List of URIs corresponding to the rows (1st dimension) of the coupling matrix. If not all indices of a given node are used, they must be listed explicitly e.g. rows_uri(i) = pf_active:1/coil(i) will refer to a list of indices of the occurrence 1 of the pf_active IDS of this data entry. If the rows correspond to all indices of a given vector, it is sufficient to give a insgle uri, the one of the vector with the impliicit notation (:), e.g. rows_uri(1) = /grid_ggd(3)/grid_subset(2)/elements(:).

Path of the grid, including the IDS name, in case of implicit reference to a grid_ggd node described in another IDS.
