# Network templates

For each resource type (node, link, network), a template defines the name, icon to be used (nodes) or line style (links), as well as attributes. In the case of the "network" (i.e., the network as a whole, not specific nodes and links), "resources" may be added to represent arbitrary groupings of global attributes for the network.

Templates are matched with models: a template should describe (at least) the input and output expected by a core model. A network defined by a particular template may be used by one ore more models. A model might also use more than one template, but this might be more restrictive, as a model's input requirements are typically fixed; any variation on a template would need to consider this.

## Types

Under construction.

## Attributes

Under construction.

For each attribute (variable), a template further defines the following:

* Data type (*scalar*, *timeseries*, etc.)
* Dimension (*volume*, *flow rate*, etc.)
* Units (*cubic meters*, *cubic meters per second*, etc.)
* Scope (whether or not the attribute is an input or output)
