The RB98 criteria for supercells were inferential ( presence of significant tornado or large hail ) , and as stated there , may have either excluded many nontornadic supercells where large hail was not reported , or included non-supercell storms with large hail reports . The project 's data and database must be flexible so that it can be loaded and / or converted to one of several database or repository products . The objects contain linkages between datastreams ( internally managed or external media files ) , metadata ( inline or external ) , system metadata ( including a PID a persistent identifier that is unique to the Repository ) , and disseminators that bind the data objects to behavior objects managed by Fedora that provide software processes ( behaviors ) that can be used with the datastreams . People with stiff joints and muscles due to arthritis of the neck or inflammation of the shoulder joints may develop tension headache . In addition , the database or repository must be accessible to all retrieval methods in use . Interoperability with existing or future database or repository products is required .
