Yes, sadly the Composer has been deprecated long ago, still if you want to read more about it you can find here more information:

Hope you find this useful.

Difficult to play with it due to Composer no longer being available but trying to get the logic behind it.
One thing that would seem odd is to store age as an integer. if you write an age it would never update and hence after one year all the data would be outdated. Wouldn’t it be better to have a date of birth stored and compare to current date so that the age field automatically updates to whatever it is on that day? Sorry for newbie question.

Hi @filip and @thecil,

a pity that we just can watch and not play around with the tool, although I think I got the idea.
By the way, as others said before, 50 isn’t old - I tell you, it’s new beginning !! :crazy_face:
So enjoy the next 25 years!!

I have tried to install Hyperledger Composer locally following this page: https://medium.com/kago/tutorial-to-install-hyperledger-composer-on-windows-88d973094b5c#
And I kind of succeeded - I got to the My Business Networks screen. However from there on sadly it was not very operational.

Hi.
So if i understend this right when you have a:
o string (here comes a word)
if you have a
o integer (here comes a number)
is it right?

yes, string is the keyword used for words/letters in a variable. While integer is for numbers (negative and positive), uint for example is unsigned integer (only positive numbers).
