[dspace-tech] External RSS as if it was a submission process in Dspace?

[Hugo Carlos]

Hello!
Is it possible to use an RSS feed (a custom scopus feed that notifies me of 
new indexed publications from my institution for example), to automatically 
create the records of that RSS in Dpsace records? As if the RSS feed inject 
itens as a submission process? So would the operator could just check the 
items before they are made public? 
I do not have knowledge about RSS. Just a thought.

Regards

[dspace-tech] Re: DSpace 6.2 with collection home page too slow to load if items have lots of bitsteams

[Hugo Carlos]

Hi,

I think we had similar issues with xmlui at the exhibition of some itens we 
imported from scopus, where there are a large group of author (2000 people 
at the CERN workgroup, for example,as you can see from the attached image). 
We had modified the item-view.xml to look only for 3 of the author. (as 
seen in second image with the same registry), and it apparently solved the 
issue of performance when to exhibit those itens. Maybe if you limit the 
bitstreams to look when xml is building the exhibition could solve your 
issue?

[dspace-tech] Icon next to authorities names

[Hugo Carlos]

Hello! Guys, I have seen that some repositories have an icon of the 
researcher's institution next to their name in the DSpace.

How to achieve this? I saw several repositories have this interesting 
visual resource that facilitates identification of which author belongs to 
the institution, according to the example below. However, unfortunately I 
do not even know the name of this feature to search google correctly. Could 
anyone help?

Example:



























== in portuguese: 

Olá! Pessoal, tenho visto que alguns repositórios possuem um ícone da 
instituição do pesquisador ao lado do seu nome no Dspace.

Como conseguir isso? Vi vários repositórios terem esse interessante recurso 
visual que facilita identificação de qual o autor pertencente a 
instituição, conforme exemplo abaixo. Porem, infelizmente não sei nem ao 
menos o nome desse recurso para buscar no google corretamente. Alguém 
poderia ajudar?

Hi, writing to update progress


My problem was solved when I quit from use the JSPUI tool for importing 
metadata and used the command line for doing so. It worked very well

[Hugo Carlos]

Hi, I am having the same trouble here. If I change the Key for journal 
title, or article title it works fine. But if I add keys to the mapping, 
everything crashes. It is frustrating because I follow all the instructions 
with no results.
