[Projects](https://knowledge.bigenius-x.com/application-modules?hsLang=en#projects) # Understand the Project Metadata Repository content When you [**create a Project**](https://knowledge.bigenius-x.com/create-a-project?hsLang=en) in a Solution, a **default structure is created** in the Metadata Repository. Once you create objects and push them into the Metadata Repository, additional folders or files will become available. **The data are stored in YAML** files with the .yml extension. YAML is **a human-readable data-serialization language commonly used for configuration files and in applications where data is stored or transmitted**. It targets many of the same communications applications as Extensible Markup Language (XML) but has a minimal syntax that intentionally differs from Standard Generalized Markup Language (SGML). ### Metadata Repository content The Metadata Repository is made of 6 main elements: ![](https://knowledge.bigenius-x.com/hs-fs/hubfs/image-png-Oct-12-2023-12-38-33-6138-PM.png?width=149&height=230&name=image-png-Oct-12-2023-12-38-33-6138-PM.png) #### Artifacts folder The artifacts folder contains the last pushed version of the generated artifacts. Please take a look at [Push the generated artifacts to repository](https://knowledge.bigenius-x.com/push-the-generated-artifacts-to-repository?hsLang=en) for more details. #### Discoveries folder The Discoveries folder contains Discoveries files: - One folder per Source System, for example: ![](https://knowledge.bigenius-x.com/hs-fs/hubfs/image-png-May-15-2024-01-12-05-5950-PM.png?width=301&height=76&name=image-png-May-15-2024-01-12-05-5950-PM.png) The Source System folder names correspond to the Source System internal ID, which uses a GUID format. You can find the mapping in the project.yml file, for example, here: ``` .........sourceSystems:  - id: '8a0eb781-b105-4839-9fb8-5be73725b6ee'    name: 'Adventure Works - Sales'    description: 'This is the Source system for the Adventure Works database - schema Sales'    sourceSystemTypeId: 'f69491d8-eed8-43a0-89f9-60195b3415c2'    activeDiscovery: '1137728b-b1c4-417d-8061-82c1b88d3ec2'  - id: '72f7f847-c208-4711-aa7e-f67e394d491e'    name: 'CRM_Example'    description: ''    sourceSystemTypeId: 'f69491d8-eed8-43a0-89f9-60195b3415c2'    activeDiscovery: '243d9fa3-eab7-4c86-a76f-c035167ba9cc'......... ```   - In each Source System folder, the corresponding Discoveries are stored in a YAML file: ![](https://knowledge.bigenius-x.com/hs-fs/hubfs/image-png-Mar-29-2023-12-33-32-6631-PM.png?width=151&height=127&name=image-png-Mar-29-2023-12-33-32-6631-PM.png) Please refer to the [Understand the Discovery YAML file content](https://knowledge.bigenius-x.com/understand-the-discovery-yaml-file-content?hsLang=en) for more details. #### Model objects folder The Model Objects folder contains model objects files: - There is one folder per **Model Object Layer,** for example:![](https://knowledge.bigenius-x.com/hs-fs/hubfs/image-png-Mar-29-2023-02-09-11-7801-PM.png?width=260&height=131&name=image-png-Mar-29-2023-02-09-11-7801-PM.png) - In each Model Object Layer folder, the **Model Object** YAML files are stored: ![](https://knowledge.bigenius-x.com/hs-fs/hubfs/image-png-Mar-29-2023-02-08-59-2523-PM.png?width=294&height=148&name=image-png-Mar-29-2023-02-08-59-2523-PM.png) Please refer to the [Understand the Model object YAML file content](https://knowledge.bigenius-x.com/understand-the-model-object-yaml-file-content?hsLang=en) for more details. #### Config file details The **config.yml** file contains the Project's custom generator configuration. Please refer to the [Understand the Config YAML file content](https://knowledge.bigenius-x.com/understand-the-config-yaml-file-content?hsLang=en) for more details. #### Project file details The **project.yml** file contains the project settings. Please refer to the [Understand the Project YAML file content](https://knowledge.bigenius-x.com/understand-the-project-yaml-file-content?hsLang=en) for more details. #### View file details The **view.yml** file contains the view settings (Dataflow Modeling Views and Relationship Modeling Views). Please refer to the [Understand the View YAML file content](https://knowledge.bigenius-x.com/understand-the-view-yaml-file-content?hsLang=en) for more details.   - [Getting started](https://knowledge.bigenius-x.com/getting-started?hsLang=en#main-content) -
