At REVSYS, our first attempt at adding JSON-LD to our sites relied on embedding the data in the Django template. For the most part, this has worked fine, and we've had good results from an SEO perspective. But in terms of maintainability, it has not been the most efficient approach. We have now started transitioning to generating the structured data using Django Ninja and Pydantic. As a result, we now have cleaner templates and better maintainability.
