- Testing DSpace 5.9 with Tomcat 8.5.37 on my local machine and I see that Atmire's Listings and Reports still doesn't work
- After logging in via XMLUI and clicking the Listings and Reports link from the sidebar it redirects me to a JSPUI login page
- If I log in again there the Listings and Reports work... hmm.
- The JSPUI application—which Listings and Reports depends upon—also does not load, though the error is perhaps unrelated:

- I notice that I get different JSESSIONID cookies for `/` (XMLUI) and `/jspui` (JSPUI) on Tomcat 8.5.37, I wonder if it's the same on Tomcat 7.0.92... yes I do.
- Hmm, on Tomcat 7.0.92 I see that I get a `dspace.current.user.id` session cookie after logging into XMLUI, and then when I browse to JSPUI I am still logged in...
- I didn't see that cookie being set on Tomcat 8.5.37
- I sent a message to the dspace-tech mailing list to ask
## 2019-01-04
- Linode sent a message last night that CGSpace (linode18) had high CPU usage, but I don't see anything around that time in the web server logs:
```
# zcat --force /var/log/nginx/*.log /var/log/nginx/*.log.1 | grep -E "03/Jan/2019:1(7|8|9)" | awk '{print $1}' | sort | uniq -c | sort -n | tail -n 10

```
- I'm thinking about trying to validate our `dc.subject` terms against [AGROVOC webservices](http://aims.fao.org/agrovoc/webservices)
- There seem to be a few APIs and the documentation is kinda confusing, but I found this REST endpoint that does work well, for example searching for `SOIL`:
```
$ http http://agrovoc.uniroma2.it/agrovoc/rest/v1/search?query=SOIL&lang=en
HTTP/1.1 200 OK
Access-Control-Allow-Origin: *
Connection: Keep-Alive
Content-Length: 493
Content-Type: application/json; charset=utf-8
Date: Fri, 04 Jan 2019 13:44:27 GMT
Keep-Alive: timeout=5, max=100
Server: Apache
Strict-Transport-Security: max-age=63072000; includeSubdomains
Vary: Accept
X-Content-Type-Options: nosniff
X-Frame-Options: ALLOW-FROM http://aims.fao.org
{
"@context": {
"@language": "en",
"altLabel": "skos:altLabel",
"hiddenLabel": "skos:hiddenLabel",
"isothes": "http://purl.org/iso25964/skos-thes#",
"onki": "http://schema.onki.fi/onki#",
"prefLabel": "skos:prefLabel",
"results": {
"@container": "@list",
"@id": "onki:results"
},
"skos": "http://www.w3.org/2004/02/skos/core#",
"type": "@type",
"uri": "@id"
},
"results": [
{
"lang": "en",
"prefLabel": "soil",
"type": [
"skos:Concept"
],
"uri": "http://aims.fao.org/aos/agrovoc/c_7156",
"vocab": "agrovoc"
}
],
"uri": ""
}
```
- The API does not appear to be case sensitive (searches for `SOIL` and `soil` return the same thing)
- I'm a bit confused that there's no obvious return code or status when a term is not found, for example `SOILS`:
```
HTTP/1.1 200 OK
Access-Control-Allow-Origin: *
Connection: Keep-Alive
Content-Length: 367
Content-Type: application/json; charset=utf-8

Keep-Alive: timeout=5, max=100

Strict-Transport-Security: max-age=63072000; includeSubdomains

"@id": "onki:results"
},
"skos": "http://www.w3.org/2004/02/skos/core#",
"type": "@type",
"uri": "@id"
},
"results": [],
"uri": ""
}
```
- I guess the `results` object will just be empty...
- Another way would be to try with SPARQL, perhaps using the Python 2.7 [sparql-client](https://pypi.org/project/sparql-client/):
```
$ python2.7 -m virtualenv /tmp/sparql
$ . /tmp/sparql/bin/activate
$ pip install sparql-client ipython
$ ipython
In [10]: import sparql
In [11]: s = sparql.Service("http://agrovoc.uniroma2.it:3030/agrovoc/sparql", "utf-8", "GET")
In [12]: statement=('PREFIX skos: <http://www.w3.org/2004/02/skos/core#> '
...: 'SELECT '
...: '?label '
...: 'WHERE { '
...: '{ ?concept skos:altLabel ?label . } UNION { ?concept skos:prefLabel ?label . } '
...: 'FILTER regex(str(?label), "^fish", "i") . '
...: '} LIMIT 10')
In [13]: result = s.query(statement)
In [14]: for row in result.fetchone():
...: print(row)
...:
(<Literal "fish catching"@en>,)
(<Literal "fish harvesting"@en>,)
(<Literal "fish meat"@en>,)
(<Literal "fish roe"@en>,)
(<Literal "fish conversion"@en>,)
(<Literal "fisheries catches (composition)"@en>,)
(<Literal "fishtail palm"@en>,)
(<Literal "fishflies"@en>,)
(<Literal "fishery biology"@en>,)
(<Literal "fish production"@en>,)
```
- The SPARQL query comes from my notes in [2017-08]({{< relref "2017-08.md" >}})

<li>The API does not appear to be case sensitive (searches for <code>SOIL</code> and <code>soil</code> return the same thing)</li>
<li>I&rsquo;m a bit confused that there&rsquo;s no obvious return code or status when a term is not found, for example <code>SOILS</code>:</li>
