Base Methods

The base methods could be used along with the query, filter, sort, order and facet methods.

Version

This method returns the Crossref API version.

In [1]: from crossref.restful import Journals

In [2]: journals = Journals()

In [3]: journals.version
Out[3]: '1.0.0'

Count

This method returns the total number of items a query result should retrieve. This method will not iterate through and retrieve the API documents. This method will fetch 0 documents and retrieve the value of total-result attribute.

In [1]: from crossref.restful import Works

In [2]: works = Works()

In [3]: works.query('zika').count()
Out[3]: 3597

In [4]: works.query('zika').filter(from_online_pub_date='2017').count()
Out[4]: 444

Url

This method returns the url that will be used to query the Crossref API.

In [1]: from crossref.restful import Works

In [2]: works = Works()

In [3]: works.query('zika').url
Out[3]: 'https://api.crossref.org/works?query=zika'

In [4]: works.query('zika').filter(from_online_pub_date='2017').url

All

This method returns all items of an endpoint. It will use the limit offset parameters to iterate through the endpoints Journals, Types, Members and Prefixes.

For the works endpoint, the library will make use of the cursor to paginate through API until it is totally consumed.

In [1]: from crossref.restful import Journals

In [2]: journals = Journals()

In [3]: for item in journals.all():
   ...:     print(item['title'])
   ...:
JNSM
New Comprehensive Biochemistry
New Frontiers in Ophthalmology
Oral Health Case Reports
Orbit A Journal of American Literature
ORDO

Support for Polite Requests (Etiquette)

Respecting the Crossref API polices for polite requests. This library allows users to setup an Etiquette object to be used in the http requests.

In [1]: from crossref.restful import Works, Etiquette

In [2]: my_etiquette = Etiquette('My Project Name', 'My Project version', 'My Project URL', 'My contact email')

In [3]: str(my_etiquette)
Out[3]: 'My Project Name/My Project version (My Project URL; mailto:My contact email) BasedOn: CrossrefAPI/1.1.0'

In [4]: my_etiquette = Etiquette('My Project Name', '0.2alpha', 'https://myalphaproject.com', '[email protected]')

In [5]: str(my_etiquette)
Out[5]: 'My Project Name/0.2alpha (https://myalphaproject.com; mailto:[email protected]) BasedOn: CrossrefAPI/1.1.0'

In [6]: works = Works(etiquette=my_etiquette)

In [7]: for i in works.sample(5).select('DOI'):
   ...:     print(i)
   ...:

{'DOI': '10.1016/j.ceramint.2014.10.086'}
{'DOI': '10.1016/j.biomaterials.2012.02.034'}
{'DOI': '10.1001/jamaoto.2013.6450'}
{'DOI': '10.1016/s0021-9290(17)30138-0'}
{'DOI': '10.1109/ancs.2011.11'}

Voilá!!! The requests made for the Crossref API, were made setting the user-agent as: 'My Project Name/0.2alpha (https://myalphaproject.com; mailto:[email protected]) BasedOn: CrossrefAPI/1.1.0'

Depositing Metadata to Crossref

This library implements the deposit operation "doMDUpload", it means you are able to submit Digital Objects Metadata to Crossref. Se more are: https://support.crossref.org/hc/en-us/articles/214960123

To do that, you must have an active publisher account with crossref.org.

First of all, you need a valid XML following the crossref DTD.

Explaining the code

Line 1: Importing the Depositor Class

Line 2: Loading a valid XML for deposit

Line 3: Creating an instance of Depositor. You should use you crossref credentials at this point. If you wana be polite, you should also give an etiquette object at this momment.

.. block-code:: python

  etiquette = Etiquette('My Project Name', 'My Project version', 'My Project URL', 'My contact email')
  Depositor('your prefix', 'your crossref user', 'your crossref password', etiquette)

Line 4: Requesting the DOI (Id do not means you DOI was registered, it is just a DOI Request)

Line 5: Checking the DOI request response.

Line 6: Printing the DOI request response body.

Line 7: Requesting the DOI registering status.

Line 8: Checking the DOI registering status, reading the body of the response. You should parse this XML to have the current status of the DOI registering request. You should do this util have an success or error status retrieved.

Line 9-12: Rechecking the request status. It is still in queue. You can also set the response type between ['result', 'contents'], where result will retrieve the status of the DOI registering process, and contents will retrieve the submitted XML content while requesting the DOI.

Line 13-14: Checking the content submitted passing the attribute data_type='contents'.

Line 15-16: After a while, the success status was received.
