn 80 includes a pillar number of the encoded data slice e g one of 1 t a data segment number e g one of 1 y a vault identifier id a data object identifier id and may further include revision level information of the encoded data slices the slice name functions as at least part of a dsn address for the encoded data slice for storage and retrieval from the dsn memory 22 as a result of encoding.
