Metadata - Attributions and FGDC Metadata
Each layer served by the SVS Image Server contains an <Attribution>
element which provides a credit line and directs the user to the entity responsible
for creating the animation. For the specific case of animations created by the
Scientific Visualization Studio, this element
has the following form:
<Attribution>
<Title>National Aeronautics and Space Administration</Title>
<OnlineResource xmlns:xlink="http://www.w3.org/1999/xlink"
xlink:type="simple"
xlink:href="http://svs.gsfc.nasa.gov/vis/a000000/a002800/a002890/"/>
<LogoURL width="312" height="258">
<Format>image/png</Format>
<OnlineResource xmlns:xlink="http://www.w3.org/1999/xlink"
xlink:type="simple"
xlink:href="http://svs.gsfc.nasa.gov/svs_icons/nasalogo.png"/>
</LogoURL>
</Attribution>
These animations are attributed to NASA, with a link to the NASA logo,
and the <OnlineResource> points specifically to the SVS
page that describes the animation and provides other downloadable
resources for the animation, such as movie files and still images. This page is considered
the authoritative resource for information about the animation.
Within each layer description, there is also an entry directing the user to a formal
metadata description for the animation that that layer represents, which looks like this
for the African Fires layer:
<MetadataURL type="FGDC:1998">
<Format>text/plain</Format>
<OnlineResource xmlns:xlink="http://www.w3.org/1999/xlink"
xlink:type="simple" xlink:href="http://svs.gsfc.nasa.gov/vis
/a000000/a002800/a002900/a002890.fgdc"/>
</MetadataURL>
In this instance, FGDC:1998 identifies the metadata file as
adhering to the Content Standard for Digital Geospatial Metadata, as
published by the Federal Geographic Data Committee (see the
standards page). The URL
within the <OnlineResource> element points to the metadata file
itself, which starts like this:

Description
Abstract: ...
Currently, the FGDC Metadata file contains little information that is not
already in the Capabilities XML document. In the future, it is envisioned that
the metadata file will contain more detailed information about the
animation, the data it represents, and the science behind it.
