ARIA Needed Repairs
The Issues
• No funding…– Elevates the importance
of service reliability
• Challenges– Code documentation– No system to enforce the use of current
programming practices– User interface
In-code Documentation
• Definition:Comments (text) placed within the code, which are ignored by the program (information only, not running operations).
In-code documentation is used to explain the purpose and functionality behind the code.
• Problem:– Without documentation, developers spend too much time
understanding A.R.I.A instead of maintaining it.
• Solution:– Configured software (IDEA) to produce default documentation.
• Promotes code readability.

ActualCode
Metadata
• Definition: Generated data about data.• Important for the users.• Problems:
– Metadata was entered by hand. – Slow process.
• Solution:– Created scripts that automatically produce metadata
for all imagery on the servers.
Code Abstraction
• Definition: A mechanism used to reduce and factor out implementation details so that one can focus on a few
concepts at a time. • Example: Communication between scripts and database• Solution:
– Mechanism: Hibernate software– Implementation details: SQL queries.
• Increases productivity.
User Interface
Significance of ARIA
• Unique and irreplaceable service
