XAYAgui_001 An Interface for Thinking with Data
==============================================
XAYAgui is a Pythonic implementation of the Graph Abstraction Logic (GAL)
design principles. GAL relationally models information as graphs (an old idea
originating in modern logic) as a "little language" that can embedded
or embellished. It provides a basis for modelling and querying data from
complex systems. Data---> Information--> Knowledge (but wisdom is golden).
GAL was inspired by Robert Ulanowicz's ecological network theory of Ascendency,
Stan Salthe's developmental theory of Hierarchical Systems,
and Charles Peirce's Existential Graphs (a visual method of doing logic).
Hopefully beautiful ideas can lead to pragmatic working code ;-} ...
Xayacore goes frominstances to ontologies,and points inbetween.
One graph to rule them all! And some common sense to bind them ...
Send bugs, fixes, suggestions to mishtu@harmeny.com (Thanks).
