A JSON-LD command line interface tool.
npm install jsonld-clijsonld-cli
==========
Introduction
------------
This module provides a command line tool jsonld to manipulate [JSON-LD][]
data. It is written in JavaScript for [Node.js][] and uses the [jsonld.js][]
and [jsonld-request][] libraries. Inputs can be from stdin, URLs, or files.
* [Node.js][]
* [npm][]
``
npm install -g jsonld-cli
`
npx jsonld-cli ...
The jsonld` command line tool can be used to:
* Check JSON-LD for various problematic data.
* Transform JSON-LD to compact, expanded, flattened, or canonized form.
* Transform [RDFa][] to JSON-LD.
* Canonize JSON-LD/RDFa Datasets to [N-Quads][].
To show tool options, a list of commands, or command options:
jsonld --help
jsonld COMMAND --help
To check JSON-LD for some common problems:
jsonld lint "https://example.com/data.json"
To compact a document on the Web using a JSON-LD context published on
the Web:
jsonld compact -c "https://w3id.org/payswarm/v1" "http://recipes.payswarm.com/?p=10554"
The command above will read in a PaySwarm Asset and Listing in [RDFa][] 1.0
format, convert it to JSON-LD expanded form, compact it using the
'https://w3id.org/payswarm/v1' context, and dump it out to the console in
compacted form.
jsonld canonize -q "http://recipes.payswarm.com/?p=10554"
The command above will read in a PaySwarm Asset and Listing in [RDFa][] 1.0
format, canonize the data using the RDF Dataset canonicalization algorithm, and
then dump the output to canonized [N-Quads][] format. The [N-Quads][] can then
be processed via SHA-256, or similar algorithm, to get a deterministic hash of
the contents of the Dataset.
Security Considerations
-----------------------
* This tool is able to read stdin, local files, and remote resources.
* Loading of remote resources may reveal aspects of the data being processed.
* Input data may recursively load remote resources.
* Input data may load arbitrary local files if allowed.
* Processing data that uses untrusted remote resources could result in
unexpected output.
