The package is used to define asset-level models for objects. Assets may be comprised of other assets and may have relationships to other assets. Assets also have owners and values. Assets may also have a relationship to a PowerSystemResource in the Wires model.<br/><br/>TODO: The following has been copied from a very old version of draft Part 11, so the references are wrong, but we store the knowledge here to reuse later:<br/>"Assets are the basic units which define a physical infrastructure. PowerSystemResources are logical objects meaningful to operations which are constructed from one or more Assets, although PowerSystemResources are not required to specifiy their component Assets.<br/>The Asset package is comprosed of several packages. The key concepts of an Asset are as follows:<br/><ul>
<li>Assets can have names, through inheritance to the Naming package</li><li>Assets are physical entities which have a lifecycle</li><li>One or more assets can be associated to create a PowerSystemResource</li><li>Assets can be grouped (aggregated) with other Assets</li><li>Assets are typically either 'point' or 'linear' assets, which relate to physical geometry</li><li>Assets have a close relationship to Work as a consequence of their lifecycle</li></ul>
The following sections describe the packages in the Assets package.<br/>The AssetBasics package defines the relationship between Asset and other classes, such as Organization, PowerSystemResource and Document.<br/>Point assets are those assets whose physical location can be described in terms of a single coordinate, such as a pole or a switch.<br/>Linear assets are those assets whose physical location is best described in terms of a line, plyline or polygon.<br/>Asset work triggers are used to determine when inspection and/or maintenance are required for assets".<br/><br/>
