What is a .XMI file?
The core fact is that a .XMI file usually stores an XML Metadata Interchange File. The Object Management Group created this standard to help programs exchange metadata. Developers use these files to share Unified Modeling Language (UML) models and system designs between different software tools.
However, the .XMI extension has multiple possible meanings. It can also be an Extended MIDI music file used by the Miles Sound System in classic video games. Additionally, it might represent an IBM Mainframe TSO TRANSMIT dataset or a visualization metadata index file for Siemens Teamcenter.
How to open .XMI files?
If you have a standard XML Metadata Interchange File, you can open it with UML modeling software. Popular options include StarUML, the Eclipse Modeling Framework, and enterprise tools from SAP.
For Extended MIDI audio files, you need an older audio application like XMI Player. For IBM mainframe files, system administrators use specific mainframe data extraction tools.
Because the extension is used for completely different things, viewer.online/xmi analyzes .XMI files to identify their exact format and creator software, shows which programs can open the file, and usually previews it.
Summary
Because most .XMI files use the known XML format, viewer.online/xmi can safely open and display them online, eliminating compatibility problems.
