An operation associated with an artifact which includes a plurality of fragments is received. A dimension is obtained and a plurality of sub-operations is generated based at least in part on the operation and the dimension where each of the plurality of sub-operations is associated with a subset of values associated with the dimension. The plurality of sub-operations is performed on the plurality of fragments, including by generating, for each of the plurality of fragments, dimensional metadata which includes a subset of values associated with the dimension for that fragment.
