I've been working on a Bible project of my own, trying to get the necessary permissions to use Catholic Biblical texts (which are often covered by copyright by Episcopal conferences or Biblical foundations). The project is
https://www.bibleget.io and I obtained the rights of usage for the NABRE edition so a Catholic version in English is available. I'm hoping to add more versions of the Bible over time. And I am interested in implementing Elastic Search.
I am looking forward to collaborations, to make the project more useful. I've also already started looking into CCC and other texts that are structured (such as the Divine Comedy). I have a working copy of the Divine Comedy, but I haven't made it public yet because I wanted to first get the word out about the Bible project, without creating confusion about the purpose of the project.
I have made a WordPress plugin, an OpenOffice plugin, a LibreOffice plugin. I made a MSOffice Word plugin but it doesn't always seem to work for everyone, and Microsoft makes it incredibly hard to debug this kind of plugin from Visual Studio, so I'm not sure where to start to make sure it works in all scenarios. I'm looking forward to making a plugin that will work with Office 365, if I ever get around to it. I have also made a plugin for Google Docs, which I now am updating and need to republish because Google changed the way that plugins for Docs are published.
In any case I would be very open to collaboration for this project!
