Ion Path Extraction API aims to combine the convenience of a DOM API with the speed of a streaming API.

Ion Schema Specification 1.0 Released
05 November 2018
This new specification describes a language and set of constraints used to declaratively constrain Ion values. Types defined by a schema could be used to:
- assert that a value meets specific expectations,
- generate developer-friendly APIs for working with data,
- enable efficient analysis over data that conforms to a type,
- and more!
A reference implementation of Ion Schema is now available as open source software. It is written in Kotlin, and should be considered alpha software.
