Listing services within a networked environment

A system comprising:

• one or more processors;
• and
• a memory that stores instructions that, when executed by the one or more processors, configure the one or more processors to perform operations comprising:
• receiving, at a client device, a first user input indicating a selection of an item;
• presenting, at the client device, a first user interface for defining one or more parameters of a notification attribute, the first user interface comprising a location-based trigger option and an event-based trigger option;
• receiving a first selection of the location-based trigger option;
• presenting, at the client device and in response to the first selection, a second user interface including a field configured to receive a threshold distance for generating a location-based notification;
• receiving a second user input indicating the threshold distance;
• receiving a second selection of the event-based trigger option;
• presenting, at the client device and in response to the second selection, a third user interface comprising a calendar that includes a plurality of events selectable to trigger generation of an event-based notification;
• receiving a third user input of an event of the plurality of events;
• providing an indication of the item in association with the threshold distance of the notification attribute and the event of the notification attribute to a remote computing device to update a database entry associated with the item;
• and
• receiving, from the remote computing device, a notification event associated with the item in response to detecting that one or more of the threshold distance of the notification attribute and the event of the notification attribute have been satisfied.

A device-readable storage medium embodying instructions that, when executed by a device, cause the device to perform operations comprising:

• receiving, at a client device, a first user input indicating a selection of an item;
• presenting, at the client device, a first user interface for defining one or more parameters of a notification attribute, the first user interface comprising a location-based trigger option and an event-based trigger option;
• receiving a first selection of the location-based trigger option;
• presenting, at the client device and in response to the first selection, a second user interface including a field configured to receive a threshold distance for generating a location-based notification;
• receiving a second user input indicating the threshold distance;
• receiving a second selection of the event-based trigger option;
• presenting, at the client device and in response to the second selection, a third user interface comprising a calendar that includes a plurality of events selectable to trigger generation of an event-based notification;
• receiving a third user input of an event of the plurality of events;
• providing an indication of the item in association with the threshold distance of the notification attribute and the event of the notification attribute to a remote computing device to update a database entry associated with the item;
• and
• receiving, from the remote computing device, a notification event associated with the item in response to detecting that one or more of the threshold distance of the notification attribute and the event of the notification attribute have been satisfied.
