# Term: Multiplicity

In InfoGrid, the term Multiplicity refers to the number of MeshObjects that may participate in a Relationship of a particular RelationshipType with a given MeshObject. Multiplicity is expressed as a range from a minimum number (e.g. 0, or 2) to a maximum number (e.g. 1, 17, or `N`). `N` represents "any number", regardless how large.

Multiplicities are defined in InfoGrid Models where RelationshipTypes are defined.

Examples:

- 1:1 - given the source MeshObject, exactly one destination MeshObject will be found
- 0:5 - given the source MeshObject, between zero and 5 MeshObjects will be found
- 1:N - given the source MeshObject, at least 1 and potentially any number of MeshObjects will be found
