pycounter

pycounter makes working with COUNTER usage statistics in Python easy, including fetching statistics with NISO SUSHI.

A simple command-line client for fetching JR1 reports from SUSHI servers and outputting them as tab-separated COUNTER 4 reports is included.

Developed by the Health Sciences Library System of the University of Pittsburgh to support importing usage data into our in-house Electronic Resources Management (ERM) system.

pycounter is tested on Python 3.6, 3.7, 3.8, 3.9 and pypy3

Documentation is on Read the Docs and the code can be found on GitHub.

Installing

From pypi:

pip install pycounter

From inside the source distribution:

pip install [-e] .

(use -e if you plan to work on the source itself, so your changes are used in your installation. Probably do all of this in a virtualenv. The PyPA has a good explanation of how to get started.)

COUNTER 5 Note

In this release, reports are output in COUNTER 4 format with COUNTER 5 data, which is wrong, and probably not a valid apples-to-apples comparison since, for example, TR_J1 excludes Gold Open Access counts that would be included in JR1, and also has HTML and PDF columns that will always be 0 because these are no longer reported.

Before the 3.0 release, it should be capable of producing actual COUNTER 5 reports, probably with an API for getting COUNTER 4 style data compatible with scripts that were making assumptions about the data received to pass it into another system.

Usage

Parsing COUNTER reports (currently supports 4 in .csv, .tsv, or .xlsx files, reports JR1, JR2, DB1, DB2, BR1, BR2, and BR3) and COUNTER 5:

>>> import pycounter.report
>>> report = pycounter.report.parse("COUNTER4_2015.tsv")  # filename or path to file
>>> print(report.metric)
FT Article Requests
>>> for journal in report:
...     print(journal.title)
Sqornshellous Swamptalk
Acta Mattressica
>>> for stat in report.pubs[0]:
...     print(stat)
(datetime.date(2015, 1, 1), 'FT Article Requests', 120)
(datetime.date(2015, 2, 1), 'FT Article Requests', 42)
(datetime.date(2015, 3, 1), 'FT Article Requests', 23)

Fetching SUSHI data:

>>> import pycounter.sushi
>>> import datetime
>>> report = pycounter.sushi.get_report(wsdl_url='http://www.example.com/SushiService',
...     start_date=datetime.date(2015,1,1), end_date=datetime.date(2015,1,31),
...     requestor_id="myreqid", customer_reference="refnum", report="JR1",
...     release=4)
>>> for journal in report:
...     print(journal.title)
Sqornshellous Swamptalk
Acta Mattressica

Output of report as TSV:

>>> report.write_tsv("/tmp/counterreport.tsv")
