This library provides a Python client to interact with the DigitalNZ API version 3. It supports searching records and getting metadata for a specific record, returning all results as Python dictionaries loaded from the returned JSON.
from dnz_client import get_client
client = get_client("my API token") # Omit token for anonymous use
_and = {"collection": "Music 101", "subject": "Cats", "Weddings"}
_or = {"category": ["Books", "Articles"]}
results = client.search(
text="Wanganui OR Whanganui", _and=_and, _or=_or,
geo_bbox=["-41", "174", "-42", "175"], "direction": "asc")
metadata = client.metadata(record_id=6330666, fields=["id", "title"])The keyword arguments passed to the search method are those specified in the API documentation.
The arguments _and, _or, and _without contain dictionaries keyed to the fields that are so joined; each value may be a string or list of strings.
The keyword arguments facets, fields, and geo_bbox each take a list of strings.
The other fields (direction, exclude_filters_from_facets, facets_page, page, per_page, sort, and text) are either string or integer values, as appropriate.
The return values of both search() and metadata() are dictionaries loaded from the JSON returned by DigitalNZ.
OR filters combined across multiple fields are not supported. For example, it is supported to search for records where the category is either "Audio" or "Videos", but searching for those records where the category is either "Audio" or "Videos" and the year is either "2014" or "2015" is not.
The client does no checking that supplied values are sensible or permitted by the DigitalNZ API. For example, any string may be passed as the direction field, though the API permits only "asc" and "desc".
See the underlying api-client documentation for the exceptions the client raises.
