I'm a begineer in Alfresco so i'm sorry if someone post it somewhere but i didn't really find what i was looking for.
I will try to explain my problem with my own words. I want to transfer my personalized meta data from my own application (whose read and write documents) to Alfresco but i don't find the correct topic speaking about it. It should be good if when an user upload a document (for exemple a bill), my app read metadatas (for this it's good) then when i put this document on Alfresco, Alfresco keep the personalize medata mentionned before (like invoice number or customber number) and display them.
I tried to use models parameters but i don't really understand how use it and if it could be usefull for my case.
