Slow but stable

Many of you probably know the story of the Tortoise and the Hare. After the 1.0 final release of BIMserver.org software this story might appropriate. The 1.0 release was months behind our originally planned releasedate (summer 2010), but it has proven to be a winner in stability. Since the releasedate the download counter is now over 300 downloads. First feedback from users is unanimous: performing slow but stable.
After a release the development team always steps back and has a good look at the core again. Building features is easy, but building them on top of a reliable foundation is the key to stability. After the 1.0 final release we have done the same and created a list of ‘critical’ things for the new core. Until now the performance speed of the software never became an issue, but we cannot ignore this anymore. We even found a sponsor to finance this (name will be public soon…).  That is why ‘lazy loading’ of database objects is on of the first new implementations for the next release. There’s already a lot of work done on that in the source code trunk. Thanks to intensive usage statistics of fanatic users, we also found that alphabetic sorting of projectnames really (yes, really) slowed things down. This kind of userfeedback is very valuable.
The biggest dilemma right now is the choice between releasing a ‘performance update’ that would be 1.0.1 or keep on developing until the 1.1 release is stable. Let us know what you think….

Update: Lots of improvements have been made to speed since this post from 2011!

Release 1.0 final

After several release candidates, the final 1.0 version is now available for download. The team made some final adjustments on the stability, security and usability. The core team received lots of help from enthusiastic developers all over the world.
Feel free to download it from http://download.bimserver.org and try it yourself.

A small selection of stuff we are proud of:

  • ‘Intelligent’ merging of IFC data;
  • User specific RSS feeds;
  • Geolocate your BIM project using openstreetmap;
  • Easier Google Earth link;
  • More query and filter options;
  • Better and more intuitive ‘early warning system’ (for concurrent engineering);
  • Enhanced user control and authentication;
  • ifcZIP upload and download;
  • Tested for ‘BIM in the Cloud’;
  • More options for fine-tuning the configuration;
  • Lots of improvement on the webservice interfaces;
  • Improved security;
  • WebGL browser based IFC viewer (very beta);
  • Better and more monitoring and logging of the server (for administrators);
  • More BIM and GIS integration (geoBIM);
  • Automatic e-mail on clashdetection of your models;
  • COBie export;

Together with the 1.0 we also release our new services. You can find them on http://bimserver.org/service/ To get more professional support for the open source BIMserver software we now offer masterclasses, training and custom development. These services give you more stability on using and implementing the open source BIMserver software in your daily work.

As you might have noticed the documentation of the open source BIMserver is lacking behind. Therefore we are very pleased to tell you that nine Dutch companies and the Netherlands organisation for applied scientific research TNO have started a ‘BIMserver Documentation’ project. This project will take 5 to 6 months and will deliver documentation as pdf, wiki (wiki.bimserver.org) and screencasts on YouTube. At the end of this documentation effort, BIMserver.org and TNO will organise a 4th BIMserver Breakfast (find inspiration on the 2010 site). This will take place in June this year. We are still looking for a location, it you are interested please contact us at breakfast@bimserver.org.

If you have any questions on the 1.0 release, please subscribe to one of the mailinglists and ask your questions there.
