Spotlight searching RDF metadata inside SVG format

Question

I have been using Inkscape in place of Freehand (yea I still use Freehand) and am inspired by the idea of open source, they use the SVG (Scalable Vector Graphic) format of which metadata can be stored within. However Spotlight cannot search the embedded RDF data within SVG and I would like to know if that is the end of the story??

As long as you have a single line comment, the grep/sed (or Perl) regular expression combination will find the Comment: key/value pair, and isolate just the comment text. It will not matter where in the metadata that the comment occurs.
I could have sworn late last night that the grep/sed solution was returning a left-justified comment string. This morning it is not stripping the whitespace before the comment text. The following refinement returns only the comment value without preceding whitespace.
cat test2.md | egrep 'Comment:[ \t]*(.*?)' | sed -e 's/Comment:[ \t]*//'
In AppleScript, you can assign your do shell script result (comment) directly to the clipboard without needing pbcopy. The following is a simple test that demonstrates this ability. In AppleScript, you will need to escape the tab (\t) character with an additional backslash.
set extRe to "echo 'Comment:   This is a comment.' | egrep '^Comment:[ \\t]*(.*?)' | sed -e 's/Comment:[ \\t]*//'"
set the clipboard to (do shell script extRe)
set somevar to (the clipboard)
display dialog somevar as text -- could have replaced somevar with (the clipboard)
