OOI Machine to Machine (M2M) Demo

Basic instructions for using the OOI M2M Web Services. See ipython notebooks for examples using python's requests module.

Getting Started

• Create a user account on ooinet.oceanobservatories.org or use the CILogon button with an academic or Google account.
• Log in
• Navigate to the drop down menu screen in the top-right corner menu
• Click on the "User Profile" element of the drop down.
• Copy and save the following data from the user profile: API Username and API Token. The API Username is similar to “OOIAPI-QTULEV9STCAS55”. The API Token is similar to “YXP2Q2W4SOP”.

Tools to access OOI M2M Web Services

python requests

requests.get('https://ooinet.oceanobservatories.org/api/m2m/...', auth=(API USERNAME, API TOKEN))

curl

curl –k https://API USERNAME:API [email protected]/api/m2m/...

httpie

http --auth API USERNAME:API TOKEN https://ooinet.oceanobservatories.org/api/m2m/...

Running the Notebooks

• create a python virtual environment and start the notebook from inside

conda create -n m2m_demo python=2.7 anaconda

source activate m2m_demo

pip install xarray==0.9.0

pip install netcdf-python

pip install thredds-crawler

jupyter notebook

source deactivate

(The latest xarray gives an error, seems a known issue which was fixed in future versions, but for now downgrading to 0.9.0 pydata/xarray#1775)
