Fifty-two projects are catalogued here. The information presented in these entries is a distillation of much more detailed notes. We have attempted to present a short description that explains what the software is and does, followed by basic information about who is behind the project, in terms of leadership, development, funding, and partnership, and some basic info about its lifespan so far.
Following the *Basic Info* section is data pulled from Github and Gitlab repositories. This information is included for illustrative purposes; it is not useful for comparison, for two simple reasons: first, that the projects catalogued here are small enough that quantitative data does not tell an accurate or even compelling story; second, that governance and project management practices of these projects varies widely. As a result, metrics from Github vary much more as a result of how the developers organize themselves than due to actual activity in any given repository. Complicating further is the fact that some projects are in a single repository, and some are spread across many. We have endeavored to provide usable and credible information here, as evidence of the active status of these projects.
We have listed funding sources for each project as claimed by the projects themselves---either on their websites or in personal communication. Some projects have had many funding sources (not all are current); some project have no funding sources at all beyond the energy and time of their developers.
