In the {{IMSMANG}} information model, items are the containers for core data, such as mine action data. An item is an area, activity or event that a programme records information about and stores in {{IMSMANG}}. There are six categories of items, which are described in the table below. Each category can be characterized characterised by a type that reflects whether the item is designed to track process or activity information or the object or product of an activity.

Additionally, information managers can customise the subcategories so that unused subcategories can be removed and other subcategories added. The same is true for all top-level items within {{IMSMANG}}, which lets information managers specify their exact information model, including the relationships among item categories, and adjust the model as their needs change over time. To accurately map the information model for a programme, it’s helpful to evaluate the available item subcategories and determine if changes to the information model in {{IMSMANG}} are required. While these values can be customized customised after system setup, understanding the types of information for each item is critical to implementing an effective workflow in {{IMSMANG}}. Table 5 shows examples of the possible subcategories of {{IMSMANG}} items.
Two fundamental decisions to make when customizing customising {{IMSMANG}} is to decide what country structure level locations will be consistently linked to and what concept locations will represent. Typical concepts that a location is used to represent include:
