Displaying related works in DataCite Search

[julian...@g.harvard.edu]

Hi everyone,

I remember that when looking at a work in DataCite Search, the page displayed related works that were in the relatedidentifiers property and had DOIs. For example, looking at this dataset, its files would be displayed on the page below it. I thought this was because in the dataset's DataCite metadata, the files, which also had DOIs, were listed with HasPart relationTypes:

<relatedIdentifiers>
    <relatedIdentifier relatedIdentifierType="DOI" relationType="HasPart">10.5061/DRYAD.54H75R8/1</relatedIdentifier>

So the page used to look something like this (there might've been some heading to show the hierarchy, that the file was part of the dataset):

But now it displays only the work. The same would've been done for files: the page made it obvious which other work it was a part of. 

Is it correct that DataCite Search used to use the relatedIdentifier metadata to display related works this way? This was a nice feature, so I'm wondering if there plans to bring it back or do something similar. Was it removed because of issues with displaying large numbers of related works or handling different relationTypes?

Cheers,

Julian Gautier

Hi again,

Looks like the UI's changed, at least for works that list other works with certain relationTypes. :)

Looks like files don't list their datasets, yet. Anyway, this is a very cool change.

Cheers,

Julian

Julian,

we don't show this information anymore as it very much slowed down our system in some cases with lots of related identifiers. We are in the process of relaunching this using the Event Data service. An example API call would be https://api.datacite.org/events?doi=10.5061/dryad.p85q4.1, but we haven't loaded all relatedIdentifier data yet (that should be done by the end of the month).

Best,

Martin
