The City and County of San Francisco has a new open data site:
Please follow the link to the site to search, browse and view San Francisco data.

An excellent ingredient for innovation would be a dataset of San Francisco entertainment venues. Including but not limited to: music venues, live drama theaters, dance clubs, movie theaters, bars permitted to host live music, etc.

The city's various departments (Planning, Fire, Police, Entertainment Commission, restaurant licensing) administer a number of permits: Club Permit, Place of Entertainment permit, Dance Hall Keeper permit, Cabaret permit, Extended-Hours/After-Hours permit, liquor license, restaurant inspections etc. Venues also have a certain attendance capacity.

Ownership and venue names change often so a live dataset would help. Also, the current status of various venues are in flux due to violations and permit revocations.

This data could then be mashed up in various ways: maps of show listings, event planning resources for producers/musicians/actors, tourist guides, etc. Considering that a large portion of entertainment revenue comes from non-residents, this dataset would stimulate business in SF.

DataSF is a clearinghouse of datasets available from the City & County of San Francisco. Our goal in releasing this site is:
(1) improve access to data
(2) help our community create innovative apps
(3) understand what datasets you'd like to see
(4) get feedback on the quality of our datasets.
