A Single Window (SW) is defined in UN/CEFACT Recommendation 33 as "a facility that allows parties involved in trade and transport to lodge standardized information and documents with a single entry point to fulfil all import, export, and transit-related regulatory requirements. If information is electronic, then individual data elements should only be submitted once" (UN/CEFACT, 2005).

Thus, the SW should normally be an "Administration to Business" (A2B) type systems related to international trade and transport, but the term is normally used less restrictive than that. The next section will give a more general overview of the different types of SW and what this part of the MiTS page focuses on.

ISO 28005 as basis for a SW

The ISO 28005 standard is recently completed with two parts:

  1. ISO 28005-1:2013 Security management systems for the supply chain -- Electronic port clearance (EPC) -- Part 1: Message structures.
  2. ISO 28005-2:2011 Security management systems for the supply chain -- Electronic port clearance (EPC) -- Part 2: Core data elements.

These standards supply mechanisms to implement an XML based SW system, covering requirements in the FAL Convention as well as various other reporting requirements.

The Datamodel page contains more infromation abouth this standard.

A SW reference model

The figure shows different types of SW's that have been discussed in the litterature. later sections will give a brief overview of each of them. The reference model is based on a SW taxonomy, using two different criteria to classify SW systems:

  1. Public/Private: If the system is handling public (A2B) or private (B2B) data exchanges
  2. Nautical/Cargo: If the system is handling cargo related or nautical information exchanges.

In addition, two further criteria can be used to define the geographic or integration scope of the SW.

  1. Integration level: Degree of integration, e.g., data transaction only, database, workflow, logic checks, etc.
  2. Geographic scope: Geographic area covered, e.g., terminal only, port only, group of ports, national or international.
SW Reference model

In the figure it is the two first criteria that is used to show some of the possibilities. The geographic range is only visible in the TOS/PCS entry while the integration level is not shown.

"Maritime Single Window"

The Maritime Single window is mainly used for clearance of ships into or out of port for navigational safety and securities purposes. It will have limited facilities for port or terminal logistics, although some services may be included, typically pilot, tug and berth reservation. This is however, most common when these resources are managed by the maritime or port authorities and not private operators or the terminals themselves (Rødseth, Ø.J., Fjørtoft K.E., Lambrou M.A. 2011).
