DataLad¶
DataLad is a solution that provides decentralised access to data from open data annexes. It provides a command line interface to interact with the technologies it is built on, such as git and Git-Annex to provide functionality such as dataset searches, dataset nesting, dataset collections and git annex file management. This makes it a good candidate for further extensibility using a web interface.
DataLad also comes with support for metadata, with a search command that enables metadata queries via a flexible query language.
