Overview

What's the problem?

Concerned and impacted citizens don't have a straightforward way of knowing what or how policies, regulations, and legislation (throughout this document referred as either Legislative Artifacts or PR&L) impact them or how they can share their approval, concerns, and/or questions with lawmakers.

How can technology help?

What is missing to help communities contribute their feedback related to PR&L, and what this technology was intending to provide, is a means for people to:

• readily understand the PR&L language and intent without being a legal expert
• sort or filter the PR&L efficiently
• digest an understandable summary of PR&L
• explore related or supporting information, advocacy groups, and other PR&L
• make a determination of whether the PR&L will impact them
• engage in the process of providing feedback about PR&L
• communicate the potential effects of these PR&L on their life, family, or community to the author or sponsor of the legislation
• share their stories and experiences with fellow residents and policy makers
• see what other people in the community are saying
• get an idea of the general sentiments people have expressed about the PR&L
• engender dialogue between residents, PR&L authors, and sponsors

The Idea

The driving idea behind the software is to provide a platform that is capable of storing curated PR&L information, as determined by the community (however large or small) it serves. The platform provides a mobile-friendly way for users to examine PR&L, helping increase their legal awareness and allowing them to communicate their reactions and thoughts with video testimonials. These testimonials are then shared with the community and those responsible for the creation of the PR&L.

Diagrams

This solution combines a media server (currently Watson Media) and distributed database service to hold the curated legislative artifacts and the related metadata.

• The user launches the web app (on either a laptop, desktop, or mobile device) and can view the range of curated legislative artifacts (1). The Vue app retrieves these by sending a REST request to the API server, which extracts them (3) from the SQL database.
• The user can post their own (video) story to support or challenge the legislated artifacts to the API server, which directs it to the Watson Media services (2). The API server also stores a reference to the video location in the respective legislative artifact in the SQL database (3).
• The user can view other peoples' video stories which are retrieved by sending a REST request to the API server, which, after looking up the ID of the video in the SQL database (3), extracts them from Watson Media services (2).

There is an administrative API interface that allows the site owners to curate the PR&L information, with the following attributes:

• a simple, intelligible summary that makes it easy to understand its potential impact
• categories it pertains to (law enforcement, healthcare, zoning)
• geospatial areas of pertinence (postal codes, cities, counties, and so on)
• the type of the artifact (bill, law, policy, regulation, and so on)
• related PR&L in the system
• legislator, author, and sponsor of the PR&L
• related advocacy groups or digital social communities
• related articles or supporting documentation
• a link to the full text of the PR&L

Getting started by installing and running the components

Prerequisites

• Register for an IBM Cloud account.
• Install and configure IBM Cloud CLI.
• Install Vue CLI dependencies
• Clone the repository.

Steps

1. Provision a PostgreSQL instance on the IBM Cloud.
2. If you want to use the video services, provision an instance of Watson Media.
3. Configuring and run the server.
4. Configuring and run the client application.

1: Provision a PostgreSQL instance

The server requires an RDMS server and currently only supports PostgreSQL. You can deploy this in the IBM Cloud by logging into the IBM Cloud and provisioning a Postgres instance. Note that this does require a paid plan, however if you have just signed up for a new IBM Cloud account, you will have received cloud credits, which would cover this for a significant time.

1. Choose your Databases for Postgres plan. You should choose an appropriate region, give the service a name. You can leave the other settings with their defaults. Click the blue Create button when ready.
2. Once your Postgres instance has been created, you need to create a service credential that the API Server can use to communicate with it. By selecting your running Postgres instance, you can choose Service credentials from the left menu. Create a new service credential and give it a name (it doesn't matter what you call it).
3. Once created, you can display the credentials by selecting view service credentials, and then copying the credential, so you are ready to paste parts of it into the environment file of the API server in Step 3.

Alternatively, you could deploy your own PostgreSQL instance locally, in a remote VM, or container. In this case, ensure you obtain the equivalent credentials to those described above for Step 3.

2. Set up an instance of Watson Media

Log in to IBM Cloud and provision a Watson Media instance.

1. Provision an instance of Watson Media IBM Watson Media. You can use the 30 day free-trial to start.
2. Once your Watson Media instance has launched, go to the API/SDK access item, under the Integration & Apps item, in the left menu.
3. Create a new credential. You will need to enter an Application Name (you can choose anything) and a Redirect URL. This URL needs to be the prefix of the URL you will run the server on, e.g. http://localhost. Make note of the client id and client secret, since you will need these in Step 3.
4. Generate a device username and password to be used by your server, by going to the Device passwords in the API/SDK access menu. Give your device any name you choose, and then click Create password. Make a note of the username and password that are generated, since you will need these in Step 3.

3. Configuring and running the server

To set up and launch the server application:

1. Go to the server directory of the cloned repo.

2. Copy the .env.example file, and create a new file named .env.

3. If your PostgreSQL server uses SSL (like the IBM Cloud version), then create a file to hold the SSL certificate. For the IBM Cloud version of PostgreSQL, it is shown in the certificate: certificate_base64 attribute of the service credential you obtained in Step 1. Copy the raw contents of this attribute into the file you have created.

