This GCN article suggests that OMB is seriously considering utilizing FPDS-NG to deliver the datababse of federal grants spending.
Even though all three databases have their flaws, most government officials believe that, with a few tweaks, FPDS-NG is the best place to start for the new database.
Clay Johnson, OMB deputy director for management, said the procurement side is in much better shape than the grants data, and although he did not offer a total endorsement for starting out with FPDS-NG, he noted that OMB will “not be creating this from scratch.”
“The feeling is most of the data exists,” Johnson said after a press briefing. “It may not exist in the form and level of detail it needs, and it may exist in some agencies but not with others.”
