[Archivesspace_Users_Group] Find by ID API call

Tue Dec 13 17:14:51 EST 2022

Thanks, Corey,
This one finally worked for me, based on using the --data-urlencode option and seeing what it did, along with the URL that worked for you (which included the host but not the http:// part).

                http://ourhost.com:8089/repositories/5/find_by_id/archival_objects?ark[]=ark%3A%2F9999%2F119460<http://ourhost.com:8089/repositories/5/find_by_id/archival_objects?ark%5b%5d=ark%3A%2F9999%2F119460>

Embarrassingly, I was using POST instead of GET, which didn't help my testing of the other aspects of the find_by_id API.

I have to say that the answer here was not at all obvious. There was no indication in the doco that you would have to encode the ARK, although all ARKs will have a colon and slashes. Most of our component_id's also have slashes and that wasn't indicated for them, either. Perhaps it's obvious to everyone else, but I have no idea why we include the "[]" after "ark". I guess you can use multiple values or something, but there's no indication of how that is done. It's great to have the full doco for all the APIs, but most of it is pretty cryptic. A few examples of actually use of them would really go a long way. I guess the fact that not so many sites are using ARKs is part of the problem here.

In any case, thank you very much for your help. I'm on my way now and that's down to you.

Regards,
Alan

Hey Alan,

Big caveat first: we don't use ARKs where I work, so I'm flying a little blind here. I enabled ARKs on our testing space just to see if I could replicate your request. Here's what I tried and it returned the correct archival object:

curl -H "X-ArchivesSpace-Session: $SESSION" "https://our_api_url/repositories/2/find_by_id/archival_objects?ark[]=www.testarkurl.com/ark:/YLTAD111/51/37;resolve[]=archival_objects<https://our_api_url/repositories/2/find_by_id/archival_objects?ark%5b%5d=www.testarkurl.com/ark:/YLTAD111/51/37;resolve%5b%5d=archival_objects>"

I added an external ARK URL to the archival object and put www.testarkurl.com/ark:/YLTAD111/51/37<http://www.testarkurl.com/ark:/YLTAD111/51/37> in that field. Are you using something like this or trying to access internal ARKs? If it's internal, I don't have a way to test that, I'm afraid. Though it seems like the following requests are constructed properly:

http://ourhost.com:8089/repositories/5/find_by_id/archival_objects?component_id[]=YLTAD111/51/37<http://ourhost.com:8089/repositories/5/find_by_id/archival_objects?component_id%5b%5d=YLTAD111/51/37>
http://ourhost.com:8089/repositories/5/find_by_id/archival_objects?ref_id[]=15a419a9464353be174f77bdc8f38874<http://ourhost.com:8089/repositories/5/find_by_id/archival_objects?ref_id%5b%5d=15a419a9464353be174f77bdc8f38874>   (our ref_ids look something like this usually: "ref36_286", that looks like the container_id found in an EAD export)

If you're still getting a 404 error, I might also try using the "--url-encode" parameter to see if that helps. Dave Mayo at Harvard pointed me in this direction which works great for the find_by_id endpoint for resources. Using that would look something like:

curl -H "X-ArchivesSpace-Session: $SESSION" -G http://ourhost.com:8089/repositories/5/find_by_id/archival_objects --data-urlencode 'component_id[]=YLTAD111/51/37'

If you do find a solution, would you mind sharing it with the listserv or me? I wrote the API cURL and Python examples for that endpoint and I couldn't find anyone using ARKs to build an example from. Adding that would be the last piece of the puzzle for that documentation.

Hope this helps,

Corey

Subject: [Archivesspace_Users_Group] Find by ID API call

[EXTERNAL SENDER - PROCEED CAUTIOUSLY]
Hi ArchivesSpace folks,
I've been trying to get the find_by_id API call to work and haven't had any luck. What I really want is to be able to find archival objects by ARK, but I tried the other types of IDs to see if they would work and tell me something useful. But I can't get any of them to work. We're on version 3.2.0. I have a program that establishes a connection and gets a session ID, then sends off the API call. When the same program sends this search API, it works:

http://ourhost.com:8089/search?q=component_id:"YLTAD111/51/37<http://ourhost.com:8089/search?q=component_id:%22YLTAD111/51/37>" OR component_id:"YLTAD111/51/38" OR component_id:"YLTAD111/51/39"&page=1

Here's what I have tried:

Every single call returned a 404 error. Can anyone tell me what I'm doing wrong? I'll feel stupid if it's obvious, but I'll still be thankful. Thanks so much!

Alan
