Globsyn's Web 2.0 Practice Team has implemented blogs (open source component designed and developed) for various WEB applications where each post is usually 'tagged' with a keyword or two, allowing the subject of the post to be categorized within the system so that when the post becomes old it can be filed into a standard, theme-based menu system. Clicking on a post's description, or tag (which is displayed below the post), will take you to a list of other posts by the same author on the blogging software's system that use the same tag. The permalink is a permanent URL which is generated by the blogging system and is applied to a particular post. If the item is moved within the database, e.g. for archiving, the permalink stays the same. Crucially, if the post is renamed, or if the content is changed in any way, the blog content is regularly filed so that only the latest content is available from the homepage. This means that returning to a blog's homepage after several weeks or months to find a particular piece of content is potentially a hit and miss affair. gBlog also facilitates syndication, in which information about the blog entries, for example, the headline, is made available to other software via RSS and, increasingly, Atom. This content is then aggregated into feeds, and a variety of blog aggregators and specialist blog reading tools can make use of these.
