<li>I can’t put my finger on it, but the input form has to be formatted very particularly, for example if your rows have more than two fields in them with out a sufficient Bootstrap grid style, or if you use a <code>twobox</code>, etc, the entire form step appears blank</li>

<li>I spent some time trying to get csv-metadata-quality working with the new Arrow backend for Pandas 2.0.0rc0
<ul>
<li>It seems there is a problem recognizing empty strings as na with <code>pd.isna()</code></li>
<li>If I do <code>pd.isna(field) or field == ""</code> then it works as expected, but that feels hacky</li>
<li>I’m going to test again on the next release…</li>
<li>Note that I had been setting both of these global options:</li>
<li>Peter sent me a list of items that had ILRI affiation on Altmetric, but that didn’t have Handles
<ul>
<li>I ran a duplicate check on them to find if they exist or if we can import them</li>
<li>There were about ninety matches, but a few dozen of those were pre-prints!</li>
<li>After excluding those there were about sixty-one items we already have on CGSpace so I will add their DOIs to the existing items
<ul>
<li>After joining these with the records from CGSpace and inspecting the DOIs I found that only forty-four were new DOIs</li>
<li>Surprisingly some of the DOIs on Altmetric were not working, though we also had some that were not working (specifically the Journal of Agricultural Economics seems to have reassigned DOIs)</li>
<li>For the rest of the ~359 items I extracted their DOIs and looked up the metadata on Crossref using my <code>crossref-doi-lookup.py</code> script
<ul>
<li>After spending some time cleaning the data in OpenRefine I realized we don’t get access status from Crossref</li>
<li>We can imply it if the item is Creative Commons, but otherwise I might be able to use <ahref="https://unpaywall.org/products/api">Unpaywall’s API</a></li>
<li>I found some false positives in Unpaywall, so I might only use their data when it says the DOI is not OA…</li>
<li>During this process I updated my <code>crossref-doi-lookup.py</code> script to get more information from Crossref like ISSNs, ISBNs, full journal title, and subjects</li>

<li>After updating my Crossref lookup script and checking the remaining ~359 items I found a eight more duplicates already existing on CGSpace</li>
<li>Wow, I found a <ahref="https://programminghistorian.org/en/lessons/fetch-and-parse-data-with-openrefine#example-1-fetching-and-parsing-html">really cool way to fetch URLs in OpenRefine</a>
<ul>
<li>I used this to fetch the open access status for each DOI from Unpaywall</li>
</ul>
</li>
<li>First, create a new column called “url” based on the DOI that builds the request URL. I used a Jython expression:</li>
<li>Then create a new column based on fetching the values in that column. I called it “unpaywall_status”</li>
<li>Then you get a JSON blob in each and you can extract the Open Access status with a GREL like <code>value.parseJson()['is_oa']</code>
<ul>
<li>I checked a handful of results manually and found that the limited access status was more trustworthy from Unpaywall than the open access, so I will just tag the limited access ones</li>
</ul>
</li>
<li>I merged the funders and affiliations from Altmetric into my file, then used the same technique to get Crossref data for open access items directly into OpenRefine and parsed the abstracts
<ul>
<li>The syntax was hairy because it’s marked up with tags like <code><jats:p></code>, but this got me most of the way there:</li>
<li>Meeting with FAO AGRIS team about how to detect duplicates
<ul>
<li>They are currently using a sha256 hash on titles, which will work, but will only return exact matches</li>
<li>I told them to try to normalize the string, drop stop words, etc to increase the possibility that the hash matches</li>
</ul>
</li>
<li>Meeting with Abenet to discuss CGSpace issues
<ul>
<li>She reminded me about needing a metadata field for first author when the affiliation is ILRI</li>
<li>I said I prefer to write a small script for her that will check the first author and first affiliation… I could do it easily in Python, but would need to put a web frontend on it for her</li>
<li>Unless we could do that in AReS reports somehow</li>
<li>Apply a bunch of corrections to authors, affiliations, and donors on the new items on DSpace Test</li>

<li>I offered to CKM that we increase them again to 400 or 600px</li>

<li>Seems like 600px is 3 to 4 times larger file size, so maybe we should shoot for 400px or 500px
<li>On that note, I also re-worked the XMLUI item display to show larger thumbnails (from a max-width of 128px to 200px)</li>
<li>And now that I’m looking at thumbnails I am curious what it would take to get DSpace to generate WebP or AVIF thumbnails</li>
<li>Peter sent me citations and ILRI subjects for the 350 new ILRI publications
<ul>
<li>I guess he edited it in Excel because there are a bunch of encoding issues with accents</li>
