Nowadays we are often offered the opportunity to tag resources. In Facebook I can tag the people in a photo, on my blog I can tag a post, and on del.icio.us I can tag pages I have bookmarked
There are a number of reason why we choose to tag:
- For ourselves, so that we can find resources later. For example Andy may tag an article “toread” to remind himself that he intends to read the article later;
- For others, so that others know what the resource is about. For example Bo may tag a picture “pig” so that others know that it is a picture of a pig;
- For automation, so that other systems know that this resource is meant to be aggregated by them.
Recently we have worked on a project called Muvenation that involves working with teachers and virtual worlds. As the project was starting when I wrote blog posts about it I would use the tag “Muvenation” so I and others would know it was about that project; when I saw web pages that were relevant to the project I would tag them on del.icio.us, when I took relevant inworld screenshots I would post them on flickr and tag them. Thus this Muvenation tag became part of my Digitial Identity and the resources they were linked to also reflect on my Digitial Identity.
