Episciences implements the Open Science Lens Enhancer

Automated linking at Journal web site


EOSC-DIH business pilots in practice

Challenge & Scenario

The Episciences repository aims to enrich the information provided to the end users, by integrating information available in the OpenAIRE Research Graph, for the Open Science artifacts it hosts. The information is retrieved on demand and contains the most updated information available to facilitate further exploration by the end user. The information enhancement is easily accessible for the end user and does not require extensive, intrusive changes in the repository structure and layout.

Solution & Implementation

Facilitating the integration scenario and use case requirement, the Open Science Lens expanded its operation on integrating sites. A no-code approach enables fine grained, configuration-based control over the web page that hosts Open Science artifacts. This approach enabled pattern based discovery, configurable handling of web page structure and text, extraction of information from unstructured text as well as control over the end result presentation.


After the successful integration of the Open Science Lens Enhancer with the repositories, Episciences now offers to users the ability to explore the wealth of the Open AIRE Research Graph, directly linked to the presented Open Science outcomes. The experience is integrated in a way that  it feels like a website native feature.
A great opportunity to work with the OpenAIRE Graph and EpiSciences to integrate, validate and enrich the Open Science Lens Enhancer.

In depth description


In the context of the EOSC-DIH, one of the objectives for Open Science Lens business pilot was to further explore the Open Science Lens Enhancer integrations capabilities and minimize the Enhancer footprint on the integrating website. The Enhancer already offered a low-code integration pipeline, where custom html attributes could be used to guide the enhancer to identify Open Science artifacts within a web page to retrieve and present the additional information. Extending on that capability, a no-code pipeline was implemented facilitating a rule-based approach through external configuration to navigate, identify, extract and present the points of interest for the Enhancer.

To validate and showcase this functionality, but also to further promote the OSL Enhancer, an integration with the Episciences repositories was implemented. In coordination with Episciences, the information that should be enriched was identified across the different views and layouts of the repositories. A new OSL Enhancer registration was created and Episciences web pages injected the Javascript module required for the Enhancer to operate. The needed rules, locations and patterns were configured using the OSL Configuration Builder available within the OSL Registration Management web application and the displayed information was fine tuned along with the repository owners.

The process of the integration served to further validate the Enhancer integration process and the desired expressiveness of the rule based configuration enhancing pipeline.
Building on the experience gained with the integrations already achieved, Open Science Lens is ready to welcome more use cases and integrators following an assisted process to ensure a streamlined and successful result. In a nutshell, the integration process includes:
  1. Contacting CITE ( to get your license to use the enhancer.
  2. Modify your page to include the Enhancer plugin by adding a small Javascript module import.
  3. Optionally include custom markup to refine how the Enhancer integrates with your site.
  4. Optionally define patterns and rules to locate, extract and present the desired information within your web pages, without modifying your web site.
Service in focus


Episciences is an overlay journal platform that allows researchers to early share openly their research work as a preprint, communicate with the research community their ideas and discoveries, get feedback and claim ownership. The journals hosted by the Episciences platform are diamond open access journals, they adhere to the FAIR principles (Findable, Accessible, Interoperable, Reusable). Researchers save time, money, and effort, and can focus only on their research. The preprints are hosted by open repositories such as arXiv, HAL, Zenodo and are broadly available to the research community.
