This introduces a number of abstractions, whose concepts are not fully documented yet since I want to see how it evolves in practice first. This introduces the concept of edge ontology (similar to a schema) using the type system. Even though we are not able to determine what the graph will look like statically---since that's determined by data fed to us at runtime---we _can_ ensure that the code _producing_ the graph from those data will produce a graph that adheres to its ontology. Because of the typed `ObjectIndex`, we're also able to implement operations that are specific to the type of object that we're operating on. Though, since the type is not (yet?) stored on the edge itself, it is possible to walk the graph without looking at node weights (the `ObjectContainer`) and therefore avoid panics for invalid type assumptions, which is bad, but I don't think that'll happen in practice, since we'll want to be resolving nodes at some point. But I'll addres that more in the future. Another thing to note is that walking edges is only done in tests right now, and so there's no filtering or anything; once there are nodes (if there are nodes) that allow for different outgoing edge types, we'll almost certainly want filtering as well, rather than panicing. We'll also want to be able to query for any object type, but filter only to what's permitted by the ontology. DEV-13160 |

TAME
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.
TAME consists of a macro processor (implementing a metalanguage), numerous compilers for various targets (JavaScript, HTML documentation and debugging environment, LaTeX, and others), linkers, and supporting tools. The input grammar is XML, and the majority of the project (including the macro processor, compilers, and linkers) is written in a combination of XSLT and Rust.
TAMER
Due to performance requirements, this project is currently being reimplemented in Rust. That project can be found in the tamer/ directory.
Documentation
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:
Getting Started
To get started, make sure Saxon version 9 or later is available and its path
set as SAXON_CP
; that the path to hoxsl is set via HOXSL
; and then run
the bootstrap
script:
$ 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, make test
).
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
submodule.
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.
Hacking
Information for TAME developers can be found in the file HACKING
