Tags

June 16, 2006

Last night I had a very interesting unworkshop session, where I really learned a lot! During the day I was trying to figure out what tags are and I was totally lost. But then in the evening I had this wonderful session and thanks to Jay, Harold and my “classmates” I now understand it quite well. I will try to explain it in my words:

Tags are something like favourites in the Windows Toolbar, just that they are not listed within the IE’s Favourites window but on a webpage. So in general this webpage collects all my links that are interesting for me and subdivides them into categories that I can chose. Have a look at my tags at del.icio.us/carosonne to see how it looks like.

Here a screenshot to make you understand easier:

 

This is the main page where it shows all my favourites
This is the main page where it shows all my favourites listed on the left hand side.On the right hand side you can see my tags, i.e. my categories under which my favourites are saved. As you can see I have 7 tags there. It also shows me how many pages/links can be found under which tag.

If I chose a certain tag, like “unworkshop” it shows me just the links that have been categorized under it:

Here it shows me all links that are related to this special topic. Furthermore it shows me related tags. Sometimes a link is not just saved under one tag. For example our Unworkshop aggregator page is also saved under the tag “aggregators”. Delicious shows me these related tags as well. And of course all my tags to quickly change between them.

I think tags are a very useful tool to manage and store knowledge. It’s not like the favourites where you might lose the overview when you have too many links. Furthermore it gives the opportunity to save your links under different tags so you can just use the appropriate tag and do not have to search in other categories/folders to find it. In fact you can just have one bookmark and from there find all others that you need!

Aggregators and RSS

June 13, 2006

I have to admit that during the course when Jay told us first about aggregators and RSS I was really confused and didn't really get the whole sense out of it. But thanks to Angelika I got to this wonderful page and I was able to go through it. Now I'm little into it and think I will be able to explain what aggregateors are and how they can be used.

An aggregator is like an invisible helper that keeps you updated about what's happening on selected webpages. Due to the number of pages that may be of interest people do not have the time to go through all pages everyday to see if there is something new on them. the aggregator can! It collects all the new information on predefined sites and instead of having to look at a houndred pages you just have to look at one to see what has happened in your online world. The technology that makes this things possible is called RSS – Really Simple Syndication. It enables the aggregator to realize when the page has been renewed. Obviously not all pages provide these RSS feeds but the number is growing rapidly.

Aggreagators exist in 2 different designs: the e-mail design where the information is sent via email to the receipient (like google alerts) and the webbased design (like myYahoo! ) that enables the user to watch it's aggregator wherever he/she has access to the internet.

Have a look at our course aggregator to see how it works!


Weblogs or Blogs

June 12, 2006

In the following post I will talk about what I learned about weblogs or blogs through self studies and an online conference with my course mates Angelika and Ulrike. Another "Thank you" to those two and my fellow student Maurizio for all the input!

Definition

A weblog, which is usually shortened to blog, is a web page that serves as a publicly accessible personal journal. It is comprised of links and postings in reverse chronological order, meaning the most recent posting appears at the top of the page. It may consist of the recorded ideas of an individual (a sort of diary) or be a complex collaboration open to anyone. Most of the latter are moderated discussions.
Blogs normally combine text, images, links to other blogs or web pages, and other media related to its topic. Though most of them are primarily textual many show also on photographs, videos or audio.
Authoring a blog, maintaining a blog or adding an article to an existing blog is called blogging. Individual articles on a blog are called blog posts, posts or entries. A person who posts these entries is called a blogger. Blogs are typically updated daily using software that allows people with little or no technical background to update and maintain the blog Read the rest of this entry »