4. Update the newly created .env file and update the DB_HOST, DB_USERNAME, DB_PASSWORD, DB_PORT and DB_DATABASE_NAME with the values from the credentials you obtained in Step 1. If you created a certificate file in the previous action, then also update the DB_CERTFILE with the location of this file (relative to the server directory).

5. Also update the CMS_USERNAME, CMS_PASSWORD, CLIENT_ID and CLIENT_SECRET with the values from creating your instance of Watson Media, from Step 2.

6. Prepare to initialize the database with the correct tables. Scripts are provided that do this using the psql cli, which is recommended that you install. On macOS, for instance, you can do this with the brew command:

   • brew install libpq
   • You may also like to link the psql command to you local bin directory with brew link --force libpq

7. To initialize the tables, you can use the ./psql_create_tables.sh script

8. If you would like to install sample data into the database for testing, then use the ./psql_refresh_sample_data.sh script

9. To run the server, from a terminal, in the server directory of the cloned repo:

   1. Install the dependencies: npm install
   2. Launch the server application locally or deploy to IBM Cloud:
      • To run locally:
        1. Start the application: npm start
        2. The server can be accessed at the address give, typically http://localhost:5000
      • To deploy to the IBM Cloud in Cloud Foundry:
        1. Edit the name value in the manifest.yml file to a unique application name (for example, my-legislative-server).
        2. Log in to your IBM Cloud account using the IBM Cloud CLI: ibmcloud login
        3. Target a Cloud Foundry org and space: ibmcloud target --cf
        4. Push the app to IBM Cloud: ibmcloud app push
        5. The server can be accessed at the routes URL displayed in the output of the push command (for example: <my-legislative-server.eu-gb.mybluemix.net>)

Once the server is running, you can test it by accessing the openAPI docs interface using the /api-docs endpoint. For example, if running locally this will be on http://localhost:5000/api-docs, which should look something like this:

4. Configuring and running the client application

To configure and run the client application:

1. Go to the client directory of the cloned repo.
2. Copy the .env.example file to a new file named .env
3. Edit the newly created .env file:
   • Update the SERVER_URL with the URL to the server app launched in the previous step (for example http://localhost:5000).
4. From a terminal:
   1. Install the dependencies:
      • npm install
      • npm run serve
   2. Once the development server is running, you should be able to access the client from the URL indicated (typically http://localhost:8080/)
   3. If you are running a mobile simulator, you can also access the same URL. For example, in the ios simulator, the screen would look something like this:

Future Enhancements to the Solution

There are a significant number of areas where the community is looking for help. Individual issues are raised in the repository, but the following class of assistance is needed:

• Media services: The current approach supports only one media service, Watson Media. Although this provides excellent capabilities, there is a desire to support a broader range of media services for testimonial videos. Various approaches have been researched, including use of a non-streaming solution using Cloud Object Storage to call stored videos to be downloaded and then played back to the user upon loading of the page. As the videos will have a restriction of 60 second time limits, optimization can be made to minimize the overhead of waiting to download the entire video before playback. This implementation is certainly feasible, however it is not scalable when taking into account users with potentially weaker network connections.
• Security: An efficient expansion to secure data storage (particularly regarding the video implementation) is required to ensure all user data is kept safe. Implementation of user accounts that safely store user data may even assist in developing a more convenient solution, however the privacy implications that come with this should also be assessed.
• Privacy considerations around videos and location information: Consideration of the metadata around user testimonials will be essential in providing a solution that focuses on privacy risks.
• Sourcing legislation information: Several data sources will be required to adapt the solution for all locales, therefore expansion of this project will be impacted massively by taking into account the structures of legislation from other countries.
• Policy upload and curation: Thought needs to be given to who would curate the policy data. Would the database population of policy data be automated to pull all newly proposed policies from government sources, requiring an interface to filter suitable policies to then be pushed into the database? Or would the curation be done manually, which allows for more control with the drawback of lower scalability?
• Moderation of uploaded videos/text: How is video or accompanying text reviewed to ensure community guidelines are being followed, and that users are not misusing the application? Applications of moderation can include profanity detection, manual moderation via user admins, or through flagging and reporting of user content. Furthermore, consideration should be made to assess whether these implementations address the spirit of the solution, e.g. how to distinguish this software from social media settings where users already share political views.
• Natural language technology: Work has already begun on refining a pipeline to extract text from video submissions to implement tone analysis, which will help to identify various characteristics and give more meaning to the video testimonials from users. Further expansion can be made to analyze profanity and inappropriate language submitted by users, to address moderation of user content.

Privacy Considerations for Implementors

Due to the nature of the solution, Personal Information (PI) could be prevalent within an implementation of a Truth Loop system. For implementors, there are a number of important considerations to take into account. Please refer to the Platform Privacy Statement and Application User Guide documents to help you with your implementation.
