- 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:
|
||||
|
||||
```

||||

|

|

- 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`:
|
||||
|
||||
```
|
||||

```
|
||||
|
||||
- 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`:
|
||||
|
||||
```

```
|
||||
|
||||
- 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)
|
||||
...:
|
||||

|
||||
|

- The SPARQL query comes from my notes in [2017-08]({{< relref "2017-08.md" >}})
