65. Look for published version in arXiv
|
||||
70. No DOI for HAL => metadata with SOAP API… don't want to handle it for now :/
|

80. Search engine
|

100. UTF-8 ?
|
||||
200. Webserver interface ? GUI ? (not likely for now…)
|

Keep multiple versions of papers
|

Check stored versions when updating arxiv papers
|

Export of bibtex
|

Tree à la docear ?
|

## Issues ?
|

|

* Multiplication of {{}} => solved in bibtexparser
|

* UTF-8 and bibtexparser => solved upstream in bibtexparser

===> TODO : update bibtexparser when available in pip

## Thanks
