California Database Catalogs 2016 | Electronic Frontier Foundation

"These catalogs are useful to public in a number of ways. For open data advocates, the new law—S.B. 272—represents an important step forward to releasing government datasets, since these catalogs also serve as a sort of menu of records that may be requested under the California Public Records Act, depending on the sensitivity of the data. From a privacy perspective, these catalogs also reveal the types of information that local governments are collecting on their systems, including potentially surveillance equipment and software."
