- Skype with Michael and Peter, discussing moving the CGIAR Library to CGSpace
- CGIAR people possibly open to moving content, redirecting library.cgiar.org to CGSpace and letting CGSpace resolve their handles
- They might come in at the top level in one "CGIAR System" community, or with several communities
- I need to spend a bit of time looking at the multiple handle support in DSpace and see if new content can be minted in both handles, or just one?
- Need to send Peter and Michael some notes about this in a few days
- Also, need to consider talking to Atmire about hiring them to bring ORCiD metadata to REST / OAI

- Filed an issue on DSpace issue tracker for the `filter-media` bug that causes it to process JPGs even when limiting to the PDF thumbnail plugin: [DS-3516](https://jira.duraspace.org/browse/DS-3516)
- Discovered that the ImageMagic `filter-media` plugin creates JPG thumbnails with the CMYK colorspace when the source PDF is using CMYK
- Interestingly, it seems DSpace 4.x's thumbnails were sRGB, but forcing regeneration using DSpace 5.x's ImageMagick plugin creates CMYK JPGs if the source PDF was CMYK (see [10568/51999](https://cgspace.cgiar.org/handle/10568/51999)):
```

- This results in discolored thumbnails when compared to the original PDF, for example sRGB and CMYK:

## 2017-03-03
- I created a patch for DS-3517 and made a pull request against upstream `dspace-5_x`: https://github.com/DSpace/DSpace/pull/1669
- Looks like `-colorspace sRGB` alone isn't enough, we need to use profiles:

- This reads the input file, applies the CMYK profile, applies the RGB profile, then writes the file
- Note that you should set the first profile immediately after the input file
- Also, it is better to use profiles than setting `-colorspace`

- This is a great resource describing the color stuff: http://www.imagemagick.org/Usage/formats/#profiles
Update notes for 2017-03-03
2017-03-04 00:15:47 +01:00
- Somehow we need to detect the color system being used by the input file and handle each case differently (with profiles)

- This is trivial with `identify` (even by the [Java ImageMagick API](http://im4java.sourceforge.net/api/org/im4java/core/IMOps.html#identify)):
```
$ identify -format '%r\n' alc_contrastes_desafios.pdf\[0\]
DirectClass CMYK
$ identify -format '%r\n' Africa\ group\ of\ negotiators.pdf\[0\]
DirectClass sRGB Alpha
```

## 2017-03-04
- Spent more time looking at the ImageMagick CMYK issue
- The `default_cmyk.icc` and `default_rgb.icc` files are both part of the Ghostscript GPL distribution, but according to DSpace's `LICENSES_THIRD_PARTY` file, DSpace doesn't allow distribution of dependencies that are licensed solely under the GPL
- So this issue is kinda pointless now, as the ICC profiles are absolutely necessary to make a meaningful CMYK→sRGB conversion

## 2017-03-05
- Look into helping developers from landportal.info with a query for items related to LAND on the REST API
- They want something like the items that are returned by the general "LAND" query in the search interface, but we cannot do that
- We can only return specific results for metadata fields, like:
```
$ curl -s -H "accept: application/json" -H "Content-Type: application/json" -X POST "https://dspacetest.cgiar.org/rest/items/find-by-metadata-field" -d '{"key": "cg.subject.ilri","value": "LAND REFORM", "language": null}' | json_pp
```
- But there are hundreds of combinations of fields and values (like `dc.subject` and all the center subjects), and we can't use wildcards in REST!

- Reading about enabling multiple handle prefixes in DSpace
- There is a mailing list thread from 2011 about it: http://dspace.2283337.n4.nabble.com/Multiple-handle-prefixes-merged-DSpace-instances-td3427192.html
- And a comment from Atmire's Bram about it on the DSpace wiki: https://wiki.duraspace.org/display/DSDOC5x/Installing+DSpace?focusedCommentId=78163296#comment-78163296
- Bram mentions an undocumented configuration option `handle.plugin.checknameauthority`, but I noticed another one in `dspace.cfg`:
```
# List any additional prefixes that need to be managed by this handle server
# (as for examle handle prefix coming from old dspace repository merged in
# that repository)
# handle.additional.prefixes = prefix1[, prefix2]
```
- Because of this I noticed that our Handle server's `config.dct` was potentially misconfigured!
- We had some default values still present:
```
"300:0.NA/YOUR_NAMING_AUTHORITY"
```
- I've changed them to the following and restarted the handle server:
```
"300:0.NA/10568"
```
- In looking at all the configs I just noticed that we are not providing a DOI in the Google-specific metadata crosswalk
- From `dspace/config/crosswalks/google-metadata.properties`:
```
google.citation_doi = cg.identifier.doi
```
- This works, and makes DSpace output the following metadata on the item view page:
```
<meta content="https://dx.doi.org/10.1186/s13059-017-1153-y" name="citation_doi">
```
- Submitted and merged pull request for this: https://github.com/ilri/DSpace/pull/305

- Someone on the mailing list said that `handle.plugin.checknameauthority` should be false if we're using multiple handle prefixes

## 2017-03-07
- I set up a top-level community as a test for the CGIAR Library and imported one item with the the 10947 handle prefix
- When testing the Handle resolver locally it shows the item to be on the local repository
- So this seems to work, with the following caveats:
- New items will have the default handle
- Communities and collections will have the default handle
- Only items imported manually can have the other handles

- I need to talk to Michael and Peter to share the news, and discuss the structure of their community(s) and try some actual test data
- We'll need to do some data cleaning to make sure they are using the same fields we are, like `dc.type` and `cg.identifier.status`
Update notes for 2017-03-07
2017-03-07 17:05:24 +01:00
- Another thing is that the import process creates new `dc.date.accessioned` and `dc.date.available` fields, so we end up with duplicates (is it important to preserve the originals for these?)

- Report DS-3520 issue to Atmire
## 2017-03-08
- Merge the author separator changes to `5_x-prod`, as everyone has responded positively about it, and it's the default in Mirage2 afterall!
- Cherry pick the `commons-collections` patch from DSpace's `dspace-5_x` branch to address DS-3520: https://jira.duraspace.org/browse/DS-3520

- Export list of sponsors so Peter can clean it up:
```
dspace=# \copy (select text_value, count(*) from metadatavalue where resource_type_id=2 and metadata_field_id IN (select metadata_field_id from metadatafieldregistry where element = 'description' and qualifier = 'sponsorship') group by text_value order by count desc) to /tmp/sponsorship.csv with csv;
COPY 285
