stac-validator-cli v0.1.1

NodeJS Stac Validator

Validates a spatial temporal catalog asset based on the specs laid out by Radiant Earth. Uses https://github.com/sparkgeo/node-stac-validator

Versions

In order to denote compatability with the Stac specification, the first stable version will match the first stable version of STAC

Usage

Intended Usage

CLI

stac-validator -l <location> -s <source> -v <version> -t <type>

stac-validator -l https://cbers-stac.s3.amazonaws.com/CBERS4/catalog.json  -s url -t catalog -v v0.6.0

If you're trying this locally, use the following:

node ./src/index.js -l https://cbers-stac.s3.amazonaws.com/CBERS4/catalog.json  -s url -t catalog -v v0.6.0

Similarly, if you're trying to get a file, use the following:

node ./src/index.js -l ./sample/test.json  -s file -t catalog -v v0.6.0

There will be deep nested searching, to be released at a later date.

Example Responses

Success

A successful response returns an object with a success boolean, as well as a verified_files, which provides a series of responses.

  {
    success: true,
    responses: [
      {
        valid: true,
        location: '<location of file>',
        errors: []
      }
    ]
  }

Failure

A failure response shares the success and verified_files attributes. In addition, it adds a new attribute called errors. The errors object is flat, meaning that there should be no nester arrays of objects present.

The errors object is subject to change until the first stable release, v0.7.0.

  {
    success: false,
    responses: [
      {
        valid: false,
        location: '<location of file>',
        errors: [
          {
            keyword: '',
            message: '',
          }
        ]
      }
    ]
  }

Roadmap
