Completing the second block of the first part of the Web Science MOOC you will
- learn that the basic form of the web consisted of 3 main technologies (URI, HTTP, HTML).
- see that the concepts and ideas of each of these technologies wasn't new but the combination of all of them created such a tremandous extra value.
- realize how there where similar systems like the web and why the open (licence) structure of the web as well as compatibility added to the success of the web.
- have implemented a simple web server and web client
- know the basic components of HTML
- understand the importance of the 404 for web scale
- know the most important historical events that influenced the rise of the web
understanding HTTP 1.0
- protocol for requesting files (especially hypertext) from URIs
- HTTP header
- GET, POST,...
- status codes
- content negotiation
- request / response protocol (stateless)
In order to get a better understanding we will implementing a web client and web server which understands HTTP 1.0 and only uses socket libraries.
- the importance of 404 with respect to web scale
- what are the bad design issues of HTTP 1.0
- theoretical discussion of HTTP 1.0 and newer versions
- comparison: Stateless vs connection oriented vs connectionless protocols. Which part of the http protocol belong to which of the concepts?
- linked documents
- The link as a directed edge (again 404 and web scale)
- mark up language
- open format is included into the text to be displayed
- different HTML elements
- RESTful services
as part of http or as a result of the flexibility of http?

- information management systems at CERN
- How the web was deleted
Computing compatibility problems
- Compatibility problems of hardware: TimBL's NextStation
- Microsoft's Internet Explorer (Why is it actually called internet explorer? What a stupid name!) (inventing cookies)
- Netscape (e.g. inventing java script)
- Bill Clinton's role in making the Web high priority.
similar applications and technologies
- compatibility of HTTP with other protocols in order to have all the content accessible
- open, non commercial and free nature of HTTP
