Topas CMS

My main pet project is called Topas, it is a content management system for and my other web properties.
Most Content Management Solutions allow the users to manage their content in a database. The system then creates web pages on the fly when a user hits a web page. There may be some caching involved but the database plays an important role during the display of content to the user.

Topas also saves the content in a database, but it creates stand alone web pages which are served to the user without having to access the database. This has several advantages
The first version was created in 1994 to support my then new web site.
The data was hold in a database system on an Atari ST. It was then transfered to a PC where a lot of Visual Basic code created HTML pages which were then uploaded via FTP to a Unix web server.

In 1995 the data was moved to an MS Access Database and a user interface was created to manage the content. Code then created flat HTML pages and uploaded them to the live server. Various improvement were made over the years, including replacing VBA code with XSLT as the templating language.

Finally in 2005 the system was ported to a web application using with C#. The database was move to SQL Server.
