[mapguide-users] Custom FDO Provider

[Chris White]

Traian,
 
I am attempting to extract spatial data stored in our own format within
a SQL Server, with just read capabilities to start with. It should not
be too much of an issue mapping to fdo because out format is (loosely)
based on GML 2. Any info on which fdo interfaces I need to implement
would be appreciated.
 
Thanks in advance,
 
Chris

It certainly is possible and actually not all that hard to write your
own FDO provider. It depends largely on what data you are trying to
access via that provider and how easy it is to map to FDO objects and
APIs. It also depends on if you need to be able to modify data or just
read it for display purposes. If you only need the latter, then you only
need to implement a small-ish subset of the FDO API. If you decide to
give it a shot, I can tell you which FDO interfaces you absolutely need
to implement as a minimum in order to make it work with MapGuide. FYI,
the smallest functioning feature provider I've seen so far is around
2-3000 lines of code (in a single source file), so you are looking at at
least that much work.

Has anyone attempted to write there own fdo provider yet as I'm about to
undertake this task and wondered if you had any advice / where you
started? Most of the documentation seems to be based around using an fdo
provider not writing one.
 
Thanks in advance
