XML and SGML have revolutionized the representation of structured information, but not all information structures map easily into systems of hierarchically nested elements. Markup of overlapping structures is a perennially hot topic, reinvented and reimagined as often as it is solved.
This full-day workshop brought together the proponents of some of the major proposals for markup, representation, extraction, display, and validation of semantic overlap to summarize the systems they are developing and discuss topics of common interest. A morning of formal presentations was followed by an afternoon of free-ranging discussion.
Keywords: Concurrent Markup/Overlap
