threepress.org is a repository for open source software designed for use by publishers.
What this means is:
- All of the software is free, meaning there is no cost associated with it. It also means free in the sense of unencumbered: it can be modified or re-purposed for any use, including commercial use.
- Most packages re-use other tools (which are themselves open source, but may have slightly different licensing restrictions). One of the goals of threepress is to maximize existing toolkits — carefully modified to suit the needs of publishers — but not to re-invent whole processes.
More pragmatically, theepress also serves as a sandbox for me to experiment with projects as part of my consulting business. Although in many cases it will be impossible to do so, I hope to convince publishers that it is in their own interest to use and release projects in an open source context.
