Projects

My public and Open Source projects.
schema2ldif tool
since 2000 A simple tool to convert OpenLDAP schemas to LDIF format (especially while using the Sun Java System Directory Server). The OpenLDAP schemas are a bit more readable and this tool come handy especially when you work with both types of servera and need to maintains schemas over a long time periods.
Clickstore e-commerce solution
2000-2001 E-commerce solution for ISP based on home-brewed Jewels web-application framework (Perl). This was the project of 2000 e-commerce hype, never fully deployed. It is dead now.

Jewels application framework
1999-2001 Web application framewrok for building component applications in object-oriented Perl. Based on XML, embeded-perl templates and quasi-component modules. The mix of the most-popular new technologies that Perl could provide around 2000. As the two primary projects that it was used in (Metropola and Clickstore) died, the framework died as well.

Metropola portal
1999-2000 Internet portal solution based on Jewels application framework. Nice and extensible, but a bit overcomplicated for Slovak e-commerce-hyped-market. It is dead now.

Identity public certificate authority
1999 Prototype of WWW based public Certificate Authority system. It showed that the X.509 technology is technically feasible even while using free products only (It was based on Linux, Apache, OpenSSL and Perl). But soon it became aparent that while there is no problem with technical implementation of X.509, the whole X.509 concept is not well suited for authenticating people on the Internet. I've stopped the project and started looking for other Identity technologies.
