Our first full week hackathon starts Saturday 9/1, building an MVP version for testing by nonprofits and neighborhood organizations. There will be events in Los Angeles on Saturday 9/1 @ 10AM and Tuesday 9/4 @ 6PM. Join us anytime online at slack.ctree.org to participate.
The Collaboration Tree (cTree) is a new web technology aimed at facilitating more productive discussions around a specific topic, usually a goal or problem to solve. Initially the goal is to help nonprofits communicate more effectively with their communities, but the potential uses stretch far beyond that. Other community based web technologies like forums and wikis can be used at small scales, but are less useful for larger topics or groups. Collaboration Trees will allow the quick interactions most users are accustomed to, while maximizing the usefulness of their interaction and organizing the larger discussion.
With Collaboration Trees, all points are tied together, and by default can all be traced back to a core point, like a specific topic or problem to solve. Each point can be updated and improved by the community, similar to a wiki, but unlike most wikis, the highest rated version wins and is shown by default. Alternate versions are easily available and can be individually discussed and rated. The type of data in each point is pluggable, with initial defaults of text and images. Feedback with supporting content like quotes or links to supporting information are ranked higher by default.
Eventually the project will leverage AI to intelligently suggest things for users to interact with that interest them, match their stated and observed strengths, and can have a meaningful impact on the discussion. For example, users who often provide useful feedback on new ideas may be more likely to see a new idea nobody has given feedback on. Another example would be if a user tends to rate things in a way that matches most other users or users of a specific group, their ratings would be more valuable and they'd be more likely to see something which hasn't been rated before it's potentially shown to other users.
While the project is open source and can be integrated into any website, the goal is to also create a hub site where all public cTrees can be found. This will help with discovery as well as evangelize the use of the technology both on the hub site and on unaffiliated sites. At its peak, the largest cTrees will likely develop their own sub-communities with their own input plugin sets.
This specific project is intended to show how the Collaboration Tree hub site will work. The goal is to have a functional front-end demo where users can put in real data and give feedback on what works and what doesn't about the structure. Broad browser support, the intelligent suggestion backend, and some other low priority features are out of scope for this demo. Even though this is a demo, the components developed for it will be the foundation for the full hub site and should be clean and complete enough to use in production.
Technology (Polymer Web Components & beyond)
This project is based on Google's Polymer Project, which is a collection of highly polished web components. We chose web components because we want people to be able to easily integrate cTree elements into existing sites, and Polymer does a lot of the heavy lifting for creating a modern responsive site. Web components have also grown to be a true web standard, with broad native browser support.
One aspiration of this project is to follow the "PRPL pattern". This pattern allows fast first delivery and interaction with the content at the initial route requested by the user, along with fast subsequent navigation by pre-caching the remaining components required by the app and progressively loading them on-demand as the user navigates through the app.
The PRPL pattern, in a nutshell:
- Push components required for the initial route
- Render initial route ASAP
- Pre-cache components for remaining routes
- Lazy-load and progressively upgrade next routes on-demand

We've set up a page to showcase the latest code for the demo site at http://demo.ctree.org. This is just for development testing purposes and may not always include the latest code. If you want to see the latest code in action, your best bet is to clone this project and run it on your local machine. Keep in mind that it's a work in progress, with lots of randomly generated data and bugs on some platforms. Try not to be thrown off by the random data, and instead focus on the features and structure of the web app.
Verified Configurations Working
The preferred method of communication for the community is our Slack group. There are also regular events held in Los Angeles, CA and online to encourage contributors to set aside time to work on the project. If you're interested in starting events in your area please email contact@innovativeFuture.org. There are also Facebbok and Twitter sites where you can keep up with the project, as well as a LinkedIn organization you can list on your profile if you're a regular contributor.
Because of the size of the project, issues are broken down into teams. Contributors looking to bolster their resume may find it more useful to pick a team to work with so they can point to that specific work rather than specific changes or the project as a whole, though there's no requirement to work on issues for a single team. The current teams are:
This team is responsible for implementing the new landing page shown to users when first opening the site. It's a way to introduce the technology to people who aren't familiar with it and help them get started with the site. This is a high priority part of the project, required before we can start alpha testing.
This team is responsible for implementing the database to hold and access all user and collaboration tree data. For the alpha version this means duplicating the randomly generated data structures and interfaces and backing them with a real online database, likely Firebase due to native Polymer support. This is a high priority part of the project, required before we can start alpha testing.
One of the core ideas behind Collaboration Trees is that contributors can quickly contribute by skimming suggested elements. This makes reviewing the most popular elements and overall structure of the tree more difficult for anyone trying to watch the progress of the tree or check for an answer if a question or problem was used as the seed for the tree. This team is responsible for creating and integrating different visualizations of the overall data. This will aid alpha testing, but is not yet a requirement before it begins.
Elements are the individual pieces which make up all Collaboration Trees, similar to comments in a forum or pages on a wiki. Because of this, elements require more work, which has been divided into sub-teams.
This team is responsible for implementing everything required to create new elements, whether they're the first element for a new Collaboration Tree, a new element related to another element, or a new element which needs to be linked to another element. This also includes the important task of looking for other existing elements which may be similar and suggesting them to the user to try and reduce duplicates. Because this is required for building cTrees, the core functionality is required before we can start alpha testing.
This team is responsible for the core details screen of the element dialog. The core functionality is already implemented, but can be improved to be more intuitive. This team is also responsible for adding additional types of input for elements via the pluggable structure.
Feedback is a core component for Collaboration Trees, being supported for each element variation as well as each variation of each piece of an element. This team is responsible for making the element dialog's feedback screen fully functional, including listing, sorting, and adding feedback. One unique feature of cTree comments is that supporting data, like images, quotes, or studies, is encouraged by increasing their visibility when included. This team is also responsible for the up/down vote functionality supported both on the feedback screen and details screen of the element dialog.
Elements list a summary of top contributors on their preview and details screen, which takes the user to a summary of all contributors and their contributions to the element. This team is responsible for both the summary and page listing all contributors.
This team is responsible for the dialog listing information for and about users. The dialog will contain information to allow users to review a summary of their contributions as well as update their public and private account information. This team will not be responsible for implementing the temporary accounts used for alpha testing, but may build on it to implement the dialog.

Start the development server
This command serves the app at
http://localhost:8081 and provides basic URL
routing for the app:
This command performs HTML, CSS, and JS minification on the application
dependencies, and generates a service-worker.js file with code to pre-cache the
dependencies based on the entrypoint and fragments specified in
The minified files are output to the
build/unbundled folder, and are suitable
for serving from a HTTP/2+Push compatible server.
In addition the command also creates a fallback
generated using fragment bundling, suitable for serving from non
H2/push-compatible servers or to clients that do not support H2/Push.
Test the build
This command serves the minified version of the app in an unbundled state, as it would be served by a push-compatible server:
polymer serve build/unbundled
This command serves the minified version of the app generated using fragment bundling:
polymer serve build/bundled
We can extend the app by adding more elements that will be demand-loaded
e.g. based on the route, or to progressively render non-critical sections
of the application. Each new demand-loaded fragment should be added to the
fragments in the included
polymer.json file. This will ensure
those components and their dependencies are added to the list of pre-cached
components (and will have bundles created in the fallback
