Interoperability Framework for Exchanging Information.

Learn more about the links between scholarly literature and data.
Overview

ScholeXplorer is OpenAIRE's Scholix hub.

ScholeXplorer populates and provides access to a graph of links between dataset-literature objects and dataset-dataset objects. Links (and objects) are provided by data sources managed by publishers, data centres, or other organisations providing services to store and manage links between data sets and publications.

How does ScholeXplorer work?

The process in 3 steps!

01

Expose Scholix data

ScholeXplorer harvests scholarly links from OpenAIRE-compatible data sources, attempting to resolve metadata regarding related PIDs.

Data sources that want their published or provided links to be included in ScholeXplorer must be registered as a valid OpenAIRE repository.

02

Access Scholix data from this hub

The Scholix Swagger API allows clients to run REST queries over the ScholeXplorer index in order to fetch links matching given criteria. In the current version, users can search for:

  • Links whose source object has a given PID or PID type;
  • Links whose source object has been published by a given data source ("data source as publisher");
  • Links that were collected from a given data source ("data source as provider").

The latest API is available from here.

The results of queries return lists of links encoded as JSON Scholix records. JSON (and XML) schema and example records for Scholix links are available on GitHub.

03

Terms of Use and SLA

REST APIs: ScholeXplorer's REST APIs are free-to-use (no sign-up needed) by any third-party service.
Please note that:

  • The service limits each query to around 10,000 paged results (pages are by default 100 results in length and can be navigated via resumption token)
  • Since March 2018 a full JSON dump of the service is made available in Zenodo.org every six months
  • For unlimited access to the APIs please contact the service administrators

Metadata license is CC-BY: Scholix metadata records returned by the service can be freely re-used by commercial and non-commercial partners under CC-BY license, as long as OpenAIRE ScholeXplorer is acknowledged as a content provider.

SLA: The service is running in production 24/7 within the OpenAIRE infrastructure premises deployed at the data centre facilities of the Interdisciplinary Centre for Mathematical and Computational Modelling (ICM).
