XFML

eXchangable Faceted Metadata Language (XFML) is a markup language which "leans very heavily on some of the concepts of topicmaps". Peter Van Dijck, its author, is "hoping it will be simple yet powerful enough to be adopted within a year by weblog software and CMS's [and that] it will make people familiar with some of the concepts behind topicmaps so that technology becomes more widely understood."
