Universal Data Access (UDA)

The UDA API provides plugin driven data abstraction.

The UDA can be either run as a client-server API, running as thin client with all functionality being handled on a remote server, or as fat-client API where both the client access and plugin functionality is run on the local machine.

Licence

UDA is licenced under an Apache 2.0 licence. See LICENCE.txt for details.

Getting UDA

The source code can be downloaded from:

https://github.com/ukaea/UDA/releases/

The UDA git repository can be cloned from:

git clone git@github.com:ukaea/UDA.git

Getting the UDA client

The easiest way to obtain the client is to pip install the python wrapper (pyuda), wheels are uploaded for every tagged release from version 2.7.6. Further details are available on pypi.

pip install uda

For any other use cases please see the documentation to build from source here.

Building UDA Server from source

There are some notes available here in the documentation.

Note that the most up-to-date build script will be the one used for testing in the github CI tests here. This will contain the relevant buld steps for Ubuntu and MacOS. There are also some dockerfiles available here which will show the build steps for some other Linux flavours.

An example installation for ubuntu 22.10 would be as follows.
