To operate legally in District of Columbia, most businesses must get a basic business license from DLCP. The BBL groups licenses by the type of business activity and regulatory approvals required. After May 14th, the updates will show attribution changes that you should be aware of. Several fields that are no longer relevant will be removed. If you have built web apps using Open Data DC's layer or call DC GIS map services directly, you may need to make a modification.
