Items are entered into {{IMSMANG}} by means of a Data Entry Form. Typically, each category of items has its own Data Entry Form template for recording information specific to that category. When entered into {{IMSMANG}}, all Data Entry Form items must be assigned to a Location, which is tied to the country’s gazetteer, or political or administrative structure. The items can then be traced back to the Country Structure so that users can easily report data such as the number and size of hazardous areas within a particular province.

Part of defining and documenting an information model includes defining the useful information attributes for each {{IMSMANG}} item. {{IMSMANG}} comes with more than 1,000 [[Information Classification | data fields already defined]] as well as the capability to create additional custom-defined fields (CDFs). This makes it important to critically assess which data fields are useful to a programme for decision-making, analysis and reporting and to focus on those while ignoring data fields that don’t provide additional value. Limiting information to only that which is useful to the programme provides long-term benefits including reducing the data collection and data entry burden and improving system performance. And, while many data fields may be collected for each {{IMSMANG}} item, some fields may be more important for analysis than others. For example, whether a victim has been injured or killed may be more important for analysis than the victim’s nationality.

As subsequent information is collected about a specific attribute of an item, {{IMSMANG}} updates the item’s Summary on an attribute-by-attribute basis. The calculation of the Summary is done based on '''Date of Information''' and therefore it is important that Date of information is reflecting the age of the information and not the date of entry into {{IMSMANG}}.

The result is one Land whose information is updated over time by the three Activities linked to the land. This way to track information can be used to represent the information management process and status rules accurately for a Land Release, Risk management or other process model.

Although any item can be linked to any other item, not all relationships necessarily make sense for every implementation. The diagrams below describe some of the more common logical relationships among items and can serve as the basis for an information model when implementing {{IMSMANG}}.
