luxy 0.0.7

A Python wrapper for Yale's Lux API, provided by Yale University.

LuxY is a Python wrapper for Yale's Lux API. Lux allows users to search and filter the collections of Yale's museums and libraries, as well as external collections. This lets you find and connect with the cultural heritage collections across Yale's museums, archives, and libraries in new ways and all in one place.

LuxY gives you a Pythonic way to interact with the Lux API, making it easier to search and filter the collections and even download the data in JSON format. It can handle pagination, nested filters, and more.

Installation

To get started, install LuxY using pip:

pip install luxy

Usage

The classes of LuxY replicate the classes of the Lux API. They are:

1. PeopleGroups (agent) - People and Groups that are either individuals or organizations
2. Objects (item) - Physical objects in Yale's collections
3. Works (work) - Visual and textual works, including images, texts, and other creative expressions
4. Places (place) - Geographic locations and named spaces
5. Concepts (concept) - Types, materials, languages, measurement units, currencies and other conceptual entities
6. Events (event) - Historical events and occurrences
7. Collections (set) - Collections and sets of objects curated by Yale's institutions

Each of these has common and unique filters that take different data types, from strings to numbers to dates. LuxY also supports nested filters, which are used to filter by multiple levels of the hierarchy. This allows users to create complex queries similar to the ones found in the Lux UI.

Understanding Options

Each filter has a set of options that can be used to filter the data. These options are stored in the get_options() method.

from luxy import PeopleGroups

options = PeopleGroups().get_options()
print(options)

# pretty print the options
PeopleGroups().list_filters()

People Groups

from luxy import PeopleGroups

result = PeopleGroups().filter(name="Rembrandt").get()
print(result.url)
print(result.view_url)
print(result.json)

Objects

from luxy import Objects

result = Objects().filter(name="Rembrandt").get()
print(result.url)
print(result.view_url)
print(result.json)

Works

from luxy import Works

result = Works().filter(name="Painting").get()
print(result.url)
print(result.view_url)
print(result.json)

Places

from luxy import Places

result = Places().filter(name="Amsterdam").get()
print(result.url)
print(result.view_url)
print(result.json)

Concepts

from luxy import Concepts

result = Concepts().filter(name="gilding").get()
print(result.url)
print(result.view_url)
print(result.json)

Events

from luxy import Events

result = Events().filter(name="Thirty Years War").get()
print(result.url)
print(result.view_url)
print(result.json)

Collections

from luxy import Collections

result = Collections().filter(name="Letters").get()
print(result.url)
print(result.view_url)
print(result.json)

Working with Numerical Filters

Numerical filters are a bit tricky because they require a tuple with the value and the comparison operator.

from luxy import Objects

result = Objects().filter(height=(1, ">=")).get()
print(result.url)
print(result.view_url)
print(result.json)

Working with Date Filters

Date filters are a bit tricky because they require a tuple with the value and the comparison operator. The value should be a string in the format of YYYY-MM-DDTHH:MM:SS.SSSZ.

from luxy import Objects

result = Objects().filter(encounteredDate=("1987-01-01T00:00:00.000Z", ">=")).get()
print(result.url)
print(result.view_url)
print(result.json)

Complex Example

from luxy import PeopleGroups

result = (
    PeopleGroups()
    .filter(recordType="person")
    .filter(hasDigitalImage=True)
    .filter(text="rembrandt")
    .filter(gender={"name": "male"})
    .get()
)

# print the number of results
print("Number of results:", result.num_results)

# print the url
print("URL:", result.url)

# print the json
print("JSON:", result.json)

Expected Output

Number of results: 131
URL: https://lux.collections.yale.edu/api/search/agent?q=%7B%22AND%22%3A%20%5B%7B%22recordType%22%3A%20%22person%22%7D%2C%20%7B%22hasDigitalImage%22%3A%201%7D%2C%20%7B%22text%22%3A%20%22rembrandt%22%7D%2C%20%7B%22gender%22%3A%20%7B%22id%22%3A%20%22https%3A//lux.collections.yale.edu/data/concept/6f652917-4c07-4d51-8209-fcdd4f285343%22%7D%7D%5D%7D
JSON: {'@context': 'https://linked.art/ns/v1/search.json'...

Working with Pagination

from luxy import PeopleGroups

result = (
    PeopleGroups()
    .filter(endAt={"name": "Amsterdam"})
    .get()
)

# print the number of results
print("Number of results:", result.num_results)
print("Number of pages:", result.num_pages())

for i, page in enumerate(result.get_page_data_all(), 1):
    if i > 2: # Break after 2 pages
        break
    print(f"Page {i}:", page["id"])
    for j, item in enumerate(result.get_items(page)):
        print(f"Item {j}:", result.get_item_data(item)["_label"])

Nested MemberOf Filters

result = (
    Objects()
    .filter(hasDigitalImage=True)
    .filter(
        OR=[
            Objects().memberOf("Letters", depth=2),
            Objects().memberOf("Letters", depth=3),
            Objects().memberOf("Letters", depth=4)
        ]
    )
    .filter(name="letter")
    .get()
)

print(result.url)
print(result.json)
