Scholarly Literature & Data interlinking.

ScholeXplorer is a service that accepts scholarly works metadata information, about publications-data or data-data links, from validated sources.

It enables building and clearing of deduplicated information on the OpenAIRE Graph and provides access to it.


ScholeXplorer is OpenAIRE's Scholix hub.

Back in 2016, OpenAIRE worked closely with the Research Data Alliance (RDA) and the International Council for Science World Data System (ICSU-WDS) to create Scholix. The vision was to create a universal interlinking service and thereby, a multi-hub interoperability framework. Hubs are (existing) services that collect and aggregate information about links from their respective communities. The framework respects existing community-specific practices while enabling interoperability among the hubs by specifying a common information model and open exchange protocols. In 2023, the Scholix WG work was combined with the Open Science Graphs Interest Group (OSG IG).

Why ScholeXplorer.

Every research object possesses hundreds of metadata  information. To enable scholarly works discovery, analysis, management of data, it is necessary to connect and relate, metadata among publications, datasets and other research products. Therefore, populate and enable the creation of a rich graph network with all interconnections and relations.

Interconnection among publications-datasets-other research products
Metadata information is collected and mapped between a source and target object. The process repeats for all research objects.
Deduplication of metadata
ScholExplorer metadata information benefits the OpenAIRE Graph metadata deduplication.
