OSCN package

oscn

• counties: Returns a list of counties.
• courts: Same as counties but more a accurate description.
• judges: Returns a list of objects formated as {'name': 'Bond, James', 'number': '007'}
• types: returns a dict of case type codes and descriptons
• type: function to return case type description. Usage:

  >>> oscn.type("AO")
  'CIVIL ADMINISTRATIVE'
  

oscn.request

• Case: Returns a single case. Case can be saved as files using Case.save() and retrieved using Case.open().

• CaseList: Returns an iterator for retrieving cases for a county and year. CaseLists can be filtered using .find(). See scripts/example.py for details

• Party: Returns information on parties available on OSCN.

• Docket: Returns docket of cases for specific judges and date

oscn.parse

Parsers accept the html of an OSCN page and return python objects.

Case Page Parsers

• filed: returns a string of the filing date (e.g. 12/25/2017)
• closed: returns a string of the date the case was closed. Return None if not closed.
• counts: returns of list of count dicts found in a case. Keys include 'description' of the count. If available 'violation' and 'disposed' are added.
• judge: returns a string of the judge's name
• parties: returns a list of dicts with these keys: id, name, type
• docket: returns a list of rows in a docket
• events: returns a list of dicts with these keys: event, party, docket, reporter, date, description. The keys date and description are cleaner versions of the event text. The event key will be deprecated some day so use date and description if you are starting a project.
• attorneys: returns a list of dicts with these keys: name, address, and representing
• issues: returns a list of dicts with issue information. Each issues includes a list of dicts for each party

Party Page Parsers

• name: returns 'Requested Party'
• alias: returns 'Alias or Alternate Names'
• profile: returns dict of values in 'Personal Profile'
• birth_month: returns string of 'Birth Month and Year'
• addresses: returns a list of dicts for each address

Docket Page Parsers

• cases: returns a list of case indexes
• tables: returns the html table for each case in the docket

oscn.find

• CaseIndexes: returns an iterator of case indexes (e.g. tulsa-CF-2019-12).

Usage

Create a CaseIndexes list using these key word arguments:

• county: defaults to all,
• last_name: use this for company or organization names
• first_name: optional
• middle_name: optional
• filed_after: More readable than FiledDateL
• filed_before: More readable than FiledDateH
• closed_after: More readable than ClosedDateL
• closed_before: More readable than ClosedDateH

Notes

• The % wild card is added to all words in name, first and middle
• Date arguments use MM/DD/YYY strings.

OSCN search parameters

If you are familar with the OSCN search parameters you can initialize CaseIndexes using these as key word arguments: db, number, lname, fname, mname, DoBMin, DoBMax, partytype, apct, dcct, FiledDate, FiledDateH, ClosedDateL, ClosedDateH, iLC, iLCType, iYear, iNumber, and citation

Using this will override init keyword values such as first or filed_after.

Development Install

1. Create and activate a Python 3.6 virtual env
2. git clone [e-mail]:codefortulsa/oscn.git
3. cd oscn
4. pip install -e .

Usage

Install with pip install oscn

Script example:

import oscn

Request a single case:

oscn.request.Case(county='tulsa', year='2018', number=84)

or use case index notation:

oscn.request.Case('love-CF-2019-25')

To request a list of cases to iterate:

oscn.request.CaseList(county='adair', year='2016')

Run test scripts

• pytest tests/

or with ipdb:

- `pytest -s tests/`

specify a test:

• pytest -s tests/test_parse.py -k 'test_events'

Deployment steps

1. Edit setup.py
2. python3 setup.py sdist bdist_wheel
3. twine upload dist/*

User Agent

In some cases a custom user agent is required in the header of requests. Setting an environmental varialbe called OSCN_USER_AGENT will override the default.
