Open Scripture Information Standard ( OSIS ) is an XML application (or schema ), which defines tags for marking up Bibles, theological commentaries, and other related literature.
The OSIS was developed by the Bible Technologies Group, a joint committee sponsored by the American Bible Society and the Society of Biblical Literature . Other participants in the standards are the United Bible Societies , SIL International , and various national Bible societies, along with individual expert volunteers. The officers include Steven DeRose (chair), Kees DeBlois (vice chair), and Patrick Durusau (editor). As of mid-2006, the current version is 2.1.1.
The scheme is very similar to That of the Text Encoding Initiative , though on the one hand much simpler (by omission of Many unneeded constructs), and on the other hand Adding much more detailed metadata , and a formal canonical reference system to Identify books, chapters, verses, and particular locations within verses.
The metadata includes a “work declaration” for the work itself, and for each work it references. A standard core , and assigns a local short name for the work (similar to XML namespace declarations).
OSIS gives particular attention to the encoding of overlapping markup , because Bibles exhibit such markup frequently, for example verses crossing paragraph boundaries and vice versa. The OSIS schema introduced a method for encoding overlap in XML, known as Trojan milestones , or “Clix”.
