The primary reason to add the WordPress umbrella over the Visualization application was to enable ‘tagging’ of content (primarily charts). Another reason to move to WordPress was to enable quick changes to the look and feel as using the large repository of WordPress themes and plug-ins.
There are two ways of organizing content in WordPress: using tags or categories. We are using tags mainly for Observatory contnent. Categories are also being used but the bulk of categorization is being done using tags. Later, if the administrators can re-tag/re-categorize the content.
