<li>I&rsquo;m testing dspace-statistics-api with our DSpace 7 test server
<ul>
<li>After setting up the env and the database the <code>python -m dspace_statistics_api.indexer</code> runs without issues</li>
<li>While playing with Solr I tried to search for statistics from this month using <code>time:2022-09*</code> but I get this error: &ldquo;Can&rsquo;t run prefix queries on numeric fields&rdquo;</li>
<li>I guess that the syntax in Solr changed since 4.10&hellip;</li>
<li>This works, but is super annoying: <code>time:[2022-09-01T00:00:00Z TO 2022-09-30T23:59:59Z]</code></li>

<ul>
<li>I tested the controlled-vocabulary changes on DSpace 6 and they work fine
<ul>
<li>Last week I found that DSpace 7 is more strict with controlled vocabularies and requires IDs for all node values</li>
<li>This is a pain because it means I have to re-do the IDs in each file every time I update them</li>
<li>If I add <code>id=&quot;0000&quot;</code> to each, then I can use <a href="https://vim.fandom.com/wiki/Making_a_list_of_numbers#Substitute_with_ascending_numbers">this vim expression</a> <code>let i=0001 | g/0000/s//\=i/ | let i=i+1</code> to replace the numbers with increments starting from 1</li>

<ul>
<li>That IP is on Internet Vikings aka Internetbolaget and we are already marking that subnet as &lsquo;bot&rsquo; for XMLUI so most of these requests are HTTP 503</li>

<li>On another note, I&rsquo;m curious to explore enabling caching of certain REST API responses

<li>I estimate that it will take about 1GB of cache to harvest 100,000 items from CGSpace with OpenRXV (10,000 pages)</li>

<li>Upload 682 OICRs from MARLO to CGSpace

<li>We had tested these on DSpace Test last month along with the MELIAs, Policies, and Innovations, but we decided to upload the OICRs first so that other things can link against them as related items</li>

<li>This effectively makes our cache half as effective, but hopefully as more people start harvesting the number of requests handled by it will go up</li>
<li>I will enable this on CGSpace and email Moises from CIP to check if their harvester is working</li>

<ul>
<li>Update welcome text on CGSpace after our meeting last week</li>
<li>I found another dozen or so ORCIDs for top authors on ILRI&rsquo;s community on CGSpace and tagged them (~1,100 more metadata fields)</li>
<li>Last week we discussed moving <code>cg.identifier.googleurl</code> to <code>cg.identifier.url</code> since there is no need to treat Google Books URLs specially anymore as far as we know
<ul>
<li>I made the changes to the submission form and the XMLUI item displays, then moved all existing metadata in PostgreSQL:</li>
</ul>
</li>
</ul>

</span></span><span style="display:flex;"><span>UPDATE 1137
</span></span></code></pre></div><ul>
<li>Then I deleted <code>cg.identifier.googleurl</code> from the metadata registry</li>
<li>Meeting with Salem, Svetlana, Valentina, and Abenet about MEL depositing to CGSpace for the initiatives
<ul>
<li>Submitting to a collection without a workflow works as expected, and we can even select another collection (with a workflow) to map the item to from the MEL submission</li>
<li>The three minor issues we found were:
<ul>
<li>MEL still doesn&rsquo;t send the bitstream</li>
<li>MEL sends metadata with a download URL on mel.cgiar.org</li>
<li>MEL sends a JPEG that says &ldquo;no thumbnail&rdquo; when an item doesn&rsquo;t have a thumbnail</li>
</ul>
</li>
<li>I still need to send feedback to the group</li>
</ul>
</li>
</ul>
<h2 id="2022-09-27">2022-09-27</h2>
<ul>
<li>Find a few more ORCID identifiers missing for ILRI authors and add them to the controlled vocabulary and tag the authors on CGSpace</li>
<li>Moises from CIP says the WordPress importer worked fine with the current nginx proxy cache settings so it seems adding the HTTP Accept header to the cache key worked</li>
<li>Update my DSpace 7 environments to 7.4-SNAPSHOT
<ul>
<li>I see they have added thumbnails in some places now</li>
<li>Oh nice, they also added the &ldquo;recent submissions&rdquo; to the home page</li>
</ul>
</li>
<li>While talking with Salem about the MEL depositing to CGSpace we discovered an issue with HTTP DELETE on <code>/items/{item id}/bitstreams/{bitstream id}</code> or <code>/bitstreams/{bitstream id}</code>
<ul>
<li>DSpace removes the bitstream but keeps the empty <code>THUMBNAIL</code> bundle, which breaks the display in XMLUI</li>
</ul>
</li>
<li>Meeting with Enrico et al about PRMS reporting for the initiatives</li>
</ul>
<h2 id="2022-09-28">2022-09-28</h2>
<ul>
<li>I was reading the source code for DSpace 6&rsquo;s REST API and found that it&rsquo;s <a href="https://github.com/DSpace/DSpace/blob/dspace-6.4/dspace-rest/src/main/java/org/dspace/rest/ItemsResource.java#L427">not possible to specify a bundle while POSTing a bitstream</a>
<ul>
<li>I asked Salem how they do it on MEL and he said they pretend to be a human and do it via XMLUI!</li>
</ul>
</li>
<li>I added a few new ILRI subjects to the input forms on CGSpace
<ul>
<li>Both &ldquo;bushmeat&rdquo; and &ldquo;wildlife conservation&rdquo; are AGROVOC terms, but &ldquo;wild meat&rdquo; is not</li>
<li>The distinction ILRI would like to start making is:</li>
</ul>
</li>
</ul>
<blockquote>
<p>Meat comes from any animal, and when at ILRI we specifically make
reference to it in the context of livestock. However the word bushmeat
refers to illegal harvesting of meat. wild meat is being used as legal
harvesting of meat from wildlife and not from livestock.</p>
</blockquote>
<ul>
<li>I added a few more CGIAR authors ORCID identifiers to our controlled vocabulary and tagged them on CGSpace (~450 more metadata fields)</li>
<li>Talking to Salem about ORCID identifiers, we compared list and they have a bunch that we don&rsquo;t have:</li>

<li>So it seems we&rsquo;ve seen this bot before and the total number is much higher than the 10,000 this month</li>
<li>I had a call with Salem and we verified that the nginx cache bypass for clients who provide a JSESSIONID fixes their issue with updating items/bitstreams from MEL
<ul>
<li>The issue was that they delete all metadata and bitstreams, then add them again to make sure everything is up to date, and in that process they also re-request the item with all expands to get the bitstreams, which ends up getting cached and then they try to delete the old bitstream</li>
</ul>
</li>
<li>I also noticed that someone made a <a href="https://github.com/DSpace/DSpace/pull/8343">pull request to enable POSTing bitstreams to a particular bundle</a> and it works, so that&rsquo;s awesome!</li>
