Open http://185.23.162.165/. Register as a new user (email checking not done), then create a new project; to start working with Europeana, choose 'Initialize by Europeana example project'. Alternatively, the same project contents can be uploaded after the project creation from this site. A project with BNB Query visualizations is available here. To work with the BNB query environment, start with an empty project, then upload the project into the environment (from the toolbox in the project diagram view). Check out the code to set up the visual query tool locally (Docker-based running options available, as well). |
