Re: [mapguide-users] Feature Joins absolutely broken in MGOS 2.0.0 RC1
The message The current feature source has no feature classes, and cannot support joins is some strange message that MapGuide Studio spits out due to some caching problem (I believe). If you restart the MapGuide Server after breaking a join, you should be able to repair or create a new join. But you are right about RC2, something seriously broke since 1.2.

Re: [mapguide-users] Differences between UMN MapServer MapGuide...
Jason, I believe MapFish is also 'platform neutral' although there is only really support for MapServer right now (in python IIRC). And MapBuilder is also a development framework based on OpenLayers that is worthy of note and consideration. Cheers Paul On 8-Feb-08, at 5:02 PM, Jason Birch wrote: Hmm. :) You could do a lot without ripping and replacing MapServer by introducing OpenLayers and something like TileCache into your environment. You may want to look at Fusion or MapFish (both of which encapsulate OpenLayers) for a development framework. The nice thing about Fusion is that it's intended to be cross-platform, supporting both MapGuide and MapServer, which would make migration less painful if you did decide to move in the future. The not-so-nice thing is that it's not really available publicly outside of the MapGuide build yet, though there is apparently a plan to move it onto OSGeo infrastructure shortly. Although I don't have any direct experience with MapServer, I am not convinced that you would see better performance with MapGuide than with MapServer if your sole concern is displaying maps. The implementation of a tile caching solution (either MapGuide-native or TileCache) will give you far more bang-for-the-buck if it's done right. Strengths and weaknesses...

In this last case, the loading gif picture stays and if I make zoom in, the new map request sometimes appears, but sometimes not... Do someone experiencing the same trouble?

Re: [mapguide-users] Differences between UMN MapServer MapGuide...
Martin, I disagree with your statement that MapGuide will have far more development and support going forward. Caveat Emptor: The arguments that follow are purely my opinion and are not based in empirical evidence, mostly just my observations having worked with both platforms. Take them with a grain of salt :) MapServer has a large and active developer community spread across individuals and companies that actively improve the software on a daily basis. The MapServer mailing list is large and very helpful, and there is a wealth of user-contributed documentation that grows with every release. MapServer's code base is (in comparison) small, light weight, understandable. It has a relatively low cost of entry for new developers wanting to do stuff. MapGuide, on the other hand, is still largely dependent on a single (but very large) benefactor and has yet to attract additional (core) developers outside of the core team from ADSK. It does have a growing community support infrastructure through this mailing list, which is probably the first step towards growing the development community. The code base is quite large, complex, and not readily understandable by a developer wanting to get started with it. None of this points to 'far more' development or support going forward. I would also argue that MapServer, when properly configured, is faster than MapGuide - at rendering maps. If you need to generate map images for the web, MapServer is generally going to be faster than MapGuide. There are some fundamental differences, though, that need to be understood when making this comparison. 1) Enterprise scalability. It has been said that MapGuide is intended for Enterprise deployment (it supports multiple 'web tier' installations accessing multiple site/support servers potentially through a corporate firewall and distributed across multiple machines. ) with the implication that MapServer is not Enterprise ready. In fact, this is not true and it is equally as possible to set up a similar architecture using MapServer - the main difference is that MapGuide has an installer that sets this up whereas the MapServer solution would have to be designed by a knowledgeable group. When requesting a map image, then, MapGuide has a minimum of three processes that need to be involved - the web server, the 'web tier', and the 'server tier'. MapServer only has two, the web server and the MapServer process. 2) Statefulness. MapGuide is stateful in that you have to establish a session with the server and refer to that session in every request to the server. MapServer is stateless and has no inherent concept of sessions. For applications that require statefulness, MapGuide is typically simpler to use whereas MapServer requires an external framework to make it stateful and that framework adds overhead that makes the performance of MapGuide perhaps better than MapServer. For applications that don't require statefulness (such as serving WMS or Tile requests), MapServer is simply faster because it doesn't have the overhead of statefulness built into its architecture (granted that for WMS and Tiles - MGOS 2.0 only - you can request images directly without needing a session, so that is less of a difference). 3) Optimization. Optimizing for MapGuide and MapServer are very different tasks. For both, you really need to understand the expensive parts of drawing a map - is it accessing the data, filtering it, classifying it, or rendering it - and how to minimize bottlenecks in each of the parts. I would argue that it is more feasible to tune MapServer's performance than MapGuide's. This is, in part, because you have more options with MapServer - different ways of accomplishing the same task. MapGuide is probably more tuned to start with but my experience is that beyond optimizing your data, there isn't much more you can do to tune MapGuide's performance by playing with cartographic options. For data access, MapGuide has FDO, OGR and GDAL support. MapServer supports roughly the same set of data sources, except it doesn't support FDO and hence can't access SDF files. DWF support is not part of FDO, and its actually more of an *output* format than an *input* format. It also requires an activex control to render it, which makes it more-or-less useless to me and many others that need applications that support multiple web browsers and platforms. An FDO connection type for MapServer has been discussed and seems likely to happen at some point, although no specific plans have been made - so MapServer will gain access to SDF at that point. Regarding speed of data access, MapServer is generally considered fastest when used with properly prepared shapefiles, although PostGIS is arguably on par with it. MapGuide is generally considered fastest when used with SDF. I have had very poor
