Top-level package for xedocs.

Project description

xedocs is meant to replace cmt and bodega as well as helping tracking all shared documents especially if they need to be versioned.

What does Xedocs give you

Data reading

  • Read data from multiple formats (e.g. mongodb, pandas) and locations with a simple unified interface.

  • Custom logic implemented on the document class, e.g. creating a tensorflow model from the data etc.

  • Multiple APIs for reading data, fun functional, ODM style, pandas and xarray.

  • Read data as objects, dataframes, dicts, json.

Writing data

  • Write data to multiple storage backends with the same interface

  • Custom per-collection rules for data insertion, deletion and updating.

  • Schema validation and type coercion so storage has uniform and consistent data.


  • Custom panel widgets for graphical representation of data, web client

  • Auto-generated API server and client + openapi documentation

  • CLI for viewing and downloading data

Basic Usage

Explore the available schemas

import xedocs

>>> xedocs.list_schemas()
>>> ['detector_numbers',


        Schema name: pmt_area_to_pes
        Index fields: ['version', 'time', 'detector', 'pmt']
        Column fields: ['created_date', 'comments', 'value']

Read/write data from the shared development database, this database is writable from the default analysis username/password

import xedocs

db = xedocs.development_db()

docs = db.pmt_area_to_pes.find_docs(version='v1', pmt=[1,2,3,5], time='2021-01-01T00:00:00', detector='tpc')
to_pes = [doc.value for doc in docs]

# passing a run_id will attempt to fetch the center time of that run from the runs db
doc = db.pmt_area_to_pes.find_one(version='v1', pmt=1, run_id=25000, detector='tpc')
to_pe = doc.value

Read from the straxen processing database, this database is read-only for the default analysis username/password

import xedocs

db = xedocs.straxen_db()


Read from the the corrections gitub repository, this database is read-only

import xedocs

db = xedocs.corrections_repo(branch="master")


If you cloned the corrections gitub repo to a local folder, this database can be read too

import xedocs

db = xedocs.local_folder(PATH_TO_REPO_FOLDER)


Read data from alternative data sources specified by path, e.g csv files which will be loaded by pandas.

from xedocs.schemas import DetectorNumber

g1_doc = DetectorNumber.find_one(datasource='/path/to/file.csv', version='v1', field='g1')
g1_value = g1_doc.value
g1_error = g1_doc.uncertainty

The path can also be a github URL or any other URL supported by fsspec.

from xedocs.schemas import DetectorNumber

g1_doc = DetectorNumber.find_one(

Supported data sources

  • MongoDB collections

  • TinyDB tables

  • JSON files

  • REST API clients

Please open an issue on rframe if you want support for an additional data format.

If you want a new datasource to be available from a schema class, you can register it to the class:

from xedocs.schemas import DetectorNumber

DetectorNumber.register_datasource('github://org:repo@/path/to/file.csv', name='github_repo')

# The source will now be available under the given name:

g1_doc = DetectorNumber.github_repo.find_one(version='v1', field='g1')
