Cicero allows you to define natural language contract and clause templates that can be executed by a computer. These could be relatively simple things like if the goods are more than [{DAYS}] late, then notify the supplier of the goods, with the message [{MESSAGE}]. or more elaborate natural language and logic such as computing interest on a loan, or calculating penalties based on IoT sensor readings.

You can browse the library of Open Source Cicero contract and clause templates at: https://templates.accordproject.org.

Cicero is an Open Source implementation of the Accord Project Template Specification. It defines the structure of natural language templates, bound to a data model, that can be executed using request/response JSON messages.

You can read the latest user documentation here: http://docs.accordproject.org.

Using Cicero you can take any existing natural language text (typically a clause or a contract) and declaratively bind it to a data model. Cicero generates a parser (using the Earley parser algorithm) to parse and validate source text, extracting machine readable/computable data. The Cicero engine can then be used to execute a Smart Clause™ (an instance of a template) against a JSON payload. Smart Clause™ software can be used to add computable functionality to any document. Clauses are typically stateless (idempotent) functions. They receive an incoming request and the template data, and they produce a response.

We are an open community and welcome both lawyers and technologists to work on the specifications and code. If you would like to get involved please join the Accord #technology-wg Slack channel by signing up here: https://www.accordproject.org.
