[Marble-devel] Regarding addition of bookmark tag

[gaurav gupta]

Hello folks,

I am planning to implement BookMark functionality in the marble. Initially
it was suggested to save it as a placemark and when visibility is false it
will work as Bookmark.

But my view about this is there is no reason to use placemark as a bookmark,
because both two are separate things and it will decrease understandability
of modules.

So what I am planning is something like :

1. Implement LookAt tag
<LookAT>
<longitude></longitude>
<latitude></latitude>
<altitude></altitude>
</LookAt>

with GeoDataLookAt class.

2. Implement BookMark tag
<BookMark>
<name></name>
<description></description>
<LookAt></LookAt>
</BookMark>

with GeoDataBookMark class to hold data.

3. All data which is there in GeoDataBookmark can be reused in
GeoDataPlacemark, so inheritance tree can be look like,

GeoDataObject <- GeoDataFeature <- GeoDataBookmark <- GeoDataPlacemark

and it will do an important task "Fixing Placemark to support
AbstractView/LookAt".

This was all about my though process, now I want to know your suggestions
about this. Please correct me if something is wrong.

Regars,
Gaurav__
