Is there a way to generate json data from json schema with multi source json data?

I am currently working with a project to implement data fusion / data integration. Now I can find the technology to get json schemas from json data. But how could I integrate different json attributes into the target json schema. My final target is to implement the json data fusion by configuration on a web page. Is there any solution or any open source implementation I could take referrence? Thank you so much.
Please allow me to explain it more clearly. I could define a target json schema, and its attributes should be filled by other json data's attributes (the json may come from multi source).

Writing multiple type of data into a list for it to be accessed by multiple threads

I send JSON's to my app via Postman in a list with a type of mapping(CRUD) to send it to my database.
I want my controller to put all this data, from multiple senders, in a list that will send the information to my DB. The problem is that i don't know how to store in the same list the Json and the Mapping, so when my threads do their work to know if that json must be inserted, updated, deleted and so on.
Do you guys have any ideea ?
PS: It is a spring-boot app that need to be able to send 12000 objects ( made from that jsons ) to the db.
I don't see a reason for putting all data in one list and sharing it later, each HTTP request receives own thread.
On decent server you can handle couple thousands of requests/sec which perform simple CRUD operations.

How to get table data from Wikipedia page?

Is there somebody who knows how to use the Wikipedia API to get JSON or XML data out from a table on a specific Wikipedia page?
Is there maybe a different way to do this?
For example from here https://en.wikipedia.org/wiki/List_of_action_films_of_the_2010s
You can use curl (or use any other method/tool) to retrieve and/or parse a Wikipedia-URL via the public API. Here are two examples that should help you:
Retrieval of List_of_action_films_of_the_2010s:
JSON unparsed via the query action
JSON parsed via the parse action
Next, you would need to parse for and/or select the sub-elements relevant for your analysis. In this case I would assume: wikitable elements.
For reference and a detailed explanation, you can have a look at the general API page of MediaWiki and at the list of parameters on how to use the API to parse Wikipedia pages for certain data elements.

Google Closure JSON data submission with nested objects?

I've been using Google Tools (library, templating) for almost a year... and I came to the point where a I have to connect the backend with all the templates i've been working on. The backend receives the data in JSON format.
Here's my problem. I want to submit a JSON that represents my object model in the backend and I know closure library offers this...
var json = goog.json.serialize(goog.dom.forms.getFormDataMap(form).toObject());
Problem is that the method getFormDataMap returns a goog.structs.Map which works like a hashMap... It means that all values of the form submitted are nested into arrays.
I was wondering if anyone has found a solution to this. I know that there is some library that does the trick like this one (https://github.com/maxatwork/form2js) but I can't believe that closure doesn't have anything to deal with this problem.
Thanks a lot !
why not access the data yourself and build the data structure you require, it is not like this will be a bottleneck of any sorts.

parse json data in template Google App engine python

I am storing json data in the database in my google app engine, There is no problem in stroing the data to DB, But I am not sure how to parse it in the view, For e.g I get all the topics from my MODEL and pass it to the view which is using webapps template (I am not sure its django or jinja2 but it is the default provided by GAE), now my Model objext has one atribute which contains json, I want to parse this json in view without javascript as I am passing the object via template, can any one suggest me how to do it.
for e.g. I query the app engine as
topics = Topic.all()
//topic have many attributes including an attribute tags which contains json string
//["test", "somekeyword"]
I parse this string as individual tags in my view, Can I manipulate this list of objects in python to store as disctionary instead of tags when I retrieve it ? or is there a way to convert it to dictionary in django ?
P.S: I cant parse the json in my handler as the model will have multiple entries and parsing and storing these entries will be difficult
The webapp template language is Django (by default a rather old version). I think you have to change your requirements -- you can parse JSON in Python or in Javascript, but the Django template language is (intentionally) too weak to do that. Maybe show us some samples of the data you want to work with?
