The Mediation Layer provides community-agnostic functionality for creating high-quality data products. It includes tools for managing metadata, transforming data from a technical data model into a semantic model, and improving data quality.

Zooming into the Mediation Layer

Semantic Web

Our goal is to build services based on well-established, internationally agreed semantic standards spaning both data and metadata. More and more metadata standards are being offered in a Semantic Web compliant format as ontologies. We identified an initial subset of semantic core models, namely: Schema.org and ABCD3. We stored and published their corresponding ontologies on BiodivPortal, our terminology repository and service. Additional standards for data are being collected and similarly stored, like for instance the Ecological Trait-data Standard (ETS).

Our Goals

• • Translation of the physical data model into domain models and vice versa
  • Support of common metadata standards
