The Chemical MIME Project
"Chemical MIME" is a de facto approach for adding MIME types to chemical streams.
This project started in January 1994, and was first announced during the Chemistry workshop at the First WWW International Conference, held at CERN in May 1994. The first version of an Internet draft was published during May–October 1994, and the second revised version during April–September 1995. A paper presented to the CPEP (Committee on Printed and Electronic Publications) at the IUPAC meeting in August 1996 is available for discussion.

Famous quotes containing the words chemical and/or project:
“We do not want actions, but men; not a chemical drop of water, but rain; the spirit that sheds and showers actions, countless, endless actions.”
—Ralph Waldo Emerson (1803–1882)
“In 1862 the congregation of the church forwarded the church bell to General Beauregard to be melted into cannon, “hoping that its gentle tones, that have so often called us to the House of God, may be transmuted into war’s resounding rhyme to repel the ruthless invader from the beautiful land God, in his goodness, has given us.””
—Federal Writers’ Project Of The Wor, U.S. public relief program (1935-1943)
