Key benefits of ABRA
Rich set of data types and functions• Ca. 120 XBRL functions• 16 XBRL instructions
Access to all information located in XBRL documents
Superior processing power compared to 1st generation XML standards and programming APIs• Higher level• Better expressive power w

What are the benefits using a persistent XBRL repository?
Technical issues related to taxonomies• Single initialisation, multiple use• Subset of XML nodes is loaded into memory• Processing outside of database kernel • Processing inside of database kernel• Large result sets
Technical issues related to instances• Element names are indexed (join: concept -> fact)
Novel XBRL applications• Small footprint filing applications based on native XBRL
taxonomies• Processing of multiple taxonomy versions• Excessive use of custom linkbases (views)• Processing/storage of large XBRL GL instances• …
