## 2017-04-02

- Merge one change to CCAFS flagships that I had forgotten to remove last month ("MANAGING CLIMATE RISK"): https://github.com/ilri/DSpace/pull/317
- Quick proof-of-concept hack to add `dc.rights` to the input form, including some inline instructions/hints:

![dc.rights in the submission form](/cgspace-notes/2017/04/dc-rights.png)

- Remove redundant/duplicate text in the DSpace submission license
- Testing the CMYK patch on a collection with 650 items:

```
$ [dspace]/bin/dspace filter-media -f -i 10568/16498 -p "ImageMagick PDF Thumbnail" -v >& /tmp/filter-media-cmyk.txt
```

<!--more-->

## 2017-04-03

- Continue testing the CMYK patch on more communities:

```
$ [dspace]/bin/dspace filter-media -f -i 10568/1 -p "ImageMagick PDF Thumbnail" -v >> /tmp/filter-media-cmyk.txt 2>&1
```

- So far there are almost 500:

```
$ grep -c profile /tmp/filter-media-cmyk.txt
484
```

- Looking at the CG Core document again, I'll send some feedback to Peter and Abenet:
  - We use cg.contributor.crp to indicate the CRP(s) affiliated with the item
  - DSpace has dc.date.available, but this field isn't particularly meaningful other than as an automatic timestamp at the time of item accession (and is identical to dc.date.accessioned)
  - dc.relation exists in CGSpace, but isn't used—rather dc.relation.ispartofseries, which is used ~5,000 times to Series name and number within that series
- Also, I'm noticing some weird outliers in `cg.coverage.region`, need to remember to go correct these later:

```
dspace=# select text_value from metadatavalue where resource_type_id=2 and metadata_field_id=227;
```

## 2017-04-04

- The `filter-media` script has been running on more large communities and now there are many more CMYK PDFs that have been fixed:

```
$ grep -c profile /tmp/filter-media-cmyk.txt
1584
```

- Trying to find a way to get the number of items submitted by a certain user in 2016
- It's not possible in the DSpace search / module interfaces, but might be able to be derived from `dc.description.provenance`, as that field contains the name and email of the submitter/approver, ie:

```
Submitted by Francesca Giampieri (fgiampieri) on 2016-01-19T13:56:43Z^M
No. of bitstreams: 1^M
ILAC_Brief21_PMCA.pdf: 113462 bytes, checksum: 249fef468f401c066a119f5db687add0 (MD5)
```

- This SQL query returns fields that were submitted or approved by giampieri in 2016 and contain a "checksum" (ie, there was a bitstream in the submission):

```
dspace=# select * from metadatavalue where resource_type_id=2 and metadata_field_id=28 and text_value ~ '^(Submitted|Approved).*giampieri.*2016-.*checksum.*';
```

- Then this one does the same, but for fields that don't contain checksums (ie, there was no bitstream in the submission):

```
dspace=# select * from metadatavalue where resource_type_id=2 and metadata_field_id=28 and text_value ~ '^(Submitted|Approved).*giampieri.*2016-.*' and text_value !~ '^(Submitted|Approved).*giampieri.*2016-.*checksum.*';
```

- For some reason there seem to be way too many fields, for example there are 498 + 13 here, which is 511 items for just this one user.
- It looks like there can be a scenario where the user submitted AND approved it, so some records might be doubled...
- In that case it might just be better to see how many the user submitted (both _with_ and _without_ bitstreams):

```
dspace=# select * from metadatavalue where resource_type_id=2 and metadata_field_id=28 and text_value ~ '^Submitted.*giampieri.*2016-.*';
```

## 2017-04-05

- After doing a few more large communities it seems this is the final count of CMYK PDFs:

```
$ grep -c profile /tmp/filter-media-cmyk.txt
2505
```

## 2017-04-06

- After reading the [notes for DCAT April 2017](https://wiki.duraspace.org/display/cmtygp/DCAT+Meeting+April+2017) I am testing some new settings for PostgreSQL on DSpace Test:
  - `db.maxconnections` 30→70 (the default PostgreSQL config allows 100 connections, so DSpace's default of 30 is quite low)
  - `db.maxwait` 5000→10000
  - `db.maxidle` 8→20 (DSpace default is -1, unlimited, but we had set it to 8 earlier)
- I need to look at the Munin graphs after a few days to see if the load has changed
- Run system updates on DSpace Test and reboot the server
- Discussing harvesting CIFOR's DSpace via OAI
- Sisay added their OAI as a source to a new collection, but using the Simple Dublin Core method, so many fields are unqualified and duplicated
- Looking at the [documentation](https://wiki.duraspace.org/display/DSDOC5x/XMLUI+Configuration+and+Customization) it seems that we probably want to be using DSpace Intermediate Metadata

## 2017-04-10

- Adjust Linode CPU usage alerts on DSpace servers
  - CGSpace from 200 to 250%
  - DSpace Test from 100 to 150%
- Remove James from Linode access
- Look into having CIFOR use a sub prefix of 10568 like 10568.01
- Handle.net calls this ["derived prefixes"](https://www.handle.net/faq.html#4) and it seems this would work with DSpace if we wanted to go that route
