You probably want the incoming events to all be flagged with a specific category or categories. This can be useful for filtering.It makes it easier to include the calendar collections imported by the sync engine. Before carrying out the following steps ensure these categories are created.
For public events there are a few more options available when subscribing.
Process Locations and Contacts: This causes locations and contacts to be moved into x-properties "X-BEDEWORK-LOCATION" and "X-BEDEWORK-CONTACT". The receiving end (bedework) may carry out further actions to validate the location or contact and as a result may set a preexisting location or contact in the event. The x-property is always available for display but this process allows the system to validate the location/contact.
Process categories: This does the same for categories.

The actual location will be stored in an x-property
