XSIL
XSIL is an XML-based transport language for scientific data, supporting the inclusion of both in-file data and metadata. The language comes with an extensible Java Object (computer science) model. The language's elementary objects include Param (arbitrary association between a keyword and a value), Array, Table (a set of column headings followed by a set of records), and Stream, which enables one to either encapsulate data inside the XSIL file or point to an external data source.BFD is an XML dialect based on XSIL.
