NAME

       datalad  extract-metadata  - run one or more of DataLad's metadata extractors on a dataset
       or file.

SYNOPSIS

       datalad extract-metadata [-h] --type NAME [-d DATASET] [--version] [FILE ...]

DESCRIPTION

       The result(s) are structured like the  metadata  DataLad  would  extract  during  metadata
       aggregation. There is one result per dataset/file.

       Examples:

       Extract metadata with two extractors from a dataset in the current directory and also from
       all its files::

         $ datalad extract-metadata -d . --type frictionless_datapackage --type datalad_core

       Extract XMP metadata from a single PDF that is not part of any dataset::

         $ datalad extract-metadata --type xmp Downloads/freshfromtheweb.pdf
