This directory has four example files in JSON / JSON-LD (JSON-LD with most of the weirdness hidden in the @context header, which will eventually be remotely referenced from gs1.org)
The directory also contains two validation files:
Initially developed by Danny Haak (Nedap) and slightly modified by Mark Harrison
To try out JSON Schema validation of the examples, you can use online tools such as:
https://www.jsonschemavalidator.net/
https://json-schema-validator.herokuapp.com/
Paste the contents of EPCIS-JSON-Schema.json into the 'Schema' window (which usually appears first or to the left) Then paste the contents of one of the EPCIS example files into the 'Data' window (which usually appears second or to the right) Any validation errors will be reported by the tools
Initially developed by Mark Harrison
To try out Shape Constraint Language (SHACL) validation, you can use this online validation tool:
Paste the contents of EPCIS-SHACL.ttl into the 'Shapes Graph' window on the left-hand side Paste the contents of one of the EPCIS example files into the 'Data Graph' window on the right-hand side. Press both 'Update' buttons under the two main text areas where you have just pasted in contents of files.
If there are validation errors, they will appear in the Validation Report window (bottom-right). If there are no validation errors, the Validation Report window should be empty.
The contents of any of the EPCIS example files can also be pasted into this online tool:
https://json-ld.org/playground/
This JSON-LD playground tool perforns a basic check that the data is valid JSON-LD - although it has no awareness of our EPCIS-SHACL.ttl file. The JSON-LD playground tool also performs conversion of JSON-LD data into other Linked Data formats such as N-Quads or Normalised (both of which are RDF Turtle format, consisting of Subject-Predicate-Object or Subject-Property-Value triples. The JSON-LD playground tool now also includes a tabular view, as well as a visualisation as a branching diagram.
JSON Schema may be familiar to many Web / app developers, particularly since the Open API specification makes use of it.
Further information about JSON Schema can be found at: https://json-schema.org/
Shape Constraint Language (SHACL) may be less familiar, even though it is a relatively new W3C technical recommendation (standard)
The W3C SHACL standard is available at: https://www.w3.org/TR/shacl/
If you notice any validation errors in the examples, please contact mark.harrison@gs1.org so that we can investigate further.
Please only edit the existing JSON Schema file or SHACL file if you know what you are doing!
