Low Level Client for Crossref Search API

habanero

This is a low level client for working with Crossref’s search API. It’s been named to be more generic, as other organizations are/will adopt Crossref’s search API, making it possible to interact with all from one client.

Crossref API docs

Other Crossref API clients:

• Ruby: serrano, https://github.com/sckott/serrano

• R: rcrossref, https://github.com/ropensci/rcrossref

habanero includes three modules you can import as needed (or import all):

Crossref - Crossref search API. The Crossref module includes methods matching Crossref API routes, and a few convenience methods for getting DOI agency and random DOIs:

• works - /works route

• members - /members route

• prefixes - /prefixes route

• funders - /funders route

• journals - /journals route

• types - /types route

• licenses - /licenses route

• registration_agency - get DOI minting agency

• random_dois - get random set of DOIs

counts - citation counts. Includes the single citation_count method

cn - content negotiation. Includes the methods:

• content_negotiation - get citations in a variety of formats

• csl_styles - get CSL styles, used in content_negotation method

Note about searching:

You are using the Crossref search API described at https://github.com/CrossRef/rest-api-doc/blob/master/rest_api.md. When you search with query terms, on Crossref servers they are not searching full text, or even abstracts of articles, but only what is available in the data that is returned to you. That is, they search article titles, authors, etc. For some discussion on this, see https://github.com/CrossRef/rest-api-doc/issues/101

Rate limits

See the headers X-Rate-Limit-Limit and X-Rate-Limit-Interval for current rate limits.

Installation

Stable version

pip install habanero

Dev version

sudo pip install git+git://github.com/sckott/habanero.git#egg=habanero

# OR

git clone [e-mail]:sckott/habanero.git
cd habanero
make install

Usage

Initialize a client

from habanero import Crossref
cr = Crossref()

Works route

x = cr.works(query = "ecology")
x['message']
x['message']['total-results']
x['message']['items']

Members route

cr.members(ids = 98, works = True)

Citation counts

from habanero import counts
counts.citation_count(doi = "10.1016/j.fbr.2012.01.001")

Content negotiation - get citations in many formats

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 = "text")
cn.content_negotiation(ids = "10.1126/science.169.3946.635", format = "text", style = "apa")
cn.content_negotiation(ids = "10.1126/science.169.3946.635", format = "bibentry")

Changelog

0.3.0 (2017-05-21)

• Added more documentation for field queries, describing available fields that support field queries, and how to do field queries (#50)

• sample parameter maximum value is 100 - has been for a while, but wasn’t updated in Crossref docs (#44)

• Updated docs that facet parameter can be a string query in addition to a boolean (#49)

• Documented new 10,000 max value for /works requests - that is, for the offset parameter - if you need more results than that use cursor (see https://github.com/CrossRef/rest-api-doc/blob/master/rest_api.md#deep-paging-with-cursors) (#47)

• Added to docs a bit about rate limiting, their current values, that they can change, and how to show them in verbose curl responses (#45)

• Now using https://doi.org for cn.content_negotation - and function gains new parameter url to specify different base URLs for content negotiation (#36)

• Fixes to kwargs and fix docs for what can be passed to kwargs (#41)

• Duplicated names passed to filter were not working - fixed now (#48)

• Raise proper HTTP errors when appropriate for cn.content_negotiation thanks @jmaupetit (#55)

0.2.6 (2016-06-24)

• fixed problem with cr.works() where DOIs passed weren’t making the correct API request to Crossref (#40)

• added support for field queries to all methods that support /works (<https://github.com/CrossRef/rest-api-doc/blob/master/rest_api.md#field-queries>) (#38)

0.2.2 (2016-03-09)

• fixed some example code that included non-working examples (#34)

• fixed bug in registration_agency() method, works now! (#35)

• removed redundant filter_names and filter_details bits in docs

0.2.0 (2016-02-10)

• user-agent strings now passed in every http request to Crossref, including a X-USER-AGENT header in case the User-Agent string is lost (#33)

• added a disclaimer to docs about what is actually searched when searching the Crossref API - that is, only what is returned in the API, so no full text or abstracts are searched (#32)

• improved http error parsing - now passes on the hopefully meaningful error messages from the Crossref API (#31)

• more tests added (#30)

• habanero now supports cursor for deep paging. note that cursor only works with requests to the /works route (#18)
