Summary
In Germanium, the ms.prod and ms.technology metadata attributes will be retired from the Learn platform and consolidating values into ms.service and ms.subservice for reporting on content by product.

• C+E Skilling Content Architecture manages internal, business-facing taxonomies that enable reporting on key metrics for content published on Microsoft Learn. Authors manually apply values from these taxonomies to populate metadata attributes.
• Two of these taxonomies are ms.prod/ms.technology and ms.service/ms.subservice. "ms.prod" and "ms.service" were distinctions carried over from legacy systems that predated the Learn platform, intended to differentiate on-prem products from cloud services.
• In Germanium, we are retiring the ms.prod/ms.technology attributes and migrating metadata to the ms.service/ms.subservice attributes. We plan to rename the attributes from ms.service and ms.subservice in a future semester.

Why are we making this change?

• For the business: Accuracy of reporting metadata directly impacts the accuracy of content analytics, so it's important that related taxonomies reflect the current state of the business. Most product taxonomies within Microsoft no longer distinguish between "on-prem" and "cloud service."
• For content authors: We eliminate the need to choose between two similar attributes when applying reporting metadata to content or filtering reports.
• For engineers, data scientists, and taxonomists: Simplifying and reducing underlying metadata attributes reduces the cost and complexity required to extend metadata capabilities on the platform.
