Hi everyone,

I'm new developer to moodle so I have zero to little experience.

I want to create plugin which will take student's assignment submission, uploads it into evaluation system (some other server), reads output, returns output as feedback in assignment and grades assignment.

I found several options how to do this so far:

1. Creating own Activity module from scratch - a long and complicated way as default Assignment module is 90% of what I need.

2. Duplication and modification of Assignment module - probably easier than option 1 but still dirty work with lot of heavy lifting

3. Local plugin - Probably the correct way. I will describe my idea and correct me if I'm wrong please.

Let's call this plugin as EE-plugin (External Evaluation). EE-plugin will have instances. Each instance will be bound to instance of Assignment module. On submission there is event sent by Assignment/Submission into the moodle with some information. EE-plugin is listener for such events. EE-plugin gets event and does it's thing mentioned earlier.

Use-case: Teacher creates Assignment. Teacher attaches EE-plugin (creates instance of EE-plugin) to specific Assignment.

I think option 3 is the way to go. EE-plugin will have to have simple UI, use Event API. However I have no idea where to start. Is there any resource that handles similar thing? From dev doc, local plugin description suits my use case exactly. Any suggestions, help and tips welcomed.

Thank you all-
