Example schema: JSON Patch

[Francis Galiegue]

JSON Patch is a very powerful IETF draft allowing to patch any JSON
value. Its operations are dead simple. So simple in fact that it took
me 10 minutes to write this:

https://github.com/fge/json-schema-validator/blob/master/src/main/resources/json-patch.json

Link to the draft:

http://tools.ietf.org/html/draft-ietf-appsawg-json-patch-10

Given its simplicity, now you understand why I see its uses for JSON Schema.

I will certainly implement it as a means to modify them!

We should probably have a set of such example schemas for existing formats somewhere on the website.

Ah - I see you made the same suggestion on the GitHub group. :)

https://github.com/fge/json-schema-validator/blob/master/src/main/resources/json-patch.json  returns a 404 - does this JSON-patch schema exist somewhere else now? I cloned the repo and found no *patch*.json files.

https://github.com/fge/json-schema-validator/blob/master/src/main/resources/json-patch.json  gives a 404

I did find https://github.com/fge/sample-json-schemas/blob/master/json-patch/json-patch.json

(though that is based on draft-ietf-appsawg-json-patch-04 which is quite old)

That would be:

Strange, I though I had mentioned the move quite some time ago...

Hi ,

   I am new to Json stuff i.e. JSON PATCH.

I have scenario where I need to figure out between two version of Json files of same object, for that I am using json-patch-master.

But unfortunately the patch generated interpreting it differently i.e. the order differently hence getting unexpected/invalid results. 

Could anyone help me how to preserve the order while generating Json Patch ?

Here is the actual example.

Original Json file :

[ {

  "name" : "name1",

  "roolNo" : "1"

}, {

  "name" : "name2",

  "roolNo" : "2"

}, {

  "name" : "name3",

  "roolNo" : "3"

}, {

  "name" : "name4",

  "roolNo" : "4"

} ]

Modified/New Json file:  i.e. removed 2nd node of original file.

[ {

  "name" : "name1",

  "roolNo" : "1"

}, {

  "name" : "name3",

  "roolNo" : "3"

}, {

  "name" : "name4",

  "roolNo" : "4"

} ]

Patch/Diff Generated :

[ {"op":"remove","path":"/3"},

{"op":"replace","path":"/1/name","value":"name3"},

{"op":"replace","path":"/1/roolNo","value":"3"},

{"op":"replace","path":"/2/name","value":"name4"},

{"op":"replace","path":"/2/roolNo","value":"4"}]

Very time I generate Diff/Patch it is giving different path/diff results.

And moreover the interpretation is different i.e. order is not preserving.

Is there any way to get expected results i.e. [ {"op":"remove","path":"/1"} ] , in other words generated a patch/diff based some order so will get what is expected. ?

How to handle this kind of scenario ?

Please help me.

Thank you so much.

Hello,

This isn't really the mailing list to ask for this. Note that the
generated patch is ultimately correct.

Also, I know that _I_ have a JSON Patch implementation which is able
to generate diffs, but there may be others, so which one are you
referring to? You should open an issue on the issue system of that
particular implementation instead.

Sorry sir,

   As you are expert in json I thought you could give some clue.

Unfortunately json-patch group not letting me send query...hence I posted here.

Anyhow sorry.

Thank you.
