TAME is The Algebraic Metalanguage, a programming language and system of tools designed to aid in the development, understanding, and maintenance of systems performing numerous calculations on a complex graph of dependencies, conditions, and a large number of inputs.
This system was developed at Ryan Specialty Group (formerly LoVullo Associates) to handle the complexity of comparative insurance rating systems. It is a domain-specific language (DSL) that itself encourages, through the use of templates, the creation of sub-DSLs. TAME itself is at heart a calculator—processing only numerical input and output—driven by quantifiers as predicates. Calculations and quantifiers are written declaratively without concern for order of execution.
The system has powerful dependency resolution and data flow capabilities.
The current state of the project as used in production is found in
src/current/. The environment surrounding the development of this
project resulted in a bit of a mess, which is being refactored into
src/ as it is touched. Documentation is virtually non-existent.
Compiled documentation for the latest release is available via our GitLab mirror, which uses the same build pipeline as we do on our internal GitLab instance. Available formats are:
To get started, make sure Saxon version 9 or later is available and its path
SAXON_CP; that the path to hoxsl is set via
HOXSL; and then run
$ export SAXON_CP=/path/to/saxon9he.jar $ export HOXSL=/path/to/hoxsl/root $ ./boostrap
Running Test Cases
To run the test cases, invoke
make check (or its alias,
Testing Core Features
In order to run tests located at
core/test/core/**, a supporting environment
is required. (e.g. mega rater). Inside a supporting rater, either check out a
submodule containing the core tests, or temporarily add them into the
Build the core test suite summary page using:
$ make rater/core/test/core/suite.html
Visit the summary page in a web browser and click the Calculate Premium button. If all test cases pass, it will yield a value of $1.
