----------------------------Original message---------------------------- I'm working on a theme keyword thesaurus to comply with FGDC Content Standard (6/8/94) Section 1.6.1. It's to be available online (intra- and eventually internet) for use by both indexers and data searchers. Can any of you point me toward examples of such a thing either online or elsewhere? I've seen what NOAA and USGS have on their Web sites and also AEGIS' Klamath software. If anyone has worked on a project like this, I'd be grateful for any suggestions or caveats. And - Does "stratum" (FGDC Content Standards 1.6.3ff) refer to what I think of as map layers, or did I just not get it? Thanks, Pat Fell
