These are research notes from my exploration of NYC-DB data.
See the NYC-DB schema document for details on the schema.
A nice description of the ACRIS dataset is available in the fitnr/acris-download README. Also useful are the ACRIS Document Control Codes (PDF).
I found that querying some of the tables in this dataset took a long time so I filed aepyornis/nyc-db#56.
The JustFix.nyc Tenants App uses this dataset to figure out who a tenant's landlord is. See the nycdb
directory on JustFixNYC/tenants2 for more details.
See the PLUTO data dictionary PDF for lots of details.
