<li>I confirmed the same on CGSpace itself after making one HEAD request</li>

|

<ul>
|
||
<li>I deployed Solr 4.10.4 locally and ran a bunch of requests for bitstreams and they do show up in the Solr statistics log, so the issue must be with re-using the existing Solr core from CGSpace</li>

<li>Still trying to figure out the issue with the items that cause the REST API’s <code>/items/find-by-metadata-value</code> endpoint to throw an exception

<li>I made the item private in the UI and then I see in the UI and PostgreSQL that it is no longer discoverable:</li>

<li>Carlos from LandPortal asked if I could export CGSpace in a machine-readable format so I think I’ll try to do a CSV

<li>In order to make it easier for him to understand the CSV I will normalize the text languages (minus the provenance field) on my local development instance before exporting:</li>

|

<li>Then I exported the whole repository as CSV, imported it into OpenRefine, removed a few unneeded columns, exported it, zipped it down to 36MB, and emailed a link to Carlos</li>
|
||
<li>In other news, while I was looking through the CSV in OpenRefine I saw lots of weird values in some fields… we should check, for example:
|
||
<ul>
|
||
<li>issue dates</li>
|
||
<li>items missing handles</li>
|
||
<li>authorship types</li>
