[Archivesspace_Users_Group] Example of programmatically updating /agents/people via REST?

[Doiel, Robert]

Hello Mark,

When I wrote my migration tool the biggest problem with /agents/people turned out to be the lock_version fields. If they are not correctly set (the value from the previous read) then the whole thing is rejected.  I can’t show you this in Python or Ruby as the tools I wrote are in Go and JavaScript but I am pretty sure you might be able to get an idea from them.  The tools here at Caltech can be seen at https://github.com/caltechlibrary/cait. The place to start would be the JavaScript example fix-agents-peoples.js.  The JavaScript uses the underlying Go code to get a JSON blob representing a person then updates the agents name fields and writes it back.

Sorting out the model structure I found using Stephen Dolan’s jq to be vary helpful. I would curl the request to get the agent I wanted to update. Tweak the resulting JSON, check it with jq, then send it back via curl.

I found the following very helpful too

+ https://www.youtube.com/watch?v=z0HR46q4F8o - A screen cast of using the API via curl
+ http://archivesspace.github.io/archivesspace/api/ which is a JavaScript generate page that shows the models (it’s not the page that lists in Googling “ArchivesSpace REST API”)

All the best,

Robert
(P.S. This week’s a bit busy but I’ll see if I can whip up a Python demo showing what you ask too)
