Almost, but you need a separate scope (thing between braces)
for each link, e.g.:
refinement.pdb_interpretation.apply_cif_link {
data_link = NAG-ASN
residue_selection_1 = chain A and resname NAG and resid 900
residue_selection_2 = chain A and resname ASN and resid 329
}
refinement.pdb_interpretation.apply_cif_link {
data_link = NAG-NAG-b-D
residue_selection_1 = chain A and resname NAG and resid 901
residue_selection_2 = chain A and resname ASN and resid 900
}
Or alternatively:
refinement.pdb_interpretation {
apply_cif_link {
data_link = NAG-ASN
residue_selection_1 = chain A and resname NAG and resid 900
residue_selection_2 = chain A and resname ASN and resid 329
}
apply_cif_link {
data_link = NAG-NAG-b-D
residue_selection_1 = chain A and resname NAG and resid 901
residue_selection_2 = chain A and resname ASN and resid 900
}
}
