There are. If you create a MgResourceService object, you are talking to
the repository.<br>
And MaestroAPI uses this (with a LocalNativeConnection) to talk to the
MapGuide server.<br>
<br>
I have not followed it all the way, but I think that the
MgResourceService is about as close <br>
as it gets, to the repository content. <br>
<br>
Alternatively, you can use DBXml and read the database directly, but
that is a recipie for trouble.<br>

Yes, the http roundtrip time is a beast.<br>
<br>
I think the server is (partly) divided, with one part being a
repository manager.<br>
You can already retrieve resources with calls, and coordinate data with
another.<br>
The MgApi interacts directly with the server, it is still serialized,
but binary.<br>
The MgApi uses the loopback connection, but does not use a webserver,
and has no http headers.<br>
<br>
So you can still do it, but I agree that it would make sense to divide
the different parts more rigidly.<br>

It would be perfect if we had respository manager as a separate API -
representing the actual core. Then, a web-tier API (another component)
leverages repository API to talk over Http with thin clients. So
developers might pick if they want to use either web-tier approach
(i.e. JavaScript) or want to talk via SOAP/linking to the repository
manager directly.</font></span></div>

Silverlight uses GDI+, which also supports hardware acceleration.<br>
I would prefer Silverlight over Java because it intergrates better with
the html DOM (IMO).<br>
<br>
As for codebase, the current viewers are based on Javascript, and they
are limited to <br>
manipulating pre-rendered images.<br>
<br>
The DWF viewer is some of it, but it is still ActiveX based.<br>
I suppose one could make plugins for all browsers, but it still
difficult <br>
to persuade regular web users to install it.<br>
<br>
Since Silverlight/Moonlight is more likely to be installed already,<br>
and backed by Microsoft, it will probably be easier.<br>
<br>
Flash is another option, but it is terribly hard to work with (IMO).<br>

<pre wrap="">I think that there could potentially be a number of alternatives to using an
Active X based viewer. I could see potential also for both Flash or Java to
create a viewer too. One problem with the Active X viewer in relation to the
clients of the company I work for is the security / administrative problem
for our clients. Organisations internet security policies could interfere
with deployment of an Active X control. I would think though that the same
issue would apply to a Java based viewer too. Silverlight might work better
in this regard.
One of the reasons I find the Java option interesting is the availability of
JOGL essentially allowing a Applet or Web Start application to be able to
take advantage of Hardware accelerated graphics. I don't know if any
alternative viewers have been worked on. If much of MapGuide is open source
would that include the viewer? If so it might be possible to start from the
existing viewer source code and port it to another platform.

Such a viewer should be able to achieve performance that is comparable
to the MapGuide 6.5 viewer,
without the need for an ActiveX plugin.
