docassemble is a platform for creating mobile-friendly web applications called Interviews that ask one question at a time in order to reach an end point. This end point may be the presentation of legal advice, the creation of a signed legal document, the submission of an application, or something else. Run the Demonstration to get an idea for what docassemble applications look like.
For a quick introduction to docassemble authoring, look at the Hello World tutorial.
Authors write interviews in YAML format, a plain-text format that is human-readable but also machine-readable.
An interview consists of multiple “blocks.” Blocks are pieces of text
---, which is a record separator in YAML.
Some blocks are Initial Blocks, which set things up in the background.
Other blocks are Question Blocks that represent screens that the user will actually see. The basic structure of question blocks is simple, but there are a lot of possible Question Modifiers that can make your screens do different things.
The information gathered from users is stored in Python “variables,” and the purpose of most question blocks will be Setting Variables. You can use whatever variable names you want, as long as they do not conflict with any Reserved Names.
If you want, you can even use “fuzzy logic” with docassemble’s Machine Learning feature.
docassemble decides which questions to ask, and the order in which to ask them, according to the Interview Logic. You can specify the order of questions with great specificity if you want, or you can just specify an end goal and let docassemble figure everything out on its own.
A popular use of interviews is the assembly of Documents (hence the name docassemble). You write documents the same way you write questions, in plain text with Markup to indicate formatting. You can re-use text in different contexts using Templates.
When collecting information from users, it is useful to store the information in a structured way using Objects. When you want to collect one or more pieces of related information, you can structure information into Groups.
As your interviews become more sophisticated, you will find it useful to use Functions to do things like conjugate verbs, compute differences between dates, or offer the user hyperlinks that perform special actions.
docassemble is a multi-purpose platform, but it is particularly designed for Legal Applications, and has special functionality for that specific purpose.
One of docassemble’s most powerful features is its ability to operate multi-user interviews through the Roles feature.
A number of advanced features can be accessed controlled through Special Variables, such as pre-populating variables in your interview by embedding the values in the URL with which the user accesses the interview.
Interviews do not have to be ephemeral. There is a User Login system that allows users to create accounts, save their answers, and resume their interviews at a later date.
Using the Background Tasks features, you can have your interviews do things on the server at times other than times when the user presses a button to advance to a new page. Time-intensive tasks can run in the background; the interview can evaluate user input before the user submits it; and interviews can do things when the user is not logged in, like send a reminder e-mail to a user about a deadline as the date approaches.
If you need to make an interview available in more than one language, docassemble’s Language Support features can help you manage translations.
Authors will invariably make mistakes and encounter Errors. docassemble tries to provide helpful error messages in the browser or in logs stored on the server.
docassemble’s authoring system was built on the model of the open-source software development community. Interviews can be bundled into Packages, which can be shared on GitHub or moved between servers as ZIP files.
Authors can prototype and test their interviews in the browser, using the “interview developers’ Playground.”
The mobile-friendly web interface is the primary way that users will run interviews, but there is also the option of making interviews available via Text Messaging.
When you deploy your interviews, there are a variety of ways you can provide support to your users. The Live Help features allow operators to communicate with users using on-line chat. Operators can see users’ screens and even take control if necessary. If communication by phone is necessary, operators can provide users with a special phone number and code that forwards a call without revealing the operator’s actual phone number.
Authors should focus on the creative aspects of interview writing and not have to worry about how the docassemble software is made available to users on the internet.
System administrators will be pleased to know that docassemble has excellent Scalability when deployed in the cloud.
Lawyers will be pleased to know that docassemble has a number of Security features, such as server-side encryption.
Financial officers will be pleased to know that docassemble is free software available with a highly permissive open-source License.
