Week 8: Content Sharing

2

Content sharing

• We’ve already looked at some types of content sharing:– Text (blogs, wikis)– Audio (podcasts)– Video (vodcasts)

• As well as these, there are many other types of content that can be shared:– Maps– Bookmarks– Photos– Events– Presentations (slides)– Reviews (books, movies, music)– Feed subscriptions, etc.

3

Content++

• Content has been included in web pages for some time– “Embedded links”

• Content that is posted on “Web 2.0” sites brings some new features:– Content is linked to the creator– Content can be shared to the public– Content can be tagged for easy classification and retrieval

• In content containers

– Comments can be added to content items– You can be notified about new content via RSS feeds

• More about this in the next lecture

Publishing photos with Flickr

10

Using Flickr

• You now must now login with a Yahoo! account– Flickr is owned by Yahoo!

• Upload some pictures:– Select some image from your hard drive– Add tags– Can mark regions of interest and annotate them (“add note”)

• Don’t forget to “choose your Flickr web address” if you want to get a permanent URL

• Then you will get something like:– http://www.flickr.com/photos/yourUserName/ – http://www.flickr.com/people/yourUserName/

11

Flickr is useful for…

• …adding text (descriptions) and tags (keywords) to your pictures

• …organising your pictures:– By date (upload or real “taken on” date using EXIF) - “organizer”

tab– By tag, description, etc. - “search” tab

• …controlling who can access your photos:– Can define each picture’s visibility:

• Private, public, only friends, only family

12

Flickr is also useful for…

• …adding and getting comments on each picture• …social networking:

– You can add (Flickr) friends and exchange messages with them– You can create groups and belong to other’s created groups

• ...uploading and publishing photos in various ways:– Can upload pictures to Flickr by e-mail, or using desktop utilities– Can also publish your pictures to your blog (or website using

“badges”)

13

Flickr disadvantages

• You cannot export your data • You cannot modify (can only rotate) your pictures• You have to pay if you want:

– To allow higher resolution (>800x600) viewing of your images– To create more photo sets (limited to three in the free version)– To be able to post to more than 10 groups– To upload many (large) pictures, since the free version is limited

to 100MB transfer per month

• Similar site called Zooomr– Yes, that’s three Os!

18

How to use del.icio.us

• Register at http://del.icio.us and:– You will get a public URL, and your username will be at the end

of the URL, like http://del.icio.us/Cloudie

• Start adding your favourite URLs:– Add a page, e.g. http://teaching.deri.ie/ and then:

• Add tags (for example: “personal cool nuigalway course student”)

• A tag is a one word descriptor (for example, homePage, myName) so it is probably best to avoid punctuation marks, and you can also use “camelCase” if you like it

• Add buttons for “quick access” to del.icio.us in your browser:– See http://del.icio.us/help/buttons

19

What’s useful or new about del.icio.us?

• Your bookmarks “escape” from your PC:– Become accessible from anywhere– Unlock the hidden data on your desktop

• Your bookmarks are public:– Anyone can view them– You can view everybody else’s

• You can subscribe to other people’s bookmarks• You can send bookmarks to other (registered) people:

– See the “for” and “inbox” tags

20

What else is cool about del.icio.us?

• You can export all your information:– Under “settings”, “export”

• When you want “different boxes”, you can classify your tags using bundles

• You can create / delete your bundles:– Click on “arrange tags”

• A new way of visualisation, the “cloud view”:– You can see a simple list of your tags, or you can view them in a

cloud - try it!
