	2.1 Data Format
	
		The data given in this treebank is provided as an XML document.  Each 
		word contains six required attributes:
		
		id: This is a unique identifier, and corresponds to the word's linear 
		position in the sentence.  The first word in a sentence is given 
		id 1.
		
		cid: This is a canical identifier for the word within the larger corpus.
		
		form: The token form of the word, in Beta Code.
		
		lemma: The base lemma from which the word is derived, in Beta Code.
		
		head: The id of the word's parent.  If a word depends on the sentence 
		root, its head is 0.
		
		relation: The syntactic relation between the word and its parent.  A 
		catalogue of syntactic tags can be found in the syntactic guidelines 
		described below.
		
		postag: The morphological analysis for the word.  This field is 9 
		characters long, and corresponds to the following morphological 
		features:
		
			1: 	part of speech
			
				n	noun
				v	verb
				t	participle
				a	adjective

	2.4 Authorship

		Aside from the scholarly treebanks of Aeschylus (ed., Francesco Mambrini),
                Plato (ed., Giuseppe G.A. Celano) and Sophocles (ed., Dan Libatique), 
                each sentence in the Ancient Greek Dependency Treebank is built from the 
                efforts of two independent annotators (marked "primary" in the data) reconciled 
                by a third (marked "secondary").  We would like to recognize the contribution 
                of the following individuals toward its creation and thank them for their 
                commitment to the advancement of Classical scholarship:
