Alida provides a framework for automatic documentation of data analysis procedures.
Operators
The operator concept is the main ingredient of Alida. By developing such operators, the processing steps
of an analysis procedure can be linked to a directed graph structure, which allows self-documentation
of the entire analysis process. Each resulting data object, being the result of a certain operator or sequence
of operations, is associated with a history graph in XML format.
History Graphs
Analysis procedures inherently define an acyclic directed graph data structure which Alida make explicit in terms of
history graphs. They define visual representations of data analysis procedures subsuming operators, their order of
invocation and their parameters. The graphs allow for easy archival and later reconstruction of analysis procedure and
can be visualized in a comfortable manor with Chipory.
Chipory
Chipory is a comfortable graph visualization tool for exploring graph data structures. It is based on Chisio, however,
extended to meet the special requirements of Alida's history graphs.
