EP Register Support

[parkerhancock]

This issue is tracking the work to implement the EP Register endpoints on patent_client. At least for the moment, @xi2pi has volunteered to make a run at this.

The endpoints we'd want to include are:

• Register Search w/o Constituents - register/search
• Register Retrieval Service - register/{type}/{format}/{number}/biblio
• Register Events Service - register/{type}/{format}/{number}/events
• Register Procedural Steps - /register/{type}/{format}/{number}/procedural-steps

These can be played around with at (https://developers.epo.org/ops-v3-2/apis). They are also documented in the EPO OPS documentation at pages 103-112.

A (broken) example of use is in the documentation:

>>> from patent_client import Epo 
>>> pub = Epo.objects.get("EP3221665A1") 
>>> pub.status[0] 
{'description': 'Request for examination was made', 'code': '15', 'date': '20170825'}
>>> pub.title 
'INERTIAL CAROUSEL POSITIONING'
>>> pub.procedural_steps[0] 
http://ops.epo.org/3.2/rest-services/register/publication/epodoc/EP.3221665.A1/procedural-steps {}
{'phase': 'undefined', 'description': 'Renewal fee payment - 03', 'date': '20171113', 'code': 'RFEE'}

This issue will track notes and thoughts on implementation details. For starters, let's do the EPO Search, which should look a lot like the Inpadoc search as an example, which is implemented in 4 files:

• API Wrapper - src/patent_client/epo/ops/published/api.py
• Manager - src/patent_client/epo/ops/published/manager.py
• Model - src/patent_client/epo/ops/published/model/search.py
• Schema - src/patent_client/epo/ops/published/schema/search.py

I would suggest this order for development:

1. Write an API Wrapper at src/patent_client/epo/ops/register/api.py that just returns raw XML data. Don't worry about processing it, just get it to return the right XML data from the EPO endpoint. Use the PublishedSearchAPI in the published/api.py file as an example.

2. Write a Schema at src/patent_client/epo/ops/register/schema.py that converts the raw XML data into a Python dictionary with the data attributes you want. Use the SearchSchema class and InpadocSchema classes in published/schema/search.py as examples.

3. Write a Model at src/patent_client/epo/ops/register/model.py to hold the data the Schema produced. Use the Search and Inpadoc classes in published/model/search.py as examples.

4. Write a Manager at src/patent_client/epo/ops/register/manager.py that will serve as the manager for the EP Register resource. use the SearchManager class in published/manager.py as an example.

And please let me know if you have any questions or concerns!

I followed your instruction and created a first prototype.

There is an example case in src/patent_client/epo/ops/register/example_ep_register.py
