A field report is a data entry form used to record and store information about an item.

A current view is a summary of all the information collected about an item on field reports.

Reconciliation is the process of assigning the information in a field report to an existing item or creating a new item/current view.

All mine action information is entered into IMSMA^NG via a field report, a data entry form used to collect information about an item. When a field report is completed, it is either reconciled to an existing item (that is, it is determined to be information about an item that already exists in IMSMA^NG) or it is reconciled as new (that is, it is determined to be information about an item that does not already exist in IMSMA^NG).

With this approach, users can collect and store multiple field reports about the same item over time so that the entire history of the item is preserved in the system. The approach also provides a complete audit trail of all changes made to any mine action information so that information managers can answer the question, "What did we know and when did we know it?"

IMSMA^NG also provides a constantly updated current view of the item which represents the sum of information about the item at any given time. As subsequent information is collected about a specific attribute of an item, IMSMA^NG updates the item’s current view on an attribute-by-attribute basis. For example, Field Report #1 collects some initial information about a hazard. It sets the priority to "Medium" and specifies that the hazard contains AP mines and is 25,000 sqm. Field Report #2 updates information about the hazard after a subsequent assessment. The report sets the priority to "High" and specifies the presence of AP and AT mines, but it does not change the size or the status of the hazard. Field Report #3 updates the hazard’s size and status after clearance operations are complete. The figure below shows how the hazard’s current view is updated after all three reports are entered into the system.

Current view calculations are based on the date of the field report, so it is possible to enter data into the system out of chronological order (that is, to collect past information about an item) without disrupting the current view. For example, if a fourth field report were collected and dated between Field Report #1 and Field Report #2, it would have no effect on the current view as all information in the example was updated with Field Report #2 or later.
