Property

Property is a client-side web application for aggregating open data about properties in the City of Philadelphia. All logic is in client-side JavaScript -- there is not server-side components outside of the open data APIs.

Property makes several AJAX calls, some of which are required to complete before the next one can happen. The flow happens like this:

1. Geocode user input expecting zero or more property results. These results include a summary of OPA and standardized address data.
2. With the OPA number, fetch the OPA details for a single property.
3. At the same time, use the Standardized Address to fetch the service area data from Socrata.

But a user can also share a link directly to a property which contains the OPA number in the query string. In this case, the flow happens like this:

1. With the OPA number, fetch the OPA details for a single property.
2. After the details have been fetched, then use the Standardize address to fetch the service area data from Socrata.
