Digital content can be just about anywhere, and yet nowhere. What turns the collection of bytes into meaningful content - is a bundle of contexts: syntactical, logical, physical, theoretical, psychological and cultural context.
In the online terminology, a tag is a non-hierarchical keyword or term assigned to a piece of information. This type of metadata - data over data - helps describe an item and allows it to be easily found again by browsing or searching. Tags are chosen informally and personally by the item's creator or by its viewer.
Geo-tags, broadens and focuses the description of information, as being a process of attaching geographical identification to various media, that can help users find a wide variaty of geographical location-specific information. The Geo-tagging is usually based on physical addresses, place names or latitude and longitude coordinates.
GRAZEit enables describing information by attaching metadata that can help users find location-based information on the net: instead of latitude and longitude coordinates or physical address - simply a URL.
The users' whereabouts in a specific location, in our case on a specific webpage, creates contexts that give practical meaning to relevant digital content from other places in the web.
