[0] USFX (18 March 2005 - present) [1] USFX is just an XML schema to represent USFM data in a fairly straightforward, simple manner. USFX does have a few extensions that may make it useful as a conversion hub between USFM and other standards, such as OSIS. [2] Yes [4] Easy [5] The Haiola is its main use, but there are a few others. However, by converting to USFM, you can use all existing applications that support USFM. [6] USFX started as an internal standard for the Onyx project (since renamed to WordSend and then mostly absorbed into Haiola, but it is freely available for others to use. Since it is based on USFM and easily convertible to and from USFM, its usefulness depends entirely on the acceptance of USFM. USFX changes to enable new features where it makes sense to do so, with an eye towards backward compatibility. [7] Use USFX in conjunction with USFM where it makes sense with new software tools, or as a stepping stone between USFM and whatever you want to do with XSLT and other XML software tools. [3]
