Event Sequence Analysis Library

Esal ("easel") is a library for representing and querying event sequences and timelines.

Features

This project is in the early design and implementation stages. The implemented features are:

• Event objects
• Event sequence data structure for the efficient querying of event sequences
• Interval objects
• Allen's interval algebra (constant-time implementation that uses only a few comparisons)

Other features have already been implemented but haven't yet been organized into an official API. Feel free to look through the code. Suggestions are welcome.

Requirements

• Python 3

Install

pip3 install [--user] https://github.com/afbarnard/esal/archive/<name>.zip#egg=esal
