Subject: Re: [Archivesspace_Users_Group] id=0 error on EAD XML import


Don't be surprised if the import fails again, with the same message but for a 
subrecord, or with a different message. That is because the ArchivesSpace EAD 
importer uses a SAX parser method 
(https://en.wikipedia.org/wiki/Simple_API_for_XML) to read the XML, not a DOM 
(Document Object Model) method. The former is faster and uses less memory, but 
cannot scan an entire XML file for issues and report back with a list of things 
to fix, as the latter would. That is why many people use a pre-import 
validation step to find most of the issues that might occur, without the 
laborious process of creating an import job, waiting for it to fail, then 
re-running.

Harvard have made theirs into a web service which you might find useful:

https://eadchecker.lib.harvard.edu/

I think it is fairly generic (unlike a similar validation script used here 
which imposes editorial restrictions as well.)

Sarah,

I suspect that your EAD file is missing an archdesc/did/unitid field.  This is 
where ArchivesSpace pulls information to create its Identifier field for the 
new Resource (see the attached screenshot), which is a required element.

If you add something there, then I believe it should work.  Here’s an example 
from one of our EAD files, 
https://github.com/YaleArchivesSpace/Archives-at-Yale-EAD3/blob/master/brbl-ead/1000.xml#L80
  (this file is EAD3, but the archdesc/did/unitid construction looks the same 
in EAD2002).

As for why you don’t have one in your file, I expect that’s because the call 
number is stored in a related MARC holdings record, or somewhere else that’s 
not being migrated as part of the MARC XML to EAD conversion (e.g., an 099 
field).

Subject: [Archivesspace_Users_Group] id=0 error on EAD XML import
Hi all,

I’m trying to import a test EAD file that I transformed from MARC XML as a 
trial run for doing this in batches. I knew it would be janky, but I can’t 
narrow in on the specific form of the jank here. When I import I get the error 
below (it’s long, apologies). My two best guesses are
a) ASpace is missing something in each XML element needed to create an ID in 
every one of the JSON fields below?  (which appears to be the entire resource 
record)
b) there’s something missing from the <ead> element in the XML file? (which 
there shouldn’t be – I copied it in manually from an ASpace EAD export)

I know this id_0 error is vague and has confused other people before, but I 
couldn’t find enough information to help me narrow in on the specific issue is 
here.

Thanks!
