Organization URL Lookup

Sometimes, we need to use a URL for an organization as an identifier to find that organization entity. The following query pulls all USGS organizations with official website claims along with an optional "previous address" qualifier that can contain one or more alternate URLs that apply to the organization. These may or may not be active, resolvable URLs but can show up as references.
