# Local Repository

veb[vebjs](../../../tools/vebjs "mention")VEB[vebjs](../../../tools/vebjs "mention")The instantiated factory models can be serialized as text/binary files and saved on a local file system that is directly accessible by digital tools:

* Assets can be saved in .xlsx ([Spreadsheet](../assets/spreadsheet)), [.json](../assets/json), or .owl/.rdf ([ontology](../assets/ontology)) files
* 3D models can be saved in various formats like [.OBJ](https://en.wikipedia.org/wiki/Wavefront_.obj_file) and [.GLTF/.GLB](https://www.khronos.org/gltf/)
* Animations can be saved in [.json](../../animations#schema) and [.txt ](../../animations#animation-sequence)files

## Localhost

If a digital tool needs http(s) communications to retrieve factory models, then a [localhost server](https://en.wikipedia.org/wiki/Localhost) can be launched, e.g. using [JavaScript ](https://www.npmjs.com/package/http-server)or [Python ](https://pythonbasics.org/webserver/)scripts.

The following compressed folder (LocalhostServer.zip) provides an example of localhost server that can be used to load configuration files onto the VEB.js application.
