YAXDF

yaxdf (Yet Another Extended Data Framework) is many things. It is a simple tag-based, table-oriented, data format related to STAR and CIF. It is a complex tree-oriented markup languages related to XML. It is a structure within which to convey MIME data. It is a static. It is dynamic and object oriented. It is well-defined and it is evolving. It is what its users make of it... The relationship of yaxdf to other data frameworks is similar to that of English to other natural languages. English is an agglomeration of multiple languages, which has enough common structure to allow those who speak it to communicate, but which has enough of "give" to absorb any useful new words and modes of expression that people may find useful.
