- Update PostgreSQL JDBC driver to 42.3.5 in the Ansible infrastructure playbooks and deploy on DSpace Test
- Peter asked me how many items we add to CGSpace every year
- I wrote a SQL query to check the number of items grouped by their accession dates since 2009:
```console
localhost/dspacetest= ☘ SELECT EXTRACT(year from text_value::date) AS YYYY, COUNT(*) FROM metadatavalue WHERE metadata_field_id=11 GROUP BY YYYY ORDER BY YYYY DESC LIMIT 14;
yyyy │ count
──────┼───────
2022 │ 2073
2021 │ 6471
2020 │ 4074
2019 │ 7330
2018 │ 8899
2017 │ 6860
2016 │ 8451
2015 │ 15692
2014 │ 16479
2013 │ 4388
2012 │ 6472
2011 │ 2694
2010 │ 2457
2009 │ 293
```
- Note that I had an issue with casting `text_value` to date because one item had an accession date of `2016` instead of `2016-09-29T20:14:47Z`
- Once I fixed that PostgreSQL was able to [extract() the year](https://www.postgresql.org/docs/12/functions-datetime.html#FUNCTIONS-DATETIME-EXTRACT)
- There were some other methods I tried that worked also, for example `TO_DATE()`:
```console
localhost/dspacetest= ☘ SELECT EXTRACT(year from TO_DATE(text_value, 'YYYY-MM-DD"T"HH24:MI:SS"Z"')) AS YYYY, COUNT(*) FROM metadatavalue WHERE metadata_field_id=11 GROUP BY YYYY ORDER BY YYYY DESC LIMIT 14;
```
- But it seems PostgreSQL is smart enough to recognize date formatting in strings automatically when we cast so we don't need to convert to date first
- Another thing I noticed is that a few hundred items have accession dates from decades ago, perhaps this is due to importing items from the CGIAR Library?
- I also submitted a [pull request to migrate Mirage 2's build from bower and compass to yarn and node-sass](https://github.com/DSpace/DSpace/pull/8288)
- Submit an issue to Atmire's bug tracker inquiring about DSpace 6.4 support
## 2022-05-10
- Submit an updated [pull request to migrate Mirage 2's build from bower and compass to npm and node-sass](https://github.com/DSpace/DSpace/pull/8292)
- This one is better than the previous one because it uses npm directly, which comes with the Node.js distribution, rather than requiring the user to install yarn
