Just a couple of quick notes:
As I have found processing the text of Bible versions, versification is no simple task. What happens when you have verses labeled "3/4" or "5c" or simply null, as a inter-verse portion of a chapter (all these examples from Rahfl's Septuagint). BibleOrgSysis Rob Hunt's "attempt to develop a system that is multilingual, multinational, and multicultural from the beginning—to pull all of these various Bible organisational systems into one place." The project was first announced in 2011, but it is still actively being worked on now. From the looks of the code, he's adding extensions for Drupal and other systems. Great news.
In another corner of the web, Stephan Kreutzer of Freie Bibel explains the importance of free software and free culture licensing for Bible texts. Stephan is working on contributing to the ecosystem of free software tools which can be used to proofread and edit digitized texts.
