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.

Release party impression

This morning the BIMserver 1.0 release party took place in Delft (the Netherlands). Almost 60 people came to the old watertower to network with other fans and users of the software. Although the 1.0 stable release isn’t online yet (just a moment, it’s a blink of an eye away) the participants got a nice view on the new features. Léon van Berlo gave a short impression on future thoughts from TNO on the open source BIMserver initiative. Martijn Snel from BIMasaService showed a short impression of his services that makes use the open source BIMserver software. In the end Paul Bos from Z33P architects showed a few examples of their use of the software so far.

 

Preparing the BIMserver Breakfast and 1.0 release

For those of you who think we fell asleep: we didn’t. We are working hard on the first 1.0 release candidate. Last week a group of our most valued users have received a private beta of the 1.0 release. They gave us some great feedback on which we are working right now. We plan to publish a first release candidate by the end of August. During the BIMserver Breakfast 2010 on September 1st a group of over 100 people (115 registered until today; and they keep coming) will test the very latest version of the code that day. We hope they do not find too much bugs and give some valuable feedback. If everything goes well the 1.0 stable release will be public in September. We focused on stability in the core and performance of the kernel; but of course there are a lot of new features as well. We even changed (attention: changed may not mean it’s improved….) the GUI. Find a sneak preview below.

New release: v0.8

BIMserver.org: new release, new site, new features!

The open source BIMserver just released a new stable version of their software. The new release is the 0.8 version. A lot has changed since the 0.1 version in March this year. Just some of the new features:

  • 25% speed increase
  • concept of sub-projects
  • improved automatic merging
  • RSS change notification
  • geolocate projects
  • improved multi user support
  • improved web-user-interface
  • google earth network link
  • smart revision management
  • extended query and filter options
  • more details on your revision
  • checkout/update warnings (while concurrent engineering)
  • enhanced read only access
  • enhanced user rights management
  • change finder on revisions
  • export of CityGML, Collada, KML, IFC properties, O3D
  • reference implementation of the CityGML ADE for IFC and BIM
  • get a summary of your model
  • and a lot more….

Some of these features are a direct result of the successful BIMserver Breakfast in November at TNO; some come from the intense contact with some of our users.
This release of the open source bimserver software is, without a doubt, the ‘best bimserver ever’. The team doesn’t stop developing and new plans are already being deployed.
The latest release is now available for download at download.bimserver.org. The demoserver (which was offline during the final stage of development) is back online as well. Check it out on demo.bimserver.org.

Together with the new software, the team also launches their new website. Because our software is stable and professional, our site also needed a more professional layout.
With this new software-release and the new website the BIMserver.org-team and it’s users are ready for the future.

First stable release

About two weeks ago the second release candidate of the bimserver came online. After two weeks of intense testing (by ourselves and by you, the users) we did not find any new bugs. That is why we think it is time to release the first stable version of the bimserver: 0.1.

You can download the builds on http://download.bimserver.org/latest/

When you have some new ideas or feature requests, please let us know so we might implement them in the next release.

We hope to also have a demoserver online in the beginning of next week. The demoserver can be used to play around with the bimserver without having to download and install it.

Update: the downloads are now on  http://opensourcebim.org
