Eventually we will deploy a less monolithic document with additional features (such as sorting and filtering), correct citations, and a better layout.
Please contribute edits by forking the repository and submitting a pull request.

For every identified software package, we report its primary URL and software license and assign it an activity code. For simplicity, BSD-like licenses (e.g. NCSA) are reported as BSD. Activity codes consist of a development activity level (alphabetical) and usage activity level (numerical). Activity codes were assigned as follows:
A
Substantial development (e.g. a new major release, the addition of new features, or substantial refinements of existing features) within the last 18 months. Note this includes all projects that were created in the last 18 months.
B
Evidence of some development within the last 18 months such as a minor release or bug fixes to a development branch.
C
No evidence of development (changes to the source code or documentation) within the last 18 months. Note that in cases where a package does not follow an open development model (i.e., source is only released with official releases) the estimate of development activity will be overly conservative.
-
Substantial user usage within the last 18 months (more than 20 downloads a month on average from SourceForge, more than 20 stars or forks on GitHub, more than 10 citations a year, and/or a clearly active user community as indicated by traffic on mailing lists or discussion boards).
-
Moderate user usage within the last 18 months.
-
Minimal or no identifiable user usage within the last 18 months (fewer than 50 downloads total on SourceForge, three or fewer stars and/or forks on GitHub, or fewer than one citation a year).
We omit some packages with extended periods of inactivity (e.g. more than 10 years) where there is little evidence of any usage or packages that are referenced in the literature but for which we could not find a extant source code repository. We also omit packages that provide common and/or trivial functionality (e.g. molecular weight calculators) and those that require non-open source packages in order to function.
