HELP with data model

We are in the process of developing 'Skills system'. We have a many-to-many recursive Skill entity. That is, Skill can consist of set of skills, which ,in turn, can have many components. For example: PROGRAMMING is a skill and further classifications are C, C++, FORTRAN, SQL etc. SQL can belong to ORACLE, SYBASE etc.

I am sure some of you might have figured this out and found a suitable relational representation. This is very simillar to Bill of Materials problem. Can any one share his/her experience? All suggestions are welcome. Thanks in advance.
