Z:gnu-www-ja-categories--ca0d1a-Sometimes people use the term/en

Sometimes people use the term &ldquo;public domain&rdquo; in a loose fashion to mean &ldquo;free&rdquo; or &ldquo;available gratis.&rdquo; However, &ldquo;public domain&rdquo; is a legal term and means, precisely, &ldquo;not copyrighted&rdquo;. For clarity, we recommend using &ldquo;public domain&rdquo; for that meaning only, and using other terms to convey the other meanings.
