Rich Context API integrations for federating discovery services and metadata exchange across multiple scholarly infrastructure providers

Project description


Rich Context API integrations for federating discovery services and metadata exchange across multiple scholarly infrastructure providers.

Development of the Rich Context knowledge graph uses this library to:

  • identify dataset links to research publications
  • locate open access publications
  • reconcile journal references
  • reconcile author profiles
  • reconcile keyword taxonomy

This library has been guided by collaborative work on community building and metadata exchange to improve Scholarly Infrastructure, held at the 2019 Rich Context Workshop.



To install from PyPi:

pip install richcontext.scholapi

If you install directly from this Git repo, be sure to install the dependencies as well:

pip install -r requirements.txt

Then copy the configuration file template rc_template.cfg to rc.cfg and populate it with your credentials.

NB: be careful not to commit the rc.cfg file in Git since by definition it will contain sensitive data, e.g., your passwords.

Parameters used in the configuration file include:

parameter value
chrome_exe_path path/to/chrome.exe
core_apikey CORE API key
dimensions_password Dimensions API password
elsevier_api_key Elsvier API key
email personal email address
orcid_secret ORCID API key
repec_token RePEc API token

Download the ChromeDriver webdriver for the Chrome brower to enable use of Selenium. This will be run in a "headless" mode.

For a good (though slightly dated) tutorial for installing and testing Selenium on Ubuntu Linux, see:


from richcontext import scholapi as rc_scholapi

# initialize the federated API access
schol = rc_scholapi.ScholInfraAPI(config_file="rc.cfg", logger=None)
source = schol.openaire

# search parameters for example publications
title = "Deal or no deal? The prevalence and nutritional quality of price promotions among U.S. food and beverage purchases."

# run it...
if source.has_credentials():
    response = source.title_search(title)

    # report results
    if response.message:
        # error case


First, be sure that you're testing the source and not from an installed library.

Then run unit tests on the APIs for which you have credentials and generate a coverage report:

coverage run -m unittest discover

Then create GitHub issues among the submodules for any failed tests.

Also, you can generate a coverage report and upload that via:

coverage report
bash <(curl -s -t @.cc_token

Test coverage reports can be viewed at

API Integrations

APIs used to retrieve metadata:

See the coding examples in the unit test for usage patterns per supported API.


  • ChromeDriver

If you encounter an exception about the ChromeDriver version, for example:

selenium.common.exceptions.SessionNotCreatedException: Message: session not created:
  This version of ChromeDriver only supports Chrome version 78

Then check your instance of the Chrome browser to find its release number, then go to to download the corresponding required version of ChromeDriver.
