This article discusses the limitations of traditional BI tools' semantic layers and introduces the Boring Semantic Layer (BSL) as a more pragmatic solution. BSL aims to streamline the process of defining metrics and relationships, making them accessible across various platforms without the complexity of existing tools. It integrates with existing data pipelines and allows for easier governance and multi-modal data access.

The current landscape of semantic layers in data management is fragmented, with numerous competing standards leading to forced compromises, lock-in, and inefficient APIs. As LLMs evolve, they may redefine the use of semantic layers, promoting more flexible applications despite the existing challenges of interoperability and profit-driven designs among vendors. A push for a universal standard remains hindered by the lack of incentives to prioritize compatibility across different data systems.
