Marked data

This is a collection of libraries which offer data provenance facilities and then use that to provide a variety of marked data structures.

The data marks are intended to be similar to, though not entirely the same as data structures seen in other systems as Span or similar. Instead data marks are a combination of that span-like data and also file sources. The intent here being that combining data from multiple sources is a safe and sensible thing to do and that after doing so, it is important to be able to discover where something came from.

Currently we provide:

• marked-data: The core data mark library
• marked-yaml: A deliberately simplified YAML subset which supports data marking
