I'd be very interested to get your code, especially with 301 and 302 redirects. My initial runs have resulted in redirects stalling the status code response, preventing my program from moving forward. Getting the status code of the link being redirected to
would be a big help.<br>
<br>
I should also mention that any solution I make needs to be replicable to other faculty/staff in our library - so access to the database may not be consistent in the future. I'm thinking of a scenario where 5 years from now, some people may want to run this
report again but I may not be working for the library anymore. If that's the case, working to export from ArchivesSpace might be the better long-term, no-fusses solution.<br>

<div>Hi Corey, <br>
</div>
<div><br>
</div>
<div>Earlier this year we did something similar. We started by extracting all xlink:href from the EAD corpus using xslt. (EAD is our go-to data source since we always have a constantly updated set, as we use them to automatically publish our finding aids.)
We did not do an additional regex search for non-encoded URLs, but that's not a bad idea. The result was over 15,000 links. Each was recorded with bibid, container id (if any), and link text and title (if any). To check them, my colleague ran them through
a Python script to get the response code, and if the response was 301/302, retrieve the redirect location and secondary response. This produced some interesting results, and resulted in a fair amount of remediation work to do.
<br>

<div>If this sounds on point, I can try to find and share the code we used.<br>

I have access to our staging database, but not production. I'm not sure our sysadmins will allow me to play around in the prod database, unless they can assign me read only maybe? Pulling the file_uri values for file_version would be much more efficient. However,
I'm not just looking to check digital object links, but also any links found within collection and archival object level notes, either copied straight into the text of the notes or linked using the <extref> tag. I could probably query the database for that
info too.<br>

<p>Hi Corey – </p>
<p>Do you have access to query the database, as a starting point, instead of EAD? We were able to pull the file_uri values from the file_version table in the database. Our sysadmin then checked the response codes for that list of URI, and we referred issues
out to staff working on those collections. Some corrections can be made directly by staff, or for long lists, you could include the digital_object id and post updates that way.</p>

Hello, this is Corey Schmidt, ArchivesSpace PM at the University of Georgia. I hope everyone is doing well and staying safe and healthy.<br>
<br>
Would anyone know of any script, plugin, or tool to check for invalid URLs within resources? We are investigating how to grab URLs from exported EAD.xml files and check them to determine if they throw back any sort of error (404s mostly, but also any others).
My thinking is to build a small app that will export EAD.xml files from ArchivesSpace, then sift through the raw xml using python's lxml package to catch any URLs using regex. After capturing the URL, it would then use the requests library to check the status
code of the URL and if it returns an error, log that error in a .CSV output file to act as a "report" of all the broken links within that resource.<br>
<br>
The problems with this method are: 1. Exporting 1000s of resources takes a lot of time and some processing power, as well as a moderate amount of local storage space. 2. Even checking the raw xml file takes a considerable amount of time. The app I'm working
on takes overnight to export and check all the xml files. I was considering pinging the API for different parts of a resource, but I figured that would take as much time as just exporting an EAD.xml and would be even more complex to write. I've checked Awesome
ArchivesSpace, this listserv, and a few script libraries from institutions, but haven't found exactly what I am looking for.<br>
<br>
Any info or advice would be greatly appreciated! Thanks!<br>
<br>
Sincerely,<br>
<br>
Corey</span></p>
