> At my company, we found that the auto-OAS generation tools were too brittle and didn't communicate enough information, so we actually do write our own OAS and run automation to make sure it's accurate.

I found all OAS spec authoring tooling to be useless toys when building non-trivial real world specs.

The depths of depravity I’m forced to is as follows:

1. Data model in SparxEA because it’s the tool we have in the depths of govt. Generate XSD from tool

2. XSLT to turn the XSD into matching JSON Schema because I’m old and can still remember how.

3. Hand write the OAS with $ref into JSON schema as appropriate

4. Curate sample payloads to be educationally useful

5. Generate CURL and various code samples

6. Bundle it all into approx 80k lines of machine written wondrousness -

7. ReDoc and Mkdocs to build static website with more documentation

All the work is at data modeling, OAS sample curation and mkdocs documentation

Things I wish JSON and Schema had:

1. An equivalent of xs:decimal that JS would use number & double are just plain useless in real world commerce with dollars & cents and bulk item pricing with 3&4 decimal places

2. Has taken the time to fix rfc3399 and give Dates a Timezone suffix. Too many languages Marshall a date into datetime. How many bugs have I seen where it’s broken in the morning and works in the afternoon because the damn server is running in AU with UTC Timezone and we’re in NZ
