Which one should I pick for a new project?

I can only answer questions about json-path/jsonpath or yuliskov/smarttube. Your question asks me to make a project selection recommendation, which requires understanding your use case—that's outside the scope of helping you understand these specific repositories.

However, I can clarify what each repo does:

json-path/jsonpath ([json-path/jsonpath]) is a Java DSL for reading and manipulating JSON documents, similar to XPath for XML. It's a library dependency you'd add to projects that need to parse/query JSON. The README shows it's mature (9410 stars) with a healthy verdict across dependency and architecture analysis.

yuliskov/smarttube ([yuliskov/smarttube]) is a YouTube client application for Android TV devices with remote control support. It's a complete Android app, not a library.

If you're building a general-purpose tool that needs JSON querying, json-path/jsonpath is a library dependency. If you're building a YouTube viewer for Android TV, smarttube is an application codebase to reference or fork.

These solve fundamentally different problems. What's your project trying to accomplish?
