Internet excites people. Many love it, some frown upon it, many talk about it, but few go beyond conventional knowledge of what is happening in background. The content available on the internet might be the most important thing, but in this seminar we will ignore all the "important" things and focus at the form. The goal is to understand the principles of internet architecture, its different services and the way they

(can) interact.

No philosophical and historical excursions are given (unless deemed necessary) and we do not want to speak about things from the theoretical-only point of view. This seminar is not recommended for hackers (because they already know much more) and not for people who want to acquire practical knowledge on "how to..." (learn HTML, do a website, write scripts, query database etc.) This seminar should serve to enrich understanding of internet and the ways it can be exploited in the real-life (a few examples include: dynamic pages, spiders, OAI harvesting, web services).
