Wikipedia:WikiProject Opera/FL criteria

A featured list exemplifies our very best work. In addition to meeting the requirements for all Wikipedia content—in particular, naming conventions, neutrality, no original research, verifiability, citations, reliable sources (taking particular care with living persons), non-free content and what Wikipedia is not—a featured list has the following attributes:
 * 1) Prose. It features professional standards of writing.
 * 2) Lead. It has an engaging lead section that introduces the subject, and defines the scope and inclusion criteria of the list.
 * 3) Comprehensiveness. It comprehensively covers the defined scope, providing a complete set of items where practical, or otherwise at least all of the major items; where appropriate, it has annotations that provide useful and appropriate information about entries.
 * 4) Structure. It is easy to navigate, and includes—where helpful—section headings and table sort facilities.
 * 5) Style. It complies with the Manual of Style and its supplementary pages.
 * 6) Visual appeal. It makes suitable use of text layout, formatting, tables, and colour; it has images if they are appropriate to the subject, with succinct captions or "alt" text.
 * 7) Stability. It is not the subject of ongoing edit wars and its content does not change significantly from day to day, except in response to the featured list process.
