# 10000ft overview

DataLad makes data management and data distribution more accessible.
To do that, it stands on the shoulders of [Git] and [Git-annex] to deliver a
decentralized system for data exchange. This includes automated ingestion of
data from online portals and exposing it in readily usable form as Git(-annex)
repositories, so-called datasets. The actual data storage and permission
management, however, remains with the original data providers.

The full documentation is available at: http://docs.datalad.org

# Extensions

A number of extensions are available that provide additional functionality for
DataLad. Extensions are separate packages that are to be installed in addition
to DataLad. In order to install DataLad customized for a particular domain, one
can simply install an extension directly, and DataLad itself will be
automatically installed with it. Here is a list of known extensions:

- [tracking web resources and automated data distributions](https://github.com/datalad/datalad-crawler) [](https://GitHub.com/datalad/datalad-crawler/releases/)
- [neuroimaging research data and workflows](https://github.com/datalad/datalad-neuroimaging) [](https://GitHub.com/datalad/datalad-neuroimaging/releases/)
- [support for containerized computational environments](https://github.com/datalad/datalad-container) [](https://GitHub.com/datalad/datalad-container/releases/)

- [webapp support](https://github.com/datalad/datalad-webapp) [tech demo]

with a ``datalad`` tag. NeuroStars.org is a platform similar to StackOverflow
but dedicated to neuroinformatics.

# Installation

## Debian-based systems

On Debian-based systems, we recommend to enable [NeuroDebian] from which we
provide recent releases of DataLad. Once enabled, just do:

apt-get install datalad

## Other Linux'es, OSX via pip

Before you install this package, please make sure that you [install a recent
version of git-annex](https://git-annex.branchable.com/install). Afterwards,
install the latest version of `datalad` from
[PyPi](https://pypi.org/project/datalad). It is recommended to use
a dedicated [virtualenv](https://virtualenv.pypa.io):

# create and enter a new virtual environment (optional)
virtualenv --python=python3 ~/env/datalad
. ~/env/datalad/bin/activate

# install from PyPi
pip install datalad

By default, installation via pip installs core functionality of datalad
allowing for managing datasets etc. Additional installation schemes
are available, so you could provide enhanced installation via
`pip install datalad[SCHEME]` where `SCHEME` could be

- `tests`
to also install dependencies used by unit-tests battery of the datalad
- `full`
to install all dependencies.

There is also a [Singularity container](http://singularity.lbl.gov) available.
The latest release version can be obtained by running:

singularity pull shub://datalad/datalad
