If one downloads from the SignPuddle without naming
the sign, the word "glyph" is used for the whole sign
representation.
That is incorrect. SignPuddle uses the term glyph only for
individual symbols of the ISWA.
In SignPuddle, if you save a sign that doesn't have a name
associated with it, it will use the term glyphogram: a writing of
glyphs handled as a single unit.
I use the term glyph and glyphogram as the name of 2 different
scripts in the SignWriting Image Server. The glyph script produces
symbol images. The glyphogram script produces sign, column, or row
images.
The basic writing mark of SignWriting is a symbol that is associated
with a phoneme. The basic writing mark of a logographic script is
the word which represents a morpheme. SignWriting is not
logographic.
