ISO15926Primer_Context

 Figure 2 starts with someone having a bright idea.  To achieve some business result he has to pass the information to someone else.  If he just sends  the information without context, he is just throwing it all in a bag, hoping the person on the other end can figure it out.
 
-The reason information exchange worked in the past was that we exchanged entire sets of data (for instance, a complete data sheet) where the context was preserved.  But the disadvantage is precisely that: we have to exchange whole sets of data and have humans interpret them item-by-item.  What we want is to be able to let machines exchange information directly without having to rely on context to retain meaning.

 == Why Can't we Just Cut and Paste? ==

 The first and most obvious reason we can't just use a simple Cut and Paste tool is because the data values we want to transfer seldom map to the same (x,y) coordinates on any two data sheets.  In order to know which data values to transfer we have to first know enough about the data sheets and underlaying databases to know which values are involved.
 
-The second reason we can't just use a simple Cut and Paste tool is that mathematical transformations are sometimes required, such as conversion between Metric units and Imperial, as in the data sheet example above.  The third reason is that engineering judgment is often required.  All of these actions are trivial if you have the right context.  We have many thousands of design engineers doing this all day, every day, and generally, they are good at it.  But we rely so much on context to convey meaning that we cannot trust machines to make the right decisions.
