# Assets

Assets are basic elements composing a model, e.g. physical objects like machine tools, parts, conveyors, buffers, but also processes and plans.

Assets can be defined according to an instantiation workflow consisting of the following steps:

* [spreadsheets](/vlft/kb/instantiation/assets/spreadsheet.md)
* [.json files](/vlft/kb/instantiation/assets/json.md)
* [OWL ontology](/vlft/kb/instantiation/assets/ontology.md)
