+ * RRDtool 1.0.33  Copyright Tobias Oetiker, 1997 - 2001
+ *****************************************************************************
+ * rrd_datalang  A system for passing named and typed parameters between
+ *               the different parts of rrdtool
+ *
+ * In rrdtool thre are a number of places where large and complex
+ * data structures have to be passed from one function to another
+ * eg when rrd_info returns its findings, but also when a function like
+ * rrd_graph get called.
+ *
+ * At the moment function calling is done with an argc/argv type interface
+ * it's special property is that all data is passed as strings, which can lead
+ * to unnecessary conversions being performed when rrdtool functions are called
+ * from a typed language
+ *
+ * Data returns from functions is not standardized at all, which is
+ * efficient in the sense that the data return interface can be tailord to
+ * the specific needs of the function at hand, but it also leads to
+ * increassed probability for implementation errors as things have to be
+ * reinvented for each function. Also adding new functions into all the
+ * language bindings is quite cumbersom.
+ *
+ * Therefore I want to develop a standardized interface for passing named
+ * and typed data into functions and for returning data from functions to
+ * their callers.  I am thinking about working of the code in rrd_info.c ...
+ *
+ * Does anyone have experiance in this field or any pointers to read up on
+ * related work ? Or maybe even an existing library for this ?
+ *
+ * Cheers
