AIDA is a set of defined interfaces and formats for representing common data analysis objects. The project was instigated and is primarily used by researchers in high-energy particle physics.
The goals of the AIDA project are to define abstract interfaces for common physics analysis objects, such as histograms, ntuples (or data trees), fitters, I/O etc. The importance of the interface concept is that a variety of different tools with different implementations can all support a uniform interface: this encourages modular design in data analysis packages and enables users to use their preferred implementation of a certain functionality without having to re-write existing code.
An additional benefit of AIDA is the specification of an XML representation format for data objects, which can be written and read by AIDA-compliant applications. AIDA implementations exist for C++, Java and Python. Conspicuously, the ROOT data analysis package, which dominates current analysis in experimental high-energy physics does not support AIDA, which has resulted in reduced uptake of AIDA, despite its benefits.
