eLTER PLUS Deliverable D4.1 Workflow for retrieval and harmonisation of legacy data

The report summarises the work done with respect to define and prototype workflows for the retrieval and harmonisation of legacy data. It specifically focuses on priority variables defined by the eLTER SO and aims to support Research Challenge related Science Cases at both, site and network scale. The first section describes the context of the work done, also in relation to the ‘Information Clusters’ concept, which aims to enhance findability and accessibility of relevant data sources in the eLTER context. The second section lists identified relevant data sources relevant in this context and provides demonstrators for data retrieval and harmonisation in the third part. We finally discuss and provide recommendations for the eLTER Information Clusters that focus on thematic prioritisation, structural and legal interoperability as well as outline next steps for the implementation. The annexes provide detailed information shown in the report only in aggregated format.
