DATALAD-EXTRACT-METADATA(1)

📦 version 0.15.5, in ubuntu jammy

💖 datalad extract-metadata 💖

okay bestie, welcome to the datalad extract-metadata page, straight outta the General Commands Manual. this is a datalad command and it's about to run one or more of DataLad's metadata extractors on a dataset or file. yes. that's the whole vibe. let's go 🦋

✨ NAME ✨

datalad extract-metadata — run one or more of DataLad's metadata extractors on a dataset or file. no cap, that's literally what it does 🫶

🌈 SYNOPSIS 🌈

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

🎀 DESCRIPTION 🎀

so here's the tea: the result(s) are structured like the metadata DataLad would extract during metadata aggregation. there's one result per dataset/file. one. per. dataset. per. file. periodt 💅

🌸 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 (living its best independent life, main character energy honestly):

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

💅 OPTIONS 💅

  • FILE — path of a file to extract metadata from. constraint: value must be a string. it's giving "just a humble string, but make it metadata" 🍓
  • -h, --help, --help-np — show this help message. --help-np forcefully disables the use of a pager for displaying the help message. forceful. iconic. no pager, no scrolling drama ✨
  • --type NAME — name of a metadata extractor to be executed. bestie, this option can be given more than once. stack those extractors, you're allowed 🧚
  • -d DATASET, --dataset DATASET — "Dataset to extract metadata from. If no FILE is given, metadata is extracted from all files of the dataset. Constraints: Value must be a Dataset or a valid identifier of a Dataset (e.g. a path). yeah it says "all files", so be ready for a whole crowd of results 🙈
  • --version — show the module and its version which provides the command. it's the "who am I and what build am I on" moment 👑
heads up bestie: if you don't pass FILE and you do pass -d DATASET, it's gonna go extract from all files of the dataset. that's not me being dramatic, that's just the option description fr fr.
