Jackson core is a Java library for processing abstractions (aka Streaming API), implementation for JSON. Jackson core is available via the Maven package manager.

Jackson core contains core low-level incremental ("streaming") parser and generator abstractions, which is used by Jackson Data Processor. Jackson core also includes the default implementation of handler types (parser, generator) that handle JSON format.

Jackson core abstractions are not JSON specific, although naming does contain 'JSON' in many places, due to historical reasons. Only packages that specifically contain word 'json' are JSON-specific.

Tidelift works directly with the maintainers of Jackson core to offer maintenance, code improvement, license verification, and security updates so you can use psutil for running processes and system utilization in your app.

You can learn more about Jackson core on the project repo.
