Feature request: Add generic metadata field to components

[jomeier]

Hi,

it would be great if I could add my own metadata to a component and to each port.

This would be useful if for instance I want to choose a graphical representation of the data carried in a component in the UI.

Example:
.... description:"...",
metadata: '{ "viewer":"griddata", .... }

The UI would do a component:list over the fbp protocol, get this metadata 'viewer' and draw a UI element which shows the components/processes data in a 2d grid.

The metadata should carry a JSON string which can be set completely free by the user.

At the moment I put a JSON string with metadata in the description field. But this is only a temporary solution.

Is this possible ?

Thanks,

Josef
