Watson Studio Gallery project for the [TODO-add-dataset-name] data set

Getting started

• Open https://github.com/CODAIT/watson-studio-gallery-dax-project-template

• Click Use this template and create a new dataset project repository in https://github.com/CODAIT/ naming it watson-studio-gallery-XXX-project replacing XXX with the data set short name.

• Create an issue in https://github.com/CODAIT/DAX-Datasets/issues/new/choose tracking development/publication progress

• Add a link to the newly created project in this status document.

• Review the content of this sample project https://dataplatform.cloud.ibm.com/exchange/public/entry/view/a7432f0c29c5bda2fb42749f363bd9ff to familiarize yourself with the typical content of a DAX project:

  • Description
  • README
  • Data assets
  • Notebooks

  The source for this project is located here: https://github.ibm.com/CODAIT/watson-studio-gallery-dax-weather-project

Prepare for notebook development in Watson Studio

This is a one-time setup of your "development" environment. (Most notebooks will use a proprietary Watson Studio package to load and store data files. Therefore notebook development should not be performed in a local Jupyter environment.)

Prepare the data set files

1. Download the compressed data set archive (.tar.gz) from Cloud Object Storage into a temporary directory.
2. Extract the archive.
3. If the data files are not of type .csv DO NOT PROCEED.

Prepare the Watson Studio development project

1. Log in to Watson Studio and create an empty project.
   • Choose meaningful name
   • Add a short project description.
   • Uncheck Restrict who can be a collaborator
2. Add a project token.
   • Click Settings.
   • Add an Access token (any name, role must be Editor).
3. Add the extracted (raw) data set files.
   • Click Assets.
   • Click Add to project > Data and add each raw data set file (e.g. .csv) to the project.
4. Try to export the data assets. If an error is raised because the archive is larger than 500MB, use the Part 0 - Import Data.ipynb notebook. Customize the notebook as follows:
   • Change the dataset_download_url
   • Change the data_path_name.
   • In the last code cell, customize the if file.suffix != '.tgz': filter as needed if the extracted archive contains files that should not be added as data assets.

Notebook development instructions

Review the notebook development instructions in /notebooks.

1. Add new notebooks ("from file") to the project using the template-notebook.ipynb in /notebooks.
2. Before saving the notebook in GHE make sure to complete the following steps in Watso Studio:
   • remove the first cell, which should look as follows

     # @hidden_cell
     # The project token is an authorization token that is used to access project resources like data sources, connections, and used by platform APIs.
     from project_lib import Project
     project = Project(project_id='4...', project_access_token='p...')
     pc = project.project_context
     

   This cell is automatically inserted when a user imports the project from the Watson Studio gallery. The project id and token are different for every user and every project instance and the content that works for you will not work for another user.

   • clear all output cells

Review notebooks using ReviewNB tool

We use ReviewNB to better visualize updates to notebooks in Github. Due to several restrictions with using this tool, this is the process for getting notebook's ready to review:

1. Create a new repository in github.com/codait if you are migrating the project from Github Enterprise.
   • Make the repository private.
   • Copy in all of the files created thus far in the project's Github Enterprise repository (we are only able to use the public Github version of ReviewNB at this time, hence the need for this step).
2. Add a branch called production to the new repository.
   • In the repository's Settings/Branches page, make the production branch the default (base) branch (Watson Studio currently can only push commits directly to the master branch of a repository, hence the need for this step).
3. Make sure you are assigned the Admin role in the Watson Studio project that you will push code to Github from:
   • If you are not assigned this role yet, you can have a current Admin grant you this privilege.
4. If your Watson Studio account does not yet have Github integration setup with your public Github account:
   • Add a Github personal access token in Watson Studio's Settings/Integration page.
   • You can create this token by visiting your public Github's Settings/Developer settings/Personal access tokens page and clicking Generate new token. Make sure to give the token repo scope.
5. Inside of the Watson Studio project's Settings page:
   • Scroll to the Integrations/Github repository section and add the link to the new Github repository you created to which you will push your code.
6. Now you are able to push commits to the master branch of the new repository you created.
   • To push a commit, open a notebook in edit mode, click the Github integration button in the top menu bar, click Publish on Github.
   • In the dialogue box, ensure the target path points to ./notebooks/your_target_notebook.ipynb, add a commit message, select All content except hidden code cells, and click Publish.
   • Follow this set of steps every time you need to make a commit.
7. Once you are ready for your notebook to be reviewed:
   • Open a PR from the master branch against the production branch.
   • Within this PR, ReviewNB will automatically add a button to Check out this pull request on ReviewNB.
   • Make sure ReviewNB is an Authorized Github App in your Github account's Settings/Applications/Authorized Github Apps page to be able to use the tool to add comments and code suggestions to individual cells of a notebook.

Source control instructions

Use this github repository to store all the artifacts that will be used to create the Watson Studio project for this data set.

• Copy the raw data set files into /data_assets following the instructions in /data_assets.
• Copy the downloaded notebook files into /notebooks following the instructions in /notebooks.
• Customize the metadata files in /metadata following the instructions in /metadata.
• Complete the legal documents in /legal following the instructions in /legal.

Packaging instructions

1. Follow the packaging instructions in dist.

Publication instructions

1. Make sure you have completed the packaging instructions.

2. Complete the notebook publication checklist for each notebook.

   • In the checklist document add a (company-wide readable) link to the completed data set publication approval request form.
   • In the checklist document add a (company-wide readable) link to the data set publication approval.
   • Save a copy of each completed document in the legal directory.

3. Send an email to @gdq:

   • subject: Publication approval request for DAX/[insert-dataset-name] notebooks
   • recipient: [email protected]
   • cc: [email protected]
   • body:
     • Requesting your approval to publish and license the following notebooks, including its source code under the terms of the MIT license.
     • for each notebook
       • include a link to the corresponding file in the source GH repository
       • attach the completed publication checklist
     • include a link to the data set's legal approval request form
     • include a link to the data set's legal approval document

4. Once the request was approved the content team will work with the legal team to require clearance for the notebooks.
