[Feature Request]: Static Schema Definition

[sramazzina]

What would you like to happen?

The purpose of the static schema is to provide a static way to provide tabular layouts to input and output transforms in an Apache Hop pipeline.

Static schemas should:

• Exist per project/customer
• Initially apply to a selected set of input and output transforms (CSV FIle Input, Excel Input, Microsoft Excel Writer, Text file input, Text file output)

Transforms that use a static schema will incorporate the schema definition in the transform’s metadata (embedded in the pipeline’s XML serialization). Also, a new transform called “Schema Mapping” will allow an Apache Hop pipeline developer to map a pipeline stream to a static schema layout.

Very interesting. What kind of problem is being solved here?

It's the first step to catalog integration, let's say you require a specific schema for your output CSV files you can define them and map your stream to match this definition
