cn module

cn module API:

  • content_negotiation

Example usage:

from habanero import cn
cn.content_negotiation(ids = '10.1126/science.169.3946.635')
cn.content_negotiation(ids = '10.1126/science.169.3946.635', format = "citeproc-json")
cn.content_negotiation(ids = "10.1126/science.169.3946.635", format = "rdf-xml")
cn.content_negotiation(ids = "10.1126/science.169.3946.635", format = "crossref-xml")
cn.content_negotiation(ids = "10.1126/science.169.3946.635", format = "text")
cn.content_negotiation(ids = "10.1126/science.169.3946.635", format = "bibentry")

cn API

cn.content_negotiation(format='bibtex', style='apa', locale='en-US', url=None, **kwargs)

Get citations in various formats from CrossRef

Supports DOIs from Crossref, Datacite and Medra

Parameters:

  • ids (str) – required. a single DOI or many DOIs, each a string. If many passed in, do so in a list

  • format (str) – Name of the format. One of “rdf-xml”, “turtle”, “citeproc-json”, “citeproc-json-ish”, “text”, “ris”, “bibtex” (Default), “crossref-xml”, “datacite-xml”,”bibentry”, or “crossref-tdm”

  • style (str) – A CSL style (for text format only). See csl_styles() for options. Default: “apa”. If there’s a style that CrossRef doesn’t support you’ll get a (500) Internal Server Error

  • locale (str) – Language locale. See locale.locale_alias

  • url (str) – Base URL for the content negotiation request. Default: https://doi.org

  • kwargs – any additional arguments will be passed on to requests.get

Return type:

str, which can be parsed to various formats depending on what format you request (e.g., JSON vs. XML vs. bibtex)

See https://citation.crosscite.org/docs.html for details

To make for a nicer user experience, when more than one DOI is passed to ids we’ll throw a warning instead of stopping with an error to be able to try to fetch data for all DOIs given. When only one DOI is passed to ids we will fail with error message. A UserWarning is thrown when a DOI is not found or there’s a problem with fetching the citation for a DOI. You can suppress these warnings with warnings.filterwarnings('ignore').

Usage:

from habanero import cn
cn.content_negotiation(ids = "10.1126/science.169.3946.635")

# Using DataCite DOIs
## some formats don't work
# cn.content_negotiation(ids = "10.15468/t4rau8", format = "crossref-xml")

## But most do work
cn.content_negotiation(ids = "10.15468/t4rau8", format = "text")
cn.content_negotiation(ids = "10.15468/t4rau8", format = "crossref-tdm")

cn.content_negotiation(ids = "10.15468/t4rau8", format = "bibtex")

# many DOIs
dois = ['10.5167/UZH-30455','10.5167/UZH-49216','10.5167/UZH-503', '10.5167/UZH-38402','10.5167/UZH-41217']
x = cn.content_negotiation(ids = dois)

# Use a different base url
url = "http://dx.doi.org"
cn.content_negotiation(ids = "10.1126/science.169.3946.635", url = url)
