-----------------------------------------
Hi Claus,
a short intermediate status on comparison of both Java based JSON schema
validators. This https://github.com/agebhar1/json-schema-validator-battle is
the repository. It's a Maven based multi-module Java project. A module for each
JSON schema validator, because of there dependencies and one for schema and
example resources.

The needed dependencies for `fge/json-schema-validator` are much more than that
of `everit-org/json-schema`. But `fge/json-schema-validator` depends on the
popular Jackson library which might cause some problems if another version is
already on the classpath. Both depends on Google's `guava` in which
`everit-org/json-schema` makes use of current version 19 whereas
`fge/json-schema-validator` on 16.0.1.
*Failure Reports*
Schema:
{
"$schema" : "http://json-schema.org/draft-04/schema";,
"type": "object",
"required": [
"a"
],
"properties": {
"a": {
"type": "string"
},
"b": {
"type": "number"
},
"c": {
"type": "boolean"
}
}
}
Failing Example:
{
"a": "foo",
"b": "1",
"c": false
}
`everit-org/json-schema`:
#/b: expected type: Number, found: String
`fge/json-schema-validator`:
{
"level": "error",
"schema": {
"loadingURI": "#",
"pointer": "/properties/b"
},
"instance": {
"pointer": "/b"
},
"domain": "validation",
"keyword": "type",
"message": "instance type (string) does not match any allowed primitive type
(allowed: [\"integer\",\"number\"])",
"found": "string",
"expected": [
"integer",
"number"
]
}
So I must revise my statement on failure/error reporting -
`fge/json-schema-validator` is obviously more precise.
Hopefully in the next week I would add more sophisticated examples, maybe based
on tests from `fge/json-schema-validator` and/or `everit-org/json-schema`. JSON
schema also supports modular style through referencing (sub) schemas. Both
implementations provide support which need some investigations.
