This is driven by the business case that a dealer may have a specific contract with the organisation, allowing them to sell certain products, and not others as a result of this, they should not see information that is not relevant to their product portfolio. The structure of the hierarchy will be realized as a dynamic web-site. A virtual structure allows the user to determine the way in which documents appear. An example Dynamic View structure is shown in Figure 4, below. Many of these dynamic structures are possible, as they are represented as an ordered set of attribute types that are expanded dynamically as the user navigates that particular view.
Every user has a profile.
This identifies their position in the metadata structures. It defines what information they can see, and what they cannot. The metadata that the author specifies enables the system to determine where in the system the document will be presented to another user. A document can be uploaded at any point to any other point. The document has no concept of location as its placement is determined purely by its metadata.
