The Journal Observatory prototype is a proof-of-concept demonstrator which integrates journal information from diverse open data sources including DOAJ, Sherpa Romeo and others, as well as directly from publishers. It shows the power of combining information from these different sources to support three primary use-case areas: open access publishing, preprinting and peer review procedures. By making this information available, we support researchers, publishers, funders and research institutions to make informed decisions and monitor compliance. The prototype comes both with interfaces for programmatic access and with a user-friendly web interface for humans. Programmatic access is available through a SPARQL endpoint and a REST API, while the Journal Observatory Browser serves as the web interface for humans.
In November 2026, we decided to discontinue the hosting of the Journal Observatory prototype, including its SPARQL and REST API endpoints. To ensure continued access to the project's outputs, all source code used to create and deploy the Journal Observatory prototype remains openly available on GitHub, together with the relevant documentation.
The source code used for collecting, converting, unifying, and aggregating journal information from various data sources using the Scholarly Communication Platform Framework is available in this GitHub repository.
The source code for creating and deploying the SPARQL endpoint and REST API that provide programmatic access is available in this GitHub repository.
The source code for creating and deploying the Journal Observatory Browser that provides the web interface for humans is available in this GitHub repository.
