next generation of Sky in Google Earth

At the last NVO (or VAO) telecon I was on we discussed the meta-tags
again especially those now put forward by
the VAMP group. The Office of Public Outreach and I have been working
with the VAMP group for years, and as you
all know the meta-tag project for data, multimedia, and educational
resources originated and was implemented
in the 1990s with the NASA Space Science infrastructure.
I would like to see the meta-tag issue get more VAO attention and be
embraced by the VAO and the larger IVOA community.
We folks involved in education continue to move ahead on this.
The ability to put the meta-tags in KML (which is possible) and to
use them effectively (which has yet to be seen)
will certainly help public access, and I am sure, help with the
"keyword searching" interfaces and standards
that the NVO team is working on.
