Department B
A government department has a number of existing applications with minimal support for the storage of digital objects. As the same objects can be found across these internal systems, the idea is to set up a central image bank. All systems access the image bank to retrieve the digital objects.
The key functions include:
Metadata is also loaded into the database. It contains information about the digital object physical attributes but not the metadata. This is to facilitate searching.
A search engine sits over the image bank enabling external users access to the image bank to perform searches.
HTML pages rendered by the department for the public use URLs that reference the digital objects stored in the image bank.
Both internal and external users access the same core set of digital objects.
The internal systems use a many-to-many mapping table to co-ordinate which rows of data in their systems map to which digital objects in the image bank.
