[Okular-devel] References tab on Okular

[Mailson Lira]

Hello everyone,

During the Akademy I talked to a user (Ran Lu, if I typed his name
correctly) who did a cool modification (see attached snapshot) on Okular,
so I thought it would be good sharing this with you.

This modification is really useful to quickly look for the references of an
article. If you ever read an article and needed to go the the references
page every now and then, you'll probably enjoy this.
Of course all of this is a hack and only works for a particular scenario
but since ideas are always welcome I couldn't keep this to myself. What if
someone on this mailing list come up with a definitive solution for that?
Who knows?

I'm quoting the original author:

The basic idea is to get meta information of the certain pdf file and show
> them
> in okular. I works on high energy physics, and everyone upload their paper
> to
> arxiv.org. For most of the high energy papers, there is another website
> inspirehep.net contains all the metadata of those paper(it is not 100%
> accurate, for papers uploaded to arXiv in the current week it is more like
> 20%, but that is the best they can do).
> Now you have the background. What I did with okular is when it opens a file
> directly from arXiv, the file name is the unique id(not really before 2000,
> when they have prefix like "hep-ph" or "hep-th" in front of the number id)
> of
> the papers. I use this id to search inspirehep for the meta data of this
> paper, mostly references and citations, and if the refered or cited paper
> is
> also on arXiv, download and show it when people click on the item.
> Inspirehep
> is like the facebook for high energy physicists, citing others is like be

> Implementation wise as I said it is a hack, I use two python scripts I

> panel. I put the scripts and the code for reference panel, there are
> several

> panel,
> but the general idea is the same.
> And finally here is the snapshots, and the scripts and patches. You can see
> from the snapshot the result is far from perfect, but I do not know any
> way to

> any
> possible way.
