<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>
|
|
</ul>
|
|
</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 <a href="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>
|
|
</ul>
|
|
</li>
|
|
</ul>
|
|
</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>An unscientific comparison of duplicate checking Peter’s file with ~500 titles on PostgreSQL 12 and PostgreSQL 14:

<li>I used this to fetch the open access status for each DOI from Unpaywall</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>

<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>Regarding ImageMagick there are a few things I’ve learned
|
|
<ul>
|
|
<li>The <code>-quality</code> setting does different things for different output formats, see: <a href="https://imagemagick.org/script/command-line-options.php#quality">https://imagemagick.org/script/command-line-options.php#quality</a></li>
|
|
<li>The <code>-compress</code> setting controls the compression algorithm for image data, and is unrelated to lossless/lossy
|
|
<ul>
|
|
<li>On that note, <code>-compress lossless</code> for JPEGs refers to Lossless JPEG, which is not well defined or supported and should be avoided</li>
|
|
<li>See: <a href="https://imagemagick.org/script/command-line-options.php#compress">https://imagemagick.org/script/command-line-options.php#compress</a></li>
|
|
</ul>
|
|
</li>
|
|
<li>The way DSpace currently does its supersampling by exporting to a JPEG, then making a thumbnail of the JPEG, is a double lossy operation
|
|
<ul>
|
|
<li>We should be exporting to something lossless like PNG, PPM, or MIFF, then making a thumbnail from that</li>
|
|
</ul>
|
|
</li>
|
|
<li>The PNG format is always lossless so the <code>-quality</code> setting controls compression and filtering, but has no effect on the appearance or signature of PNG images</li>
|
|
<li>You can use <code>-quality n</code> with WebP’s <code>-define webp:lossless=true</code>, but I’m not sure about the interaction between ImageMagick quality and WebP lossless…
|
|
<ul>
|
|
<li>Also, if converting from a lossless format to WebP lossless in the same command, ImageMagick will ignore quality settings</li>
|
|
</ul>
|
|
</li>
|
|
<li>The MIFF format is useful for piping between ImageMagick commands, but it is also lossless and the quality setting is ignored</li>
|
|
<li>You can use a format specifier when piping between ImageMagick commands without writing a file</li>
|
|
<li>For example, I want to create a lossless PNG from a distorted JPEG for comparison:</li>
|
|
</ul>
|
|
</li>
|
|
</ul>
|
|
<div class="highlight"><pre tabindex="0" style="color:#f8f8f2;background-color:#272822;-moz-tab-size:4;-o-tab-size:4;tab-size:4;"><code class="language-console" data-lang="console"><span style="display:flex;"><span>$ magick convert reference.jpg -quality <span style="color:#ae81ff">85</span> jpg:- | convert - distorted-lossless.png
|
|
</span></span></code></pre></div><ul>
|
|
<li>If I convert the JPEG to PNG directly it will ignore the quality setting, so I set the quality and the output format, then pipe it to ImageMagick again to convert to lossless PNG</li>
|
|
<li>In an attempt to quantify the generation loss from DSpace’s “JPG JPG” method of creating thumbnails I wrote a script called <code>generation-loss.sh</code> to test against a new “PNG JPG” method
|
|
<ul>
|
|
<li>With my sample set of seventeen PDFs from CGSpace I found that <em>the “JPG JPG” method of thumbnailing results in scores an average of 1.6% lower than with the “PNG JPG” method</em>.</li>
|
|
<li>The average file size with <em>the “PNG JPG” method was only 200 bytes larger</em>.</li>
|
|
</ul>
|
|
</li>
|
|
<li>In my brief testing, the relationship between ImageMagick’s <code>-quality</code> setting and WebP’s <code>-define webp:lossless=true</code> setting are completely unpredictable:</li>

<li>I’m curious to see a comparison between the ImageMagick <code>-define webp:emulate-jpeg-size=true</code> (aka <code>-jpeg_like</code> in cwebp) option compared to normal lossy WebP quality:</li>

<li>I first <a href="https://github.com/ImageMagick/ImageMagick/discussions/6204">asked a question on their discussion board</a> because I see that the near-lossless option should have been added to ImageMagick sometime after 2020 according to another discussion</li>

<li>Meeting with Maria about the Alliance metadata on CGSpace
|
|
<ul>
|
|
<li>As the Alliance is not a legal entity they want to reflect that somehow in CGSpace</li>
|
|
<li>We discussed updating all metadata, but so many documents issued in the last few years have the Alliance indicated inside them and as affiliations in journal article acknowledgements, etc, we decided it is not the best option</li>
|
|
<li>Instead, we propose to:
|
|
<ul>
|
|
<li>Remove <code>Alliance of Bioversity International and CIAT</code> from the controlled vocabulary for affiliations ASAP</li>
|
|
<li>Add <code>Bioversity International and the International Center for Tropical Agriculture</code> to the controlled vocabulary for affiliations ASAP</li>
|
|
<li>Add a prominent note to the item page for every item in the Alliance community via a custom XMLUI theme (Maria and the Alliance publishing team to send the text)</li>
