High Water Mark discussion

This is pretty much a discussion topic about what defines a 'High Water Mark.' Are we talking 'Classic Literature?' Modern? Sci-Fi? Comicbooks(a very respected form of literature though not all see it as such) Exactly what?
I tend to be inclusionary--I think every genre has a 'High Water Mark' and I would love to see a discussion about the many and varied...

hi im kathy from ashebore nc ,, used to live in randleman years ago ,, hope you dont mind my interest in your discussion,

Hi, I'm using a nom de plume because I'm a little sensitive about criticism and I do read lots of different kinds of books and have firm opions on political issues as well. If you really want to know who I am, send me and email at luckngrace@yahoo.com and I will tell you. I do live right on the edge of Randleman and Asheboro. If you're interested in friending me on Goodreads, I will be delighted to have local friends. Then we can complare ratings and see how we mesh.

Kathy, I just looked at your page and noticed you like Stephanie Meyer. I'm not into vampire but I did read her THE HOST and loved it. I didn't think I would like it, but it kept me thinking about the book days after I read it and that is my definition of a great book. Sent you a friend invite. Hope you don't mind.

grace nice to meet ya , and yea i loved the twilight saga , books and the host ,, but that was just the start , i found so many more vamp love story books i like ,

define high water mark like this ?High-water mark was introduced in Clark Weissmann's Security controls in the ADEPT-50 timesharing system published in the AFIPS Conference Proceedings, volume 35, pages 119—133. FJCC, 1969. It pre-dates the Bell-La Padula security model, whose first volume appeared in 1972.

Under high-water mark, any object less than the user's security level can be opened, but the object is relabeled to reflect the highest security level currently open. Hence the name.

The practical effect of the high-water mark was a gradual movement of all objects towards the highest security level in the system. If user A is writing a CONFIDENTIAL document, and checks the unclassified dictionary, the dictionary becomes CONFIDENTIAL. Then, when user B is writing a SECRET report and checks the spelling of a word, the dictionary becomes SECRET. Finally, if user C is assigned to assemble the daily intelligence briefing at the TOP SECRET level, reference to the dictionary makes the dictionary TOP SECRET, too.
