 Working groups are focused teams that drive specific areas of the specification forward. Each working group has a designated lead and members drawn from across the participating organizations.
 
-#### 1. Metric Language and Relationships
-
-This group focuses on the expression language for defining metrics, including aggregation semantics, cross-dataset references, and the relationship model that connects datasets. Key areas include advanced metric types (ratios, cumulative metrics, derived metrics) and the rules governing how metrics traverse relationships.

-#### 2. Composability
-
-This group explores how semantic models can be composed from smaller, reusable building blocks — enabling modular model definitions, model inheritance, and layered semantic models that build on top of each other.

-#### 4. Ontology
-
-This group works on the formal ontological representation of semantic models — defining the conceptual framework and vocabulary for describing business entities, their properties, and the relationships between them at a higher level of abstraction.
