The database takes a big hit for OAI-PMH requests that include hyper-authored papers.

We have a block of 100 records that contains ~10 ATLAS research papers - each with 3,000+ authors.

This takes a while to generate the XML response (there's *a lot* of nodes that get created).

 

I've got this EPScript addition to limit the authors in a citation (it's not perfect - I should have used a couple of phrases in there - if I was going to share it formally).

https://gist.github.com/jesusbagpuss/fbec13d9986fba8e93b56ae5ba34c164

 

On our summary page we also have the full author list displayed.

For us, the issue we're concerned about is that when we have a paper with loads of authors, if someone editing the item visits a workflow stage with the authors on it, it takes *ages* to do anything.

 

Our repo staff want to retain the complete author list - so I'll continue looking down the 'improved input methods' path rather than 'truncate from source' option.

 

Cheers,

John

 

 

Hi,

we thought of limiting the rendering, too. However, in that case, the database has to deliver the author records before the limit is applied, which involves a performance penalty. Anyone who had to deal with a 2000 author item in EPrints can tell what this is like. That's why we decided to limit on input already.  

Cheers,

Martin

Hi Martin,
Interesting approach. The records I'm, looking at all come via Symplectic or Pure - and we could implement some form of limit to the number of authors - and retain any that are 'resolved' (local) authors.
 
I was thinking of changing the default input rendering for the creator field along these lines:
If there are < LIMIT authors, render input as currently exists
If there are > LIMIT authors, render a static list of them, and enhance with _javascript_ to allow editing of specific entries / re-ordering / searching filtering the list.
 
This could even be deployed as a separate workflow stage (which only appears when there are > LIMIT authors).
 
I'll have to see what people here think about limiting the author list on the way in to EPrints - that sounds like a better place to be…
 
Cheers,
John

Hi John,

we have a lot of high energy physics or biomedical articles with hundreds or thousands of authors. Usually, those are submitted via CrossRef or PubMed import.

We have adapted the corresponding import plugins to limit the number of authors by a configurable limit (in our case 30). If the limit is exceeded, "et al" is added as the  ($limit+1)th author, the remaining authors are not imported and a warning message is issued. Submitters are then still free to add the remaining UZH authors manually and use et al for authors outside of UZH.

Instead of the DOI plugin, we have developed a CrossRef plugin that uses the CrossRef REST API . It implements the author limitation as well. We decided to go with the CrossRef REST API because funder information can be imported from there.

Best regards,

Martin

Hi,
Has anyone done any work on making the EPrints workflow a bit more sensible when a paper has many authors (hundreds or thousands)?

Cheers,
John
