From the mail bag:
"I work with the Citywide Data Warehouse group in DC Government. I noticed your site links to our webpage under Government links; however, it is listed as CapStat. Our group has been renamed to Citywide Data Warehouse since you first posted this. There is a new CapStat page at http://capstat.oca.dc.gov/.
Although we are not currently receiving data from the DCRA Vacant Property group, our Office of Tax & Revenue Registered Vacant Property dataset may assist you when reporting on properties throughout the District. The data catalog is available at http://data.octo.dc.gov/.
If we can be of any assistance, please don’t hesitate to contact our team at CityDW@dc.gov.
