Meeting objectives: 

The Research Metadata Schemas Working Group has planned three tasks when started: 1) Guidelines for publishing structured metadata markup,  2) A generic conceptual data model and 3) Toolings for supporting the publishing process. The group has delivered two outputs to support the first two tasks in the past  two years. On that context, our objectives of this session include: 

Meeting agenda: 

Collaborative session notes:

  • (15 mins) intro to the group and the two outputs

  • (40 minutes) Invited lightning talks (candidate speakers, to confirm when a breakout slot is allocated)

    • Polar Pilot Federated Search (from WDS-ITO: Melinda Minch/Chantelle Verhey); 

    • Common Metadata Framework – extending the Crosswalks to Mobilize Computable Biomedical Knowledge (Brian S. Alper, Computable Publishing LLC, Scientific Knowledge Accelerator Foundation) 

    • CCADI to talk about their metadata mediator/semantic mediator (tooling built to mediate between various schemas through crosswalks created by the CCADI team -- and used our crosswalks to jump off from) (Rebekah Ingram)

    • A mapping process for RDF data from different data models/ontologies to using SPARQL CONSTRUCT queries (Tobias Schweizer, SWITCH)

    • Cross-domain linguistic extensions for data model schema ontology crosswalks using open-source tools for creating machine-actionable version controlled collections (Lindsey Anderson, PNNL).

  • (25) Discussion:

    • Adoption of the outputs, experience exchange  from implementation/consumption of structured data

    • Toolings for facilitating crosswalks and the publishing process

  • (10 minutes) Summary and Closing remarks

Target Audience: 
  •  Anyone (especially data repository/catalogue manager/developer/operator) who is interested and would like to know more about how to publish and get their data discoverable via the web architecture.

  • Anyone who is interested in developing tools to facilitate crosswalks and the publication of structured metadata.

  • Anyone who is interested in building knowledge graphs or any innovative data discovery applications on aggregated research data resources.

Brief introduction describing the activities and scope of the group: 

This working group provides a platform to complement, build on and extend efforts from, and the like communities in applying and extending the core vocabulary for describing research datasets and related resources. 

The outputs include: 

  • A generic ‘conceptual data model’ with essential types and properties for research data discovery over the web. The model will be built on,,, DCAT, DDI-DISCO and SSN schemas from some representative research domains, and data discovery use cases. A research domain can map their schema to the conceptual model when they publish data to the web or exchange metadata between data portals/repositories.

  • Guidelines of common patterns for publishing metadata landing pages with structured data markup, and guidelines of how to customise the research schemas for targeted domains with examples.

  • Toolings for making the implementation easier if resources are available. This could include collecting and cataloguing tools that generate, validate and parse & DCAT markup, etc. 


Short Group Status: 

The Research Metadata Schema Working Group was endorsed in Sept. 2019. The WG had been working and delivering two outputs before it became a maintenance group in late 2021.
