XSDIF
From Libre Aquatics Wiki, the free aquatics reference
This article is a stub. XSDIF is an XML form of United States Swimming’s interchange
format, named in an LSC registration procedure as one of the three file types a club’s
software must be able to produce for the SWIMS database, carried in .xml files alongside
SDIF version 3 and Hy-Tek’s CL2.
No specification for it has been found, and USA Swimming’s own description of it is no longer reachable; see the software overview for what this section covers.
