EOSC Future grant: Social Science Data Objects in the EOSC Portal


The project created a recommended framework for harvesting and delivering for discovery rich metadata of Social Science Data (SSD) objects for the EOSC Portal Service Catalogue. The project consisted of four primary tasks: 

  1. Identification of generic descriptors in Dublin Core terms, DataCite Metadata Schema and OpenAIRE Guidelines that allow differentiating SSD objects (report)  
  2. Analysis of major data archives to come up with a vocabulary for standardized description of types of social science data objects (report
  3. Metadata fields for detailed descriptions of survey and aggregated SSD data were identified and described (with recommendations for optimal use) 
  4. Description of a prototype showcasing provision of metadata of SSD objects from the LiDA Dataverse Repository, based on a metadata harvesting and discovery framework (report). 

The proposed framework allows enriching generic descriptors of data with relevant additional information depending on the type of the SSD object. This conditional model combines flexibility and comprehensiveness, as its main operating framework would be based on the most widely used generic metadata descriptors while – at the same time – integrating additional elements from domain-specific metadata descriptors.
