1) location is the primary key of a bundle within a framework instance. Each installed bundle must have a unique location. The location is supplied by the management agent installing the bundle. That is, location is a locally supplied identity. Location is often a URL from which an inputstream can be created to install or update a bundle. In this case, location is necessarily a locally assigned value since it may be a www address. Location must not change for an installed bundle. That is updating the bundle will never change the location.
2) The (bundle symbolic name, bundle version) tuple is a secondary key of a bundle within a framework instance. Each installed bundle must have a unique tuple. The tuple is assigned by the developer of the bundle. That is, the tuple is a global identity for the bundle since it does not matter from where the bundle is obtained. The tuple value is contained within the bundle's manifest and thus the tuple value can change (completely) when the bundle is updated. There is no correlation between the value of the location and the tuple since they are assigned by different entities.
