This report presents new developments in three areas pertaining to Text As Graph (TAG), a data model that conceptualizes “what text really is” as a property hypergraph, which we first introduced at Balisage 2017. (Haentjens Dekker and Birnbaum 2017) In this new report 1) we propose a markup language for TAG, which we call TAGML; 2) we discuss a workflow, implemented in our Alexandria reference implementation of TAG, for editing TAG documents selectively, so as to retain a legible interface; and 3) we introduce some modifications in the TAG data model (principally the use of undirected edges to connect Text nodes).
