The real portfolio

As part of my application for jobs as I come close to graduating from university I want to create a complete portfolio of my work to date. However, being someone who is quite concerned with keeping things theoretically neat I want to start by working out a good way to make a portfolio who's format I can adjust in the future without any costs and who's content can be added to without reprinting. I also think it is important to be able to control access and create versions that cater specially to different viewers. For example there are certain projects that pertain more directly to certain companies or interested parties that I may show my folio to so I would like a good way to filter things without generating a new special edition of the data set.

I would also like to do it all online so that it's state is independent of the state of my current computer and it is more easy to access for a greater number of people.

The first solution that comes to mind is one like my recent project summarising my work and experience in China, My China Reflections, however I am not sure that this is the ideal approach. This project was held on a blog and subsequently suffers from the lack of depth that the blog information model seems designed to handle. I am interested in creating my own information model but I am not familiar enough with any software to do that at the time being. For this reason my first step is to look into various possible ways to deal with the information and attributes of the information model that I eventually use that would be useful.

Please comment if you have anything at all to add. Thanks.
