Let me explain by the example of pubspec.yaml. In the Android Studio settings, there is a section JSON Schema Mappings where you can select different schemas for the files. For example, for pubspec.yaml the scheme from https://json.schemastore.org/pubspec.json.
The schema for analysis_options.yaml on json.schemastore.org is not available, and the schema for pubspec.json does not fit.
There was an open issue: json schema for analysis_options.yaml
Question: Where can I find a working schema for analysis_options.yaml?

I need some guidance on how to proceed with a problem.
Our integration team receives xml files which are converted to json and sent to pub/sub. We then ingest the json files (or are supposed to) into bigquery.
The problem is that the xml files do not include all possible objects or values all the time. So, I cant create a correct schema in bq to receive the json files. I got the xsd file with an extension file which gives me all possible objects but I don't know how to convert this to a correct bq schema.
Do you have any suggestions on how to create a bq schema from xsd files? I was thinking that if I create an xml file with dummy data (including all objects and more than one object when creating repeated objects) with help of the xsd maybe that xml file may be converted to json and then use the auto-schema detection of bq.
Any suggestions?
Thanks,
Cris
If you have the XSD schema files, you can convert these to a valid JSON schema. There are a few tools that can help you to accomplish this.
Keep in mind that the tools are for general purposes and not for the particular case of BigQuery, so you'll have to tune the result to get a valid JSON schema. For this check the components of a BigQuery schema, and for quick reference the sample provided in the documentation.
I'm creating an npm package which contains a schema file, set.schema.json. I'm wondering how I can set this as the $schema of a JSON file in another project with this package installed as a dependency. I'm mainly using the schema for IDE suggestions, rather than validation.
JSON Schema does not specify a way to do this.
Any way you want to do this needs to be supported by the IDE in question.
The full schema here is too large for program we are using and need to break up. Looking for way to make say GetAccountBalance module and create its own schema. Schema Editor validates full as a good schema.
Parsed using the full JSON file, getting invalid schema regardless of how try.

I want to convert JSON files to CSV in nifi. We can achieve this in Python and other programming languages and have multiple articles on it. I have multiple JSON files and each file has different schema(one specific file will have one schema only). I can see there are templates to convert CSV to JSON and other conversions. But I didn't see any template to convert JSON data to CSV. I have gone through the article https://community.hortonworks.com/articles/64069/converting-a-large-json-file-into-csv.html ,however here we are hard coding the schema. As I have multiple files and each file has different schema, I can't hardcode the schema. Any suggestions please.
Conversion between formats is typically done through ConvertRecord by plugging in the appropriate record reader and record writer, in this case a JSON reader and CSV writer.
To make use of the record processors you need to defined Avro schemas for your data and put them in a schema registry, NiFi provides a local one.
There are lots of examples and posts out there about the record stuff, this slide deck shows an example of CSV to JSON, but would be easy to reverse the situation for your scenario:

Is there an existing program that helps forming a JSON Schema?
There's this great tool to get you started on generating a JSON Schema: http://www.jsonschema.net/ . Just feed a sample JSON files and out comes out a JSON Schema that you can then tweak.
Check this demo one. It is at an early stage but you can already edit jSON documents with a schema constraint as well as design a Schema itself.
And here is an official thread about Schema-based JSON editor:
You can use Orderly. They have DSL for schema description and you can try it online.
You could try this one (XML ValidatorBuddy) which is actually an XML editor but it also supports JSON and especially JSON Schema editing. The editor is a Windows desktop application and can do auto-completion and syntax-coloring for JSON schema files. You can also validate your JSON files against JSON schema.
You can do this in Liquid XML Studio, but its a commercial product
This isn't exactly something that'll help you with a 'schema', per se, but it's a visual way to navigate and manage JSON data.
