### Summary of Changes 1. **Implemented a Versioning System**: - Track changes made to the XML data. - Store different versions of the XML data. - Provide an interface to view and restore previous versions. 2. **Integrated Version Control with User Roles**: - Allow specific roles (e.g., trainers, maintenance operators) to view and restore previous versions. 3. **Enhanced Data Export Functionality**: - Ensure that exporting data includes version history. ### Deployment Steps 1. **Create GitHub repository** and add all files: `index.html`, `styles.css`, `pdf.js`, `editor.js`, `auth.js`, `search.js`, `copilot.js`, `role.js`, `versionControl.js`, `data.xml`, `schema.xsd`, `transform.xslt`, `schema.dtd`. 2. **Create Azure Static Web App** in Azure portal: - Link to the GitHub repository. 3. **Ensure GitHub Actions** are configured to build and deploy the site correctly.
