Converting SFM Bibles to OSIS

Introduction

Standard Format Markers (SFM) and its more standardized derivative USFM have been used for decades to store Bibles for printing and display in programs like UBS' Paratext. The format is popular among Bible translation agencies and Bible societies. The basic format of SFM is simply plaintext with backslash(\) codes. For example, a new Bible verse is signaled by \v followed by the number of the verse.

Older texts in various dialects of SFM can still be found. It was common for various agencies, Bible societies, and even regional offices of such groups to have their own SFM standards. Unified Standard Format Markers (USFM) was developed to standardize SFM and encourage interoperability so that Bibles from one agency could be reasonably expected to operate with the software and stylesheets employed by another. The current version of USFM is 2.1, defined at http://confluence.ubs-icap.org/display/USFM/Home.

Preparing (U)SFM files for conversion

The simplicity of writing SFM also makes it easy to write poor SFM that fails to correspond to any kind of standard. The first task in preparing to convert SFM files to OSIS is to clean the text.
