By default, the Property View in Maltego can be found in the bottom right-hand corner of your Maltego client. The properties of an entity are used by transforms and are passed along with the entity’s value to the transform. Detail View information is not passed to the transform. Unlike the Detail View, information in the Property View can be edited by the user after the information has been returned from a transform.
The Property View of an entity is in three sections, namely the Properties, the Dynamic Properties and the Graph Info.
Under the Properties heading you will find the default properties for an entity. These properties are inherent to the entity type and will be included when a new entity is manually added to your graph from the Entity Palette.
Dynamic Properties of an entity are properties that are added to the entity by the transform that returns the entity. These properties are specific to the transform that created the entity and will not appear in a new entity that is added from the Entity Palette.
The Graph Info includes meta information about the entity that you currently have selected.
