I would like to avoid an extra field. At least, as a database
construction. If author really wants to push certain keywords not
mentioned
anywhere in the text - he can add an annotation with such words.
Normally - it should be not necessary. I see no use in keywords not used
in the text unless these keywords are trying to describe a binary
object.
But then we better provide a text description of such object anyway.
Here is
the example:
<umo title="Great Wall of China>
<text> This is the only object build by Humanity that can be seen
from the
Moon. This is BS, BTW. I tried to look it up in Google maps and had a
hard
time finding it.
....
</text>
<attachment type="picture" file="GreatWall.jpg"
storage="We_have_to_come_up_with_something">
<annotation> The picture of The Great Wall taken in 1999 from the plane
</annotation>
<keywords> Big Grey Wall </keywords>
</attachment>
<text>... </text>
...
</umo>
While indexing this fragment, we may collect all the keywords from
<text>
tag contents. We may ignore everything from <attachment> but
<annotation>
and <keywords> contents.
Now, if the author removes a picture from this UMO, the keywords are
rebuilt, and we have no reference on that picture in the keywords
anymore
(in this version of the UMO).
