Perseids collaborative platform for annotating text re-uses of fragmentary authors

The goal of this document is to present a fragmentary texts demo built under Perseids, a collaborative platform being developed by the Perseus Project that leverages and extends pre-existing open-source tools and services to support editing and annotating TEI XML documents in Classics: http://sites.tufts.edu/perseids/ [1]. The aim of this use case is to build a shared environment for multi-level annotations of text re-uses of ancient lost works: http://perseids.org/sites/berti_demo/index.html.
