ePSD2 generally uses the same annotation as Oracc generally.  This
is described from the perspective of people working projects on the
Oracc lemmatization page and on the
Sumerian annotation page.
To summarize, we use the following terminology and elements in annotating Sumerian:
  - CF: Citation Form
 - The headword used in the dictionary.
  In general, ePSD2 headwords use the long forms of words, and
  explicitly include the final -k in genitive compounds.
 
  - GW: Guide Word
 - A label for the word which is primarily
  intended as a way of disambiguating homophones.  Guide Words are not
  necessarily a "basic" meaning for the word. Although in practice this
  is often the case it is not a requirement.
 
  - POS: Part Of Speech
 - The reference part-of-speech for the
  word: in some cases words are used both as nouns and as verbs and it
  is not always obvious which to use as the reference
  part-of-speech in which case we simply make a conventional choice. See EPOS.
 
  - SENSE
 - Senses are indicative of the range of meanings of
  words.  An ongoing objective for future work on ePSD2 is to improve
  annotation of the corpora with regard to senses in order to provide
  a more nuanced understanding of the ways words are used in
  context.
 
  - EPOS: Effective Part of Speech
 - This is the
  part-of-speech that goes with an individual sense.
 
  - BASE
 - Rather than use the term 'root' we use the term
  'base' to indicate the portion of a word-form that writes the word
  itself rather than any attached morphological markers.  Two special
  notations are used for Sumerian bases for situations where a single
  grapheme combines morphology and base.  When the first part of the
  grapheme is morphological and the second part belongs to the base,
  we separate them with the degree symbol, °, as in 
b°e₂
  for b+e.  When the first part of the grapheme belongs to the base
  and the second is morphological, we separate them using the centred
  dot, ·, as in e₂-udu-k·a, a writing of
  eʾuduk[sheephouse]. 
  - CONT: Continuation
 - Continuation graphemes are annotated
  explicitly because they often give information about th ending of a
  word.  They have the form 
+-ga=g.a meaning that the
  base is followed by GA, writing the end of the base, g, and some
  other item, a.  There is some inconsistency in ePSD2 about when a
  CONT is used and when a centred dot is used in the base: this will
  be rectified in a forthcoming release. 
  - MORPH: Morphology
 - The morphology string follows a simple
  set of conventions for which preliminary documentation is available
  on the morphology pages.
