Natural Log (ln for short) is a time series database with a REST API. The database records time-varying scalars, arrays, and generic binary data at irregularly-spaced intervals, and supports time-oriented queries on that data. It is primarily intended for logging numeric data, rather than string messages like syslog.

WARNING: Natural Log is currently practicing "Documentation Driven Development," so none of the code exists to do any of this yet.

Natural Log requires:

• Python 2.6, 2.7, 3.3 or PyPy 2.1
• flask
• requests
• dateutil
• argparse (only on Python 2.6)
• numpy (or numpypy in the case of PyPy 2.1)
