Definition: The word 'glyph' does not mean 'neume': glyphs just are components of graphical presentation. A glyph can correspond to a neume, part of a neume, or a non-neumatic symbol. In naming our glyphs, we have 'borrowed' from the names of neumes, but a crucial distinction must be made between concrete visualization and abstract representation: for purposes of the NEUMES Project, glyphs are 'concrete', and neumes are 'abstract'. [See the 'Data Representation' section of this website for our taxonomy of neumes as logical entities in transcriptions.]

Technical remarks: This visualization of glyph image sets is "data-driven" and dynamically generated. For each glyph image set, the 'raw data' are contained in an XML file, as regulated by an XML Schema. A single XSL (Extensible Stylesheet Language) Transformation generates the HTML visualization for all Glyphs Manifest XML files. This is done anew each time the user clicks on one of the hyperlinks (above), so that the user is seeing necessarily the most current data. Dynamic-generation permits also that developers of glyph image sets can see visualizations of Glyphs Manifest data they are creating offline. This "data-driven" strategy of software design largely precludes one layer of software maintenance; viz., separate HTML pages for the glyph image sets do not have to be written and kept current.
