To retrieve LOVs from Siemens Teamcenter, you can utilize the Teamcenter SOA API, which provides services for accessing LOV data. The LOV service in the com.teamcenter.services.strong.core package is specifically designed for this purpose.

While Teamcenter does offer a REST API, its capabilities may not encompass all functionalities available in the SOA API, including LOV retrieval. Therefore, for comprehensive access to LOVs, the SOA API is the recommended approach.

For detailed information on the LOV service and its operations, refer to the official Teamcenter documentation.

If you're integrating with Mendix, you'll need to implement a connector that interacts with the Teamcenter SOA services to fetch the LOV data. Ensure that your integration handles authentication and data parsing appropriately to seamlessly incorporate the LOVs into your Mendix application.

Hope this helps
