What is a blog?

• A blog, short for weblog (pronounced “we blog”) is an online journal in which the postings are presented in reverse-chronological order.

• Typically blogs contain links to other online resources with additional commentary from the blog’s author.

Why should your department have a blog?

• They’re an easy way to provide information about what’s happening in your department/division.

• Little to no (X)HTML experience necessary.

• Combined with RSS feeds it’s another way for users to receive timely information about what you’re doing.

How do I create a blog?

• There are several services and software packages out there that make creating a blog easy. The two most popular are:

– MoveableType (client)http://www.movabletype.org/

– Blogger (Web service)http://www.blogger.com/

Blogger

What is RSS?

• Depending on who you ask it stands for either “Really Simple Syndication”, “Rich Site Summary”, or “RDF Site Summary”.

• RSS is an XML language for syndicating news items on the Internet.

How does RSS work?

• The author creates an RSS file.

• Users subscribe to the file via an aggregator.

• When the author updates the RSS file, the user is automatically notified of the new items and may read them on their schedule.

Are there different versions of RSS?

• Yes. In fact, there are currently nine different versions:RSS 0.90, 0.91, 0.92, 0.93, 0.94, 1.0, 2.0, 3.0 & Atom Feeds

• Each has different features from the author’s point of view.

• Today’s aggregators support all of the versions transparently.

What does RSS look like?

• “A news aggregator is a software or a remotely hosted service that periodically reads a set of news sources, in one of several XML-based formats, finds the new bits, and displays them in reverse-chronological order on a single page.”— Wikipedia
