Proposal

A CLI tool that leverages Qlik Core to report on basic metadata about a QVF.

Motivation

Qlik Core leverages QVF files to store data models that you can interact with via the Qlik Associative Engine. These QVF files, like any file, are black boxes until you open them up and look inside. While developing solutions on top of Qlik Core, it can be difficult to understand what is going on with your QVF - what data is in there, what objects, etc. Writing scripts via enigma.js or RxQ to simply get a list of fields from a QVF that you are building on top of is cumbersome.

Eventually, I expect that Qlik, partners, and customers will build an ecosystem of nice dev tools for working with Core. In the meantime, I propose a CLI tool as a first step that can provide key metadata about QVFs in a quick and easy way.

Existing Solutions

There are no published solutions (that I'm aware of) today for easily working with Core across platforms. [Alex Karlsson](https://twitter.com/mindspank/status/99111532994953216
