OK, I'll try and give some points - which are all technical; we are
comparing different techniques; succesful EDI is of course not only
depending on technique ;-)
- JSON is 'self-descriptive': the name of the field is in the file.
This make is easier to read/write for an application because you do
not have to retrieve fields and add a name; you have this all at once.
- In a translator you do not need to specify the layout of the inhouse
JSON file which just saves work.
- If you add a field or entity in the inhouse file this is easier in
JSON; the added field it does no harm if it is not used in the
application.
- if a format of a field changes in fixed format, this is quite
cumbersome because all the positions of the field shift (I can not
tell how often I counted positions).
As I said, I have never seen a 'JSON inhouse format'.
But I remember using a odd inhouse format which looked like this:
$entity1
fieldname1, contents
fieldname2, contents
fieldname3, contents
$entity2 #can be 'nested' under entity1; similar to fixed format
fieldname1, contents
etc
kind regard,
Henk-Jan Ebbers
The format was quite succesfull; programmers loved it.
