NAME

       datalad metadata - metadata reporting for files and entire datasets

SYNOPSIS

       datalad  metadata  [-h] [-d DATASET] [--get-aggregates] [--reporton TYPE] [-r] [PATH [PATH
              ...]]

DESCRIPTION

       Two types of metadata are supported:

       1. metadata describing a dataset as a whole (dataset-global metadata), and

       2. metadata for files in a dataset (content metadata).

       Both types can be accessed with this command.

       Examples:

       Report the metadata of a single file, as aggregated into  the  closest  locally  available
       dataset, containing the query path::

         % datalad metadata somedir/subdir/thisfile.dat

       Sometimes  it is helpful to get metadata records formatted in a more accessible form, here
       as pretty-printed JSON::

         % datalad -f json_pp metadata somedir/subdir/thisfile.dat

       Same query as above, but specify which dataset to query  (must  be  containing  the  query
       path)::

         % datalad metadata -d . somedir/subdir/thisfile.dat

       Report any metadata record of any dataset known to the queried dataset::

         % datalad metadata --recursive --reporton datasets

       Get  a  JSON-formatted  report  of aggregated metadata in a dataset, incl.  information on
       enabled metadata extractors, dataset versions, dataset IDs, and dataset paths::

         % datalad -f json metadata --get-aggregates

OPTIONS

       PATH   path(s) to query metadata for. Constraints: value must be a string [Default: None]

       -h, --help, --help-np
              show this help message. --help-np forcefully  disables  the  use  of  a  pager  for
              displaying the help message

       -d DATASET, --dataset DATASET
              dataset  to  query.  If given, metadata will be reported as stored in this dataset.
              Otherwise, the closest available dataset containing a query path will be consulted.
              Constraints:  Value  must  be  a Dataset or a valid identifier of a Dataset (e.g. a
              path) [Default: None]

       --get-aggregates
              if set, yields all (sub)datasets for which aggregate metadata are available in  the
              dataset.  No  other  action  is  performed,  even if other arguments are given. The
              reported results contain a  datasets's  ID,  the  commit  hash  at  which  metadata
              aggregation  was  performed,  and the location of the object file(s) containing the
              aggregated metadata. [Default: False]

       --reporton TYPE
              choose on what type result to report on: 'datasets', 'files', 'all' (both  datasets
              and  files),  or  'none'  (no  report).  Constraints:  value must be one of ('all',
              'datasets', 'files', 'none') [Default: 'all']

       -r, --recursive
              if set, recurse into potential subdataset. [Default: False]
