Usage Advice
Use when
- Use for a human-readable size or duration of a creative work — '635 pages', '47 minutes', '2.3 MB' — captured as a literal.
Avoid when
- Avoid it for pixel dimensions of an image/video (use
gmeow:pixelWidth/gmeow:pixelHeight) and for the MIME type (usegmeow:mediaType); prefer a typed quantity when arithmetic is needed.
How to use
- Carry the extent string on
gmeow:extent; for measurable image/media dimensions use the typed pixel/orientation properties instead.
Examples
- ex:book
gmeow:extent"635 pages".
