Refinitiv-Data vs Refinitiv-Dataplatform

in Refinitiv Data Platform

Hi I'd like to know the difference between these libraries:

https://pypi.org/project/refinitiv-data/

https://pypi.org/project/refinitiv-dataplatform/

Is refinitiv-data a library that includes all the features of dataplatform? I'm also having trouble creating a session with refinitiv-data.

Thanks,

    Hi @cmarks

    refinitiv-data is the replacement for refinitiv-data-platform

    refinitiv-data-platform was an alpha release and refinitiv-data is a beta release.

    We will be publishing tutorials and examples soon for refinitiv-data

    The RD Library product owner will also be issuing a statement in the near future explaining the differences in terms of positioning, support etc

    Hi @cmarks

    Hopefully towards the end of next week - for both the above...

    Ok that's great. I'd like to begin using refinitiv-data if possible, it has a simple async function for data in fundamental_and_reference.Definition. I'm still having trouble connecting. This is my attempt to open a desktop session, but any endpoint would do.

    import refinitiv.data as rd
    import refinitiv.data.session as sess

    sess.desktop.Definition(app_key='your_app_key').get_session()
    rd.open_session(app_key='your_app_key')

    Hi @cmarks

    Assuming you have Eikon or Workspace running, the following works fine for me with the latest beta release - refinitiv-data · PyPI v1.0.0b4

    import refinitiv.data as rd
    from refinitiv.data import session
    APP_KEY = '<my app key>'
    rd.open_session(app_key = APP_KEY)

    # outputs

    <refinitiv.data.session._desktop_session.Definition object at 0x278feee7 {name='default-session'}>


    Is that what you are after?

    My Eikon is running and my app key is enabled. I was using an older version, just updated but its still not working. This is the session object I get

    <refinitiv.data.session._desktop_session.Definition object at 0x23a52f3d430 {name='default'}>

    And it says there was a response on port 9000, then it chooses a non working port?

    I get this error when trying to query data:

    res=fr.Definition(['AAPL.O'],['TR.CompanyName']).get_data()
    print(res.data.raw)

    Figured it out, my desktop app didn't have APIPROXY service running. Platform sessions work fine.

    Hi @cmarks

    FYI - we have pushed the first beta release of tutorials and examples to GitHub - Refinitiv-API-Samples/Example.DataLibrary.Python: Example projects and Tutorials demonstrating access to the Refinitiv Data Platform using the Refinitiv Data Library for Python (github.com)

    They have been tested with refinitiv-data · PyPI v1.0.0b6

    NOTE: The links on the README pages for the Dev Portal tutorials/Quick Start etc won't work as we have not published those yet - hopefully be there next week or in the New Year....
