# Local Repository veb[VEB.js](/vlft/tools/vebjs.md)VEB[VEB.js](/vlft/tools/vebjs.md)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](/vlft/kb/instantiation/assets/spreadsheet.md)), [.json](/vlft/kb/instantiation/assets/json.md), or .owl/.rdf ([ontology](/vlft/kb/instantiation/assets/ontology.md)) 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](/vlft/kb/instantiation/animations.md#schema) and [.txt ](/vlft/kb/instantiation/animations.md#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. {% file src="/files/7F3QrXQk52SX5tPetH8b" %} --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question. Perform an HTTP GET request on the current page URL with the `ask` query parameter: ``` GET https://virtualfactory.gitbook.io/vlft/kb/instantiation/datarepo/local.md?ask= ``` The question should be specific, self-contained, and written in natural language.
