SampleDB API Wrapper

What it does

This package is a simple Python wrapper for the HTTP API of SampleDB, a web-based sample and measurement metadata database developed at PGI and JCNS.

This Python wrapper may also be used e.g. in Matlab and Julia.

Installation

User installation using pip:

pip install --upgrade --user sampledbapi

System installation using pip:

pip install --upgrade sampledbapi

Example usage

Python

from sampledbapi import *

server_address = ...
api_key = ...

# Authentication
authenticate(server_address, api_key)

# Simple queries
print(actions.get_list())
print(objects.get(123))
print(instruments.get_list())

# Advanced search
print(objects.get_list("material == \"Sb\""))

More examples for usage in Python can be found here.

Matlab

You need a working installation of Python and sampledbapi installed for this to work. Some type conversions are needed (e.g. to pass integers).

% Authentication
py.sampledbapi.authenticate("https://...", "your_api_key")

% Simple queries
print(instruments.get_list())
py.sampledbapi.objects.get(py.int(123))
py.sampledbapi.instruments.get_list())

% Advanced search
l = py.sampledbapi.objects.get_list('material == "Sb"')
obj = l{1}
obj.data

In an analogous way, the Python examples shown here can be used in Matlab.

Documentation

The current API documentation can be found here. Further details on the input and output of each function (usually JSON) can be found in the documentation of the HTTP API.
