Provenance generation

This section allows to recostruct the provenance for a given document avaiaible on MetaStore, by taking trace of the Parent fields inside the filled metadata documents.

Select a Schema ID first, and then choose the corresponding Metadata document ID for which you want to obtain the provenance. The provenance is provided in the form of a .json file, which you can save to your local computer.

Info

NFFA sign-in is required to generate provenance

It consists of nested sections (as indicated by highlighted portions) that include details like reference , referenceType , Schema type (also referred to as label ), and possibly parents : an array that carry similar blocks of information describing the current block's parents at a nested level. The keys (e.g. 2a13ccdd-fd33-4f49-bbc3-01d2a48580ff string for highlighted block) correspond to MetaStore document ID if referenceType is MetaStore URI , otherwise are just ID strings without a particular meaning.

To make things clearer, the above provenance document is shown below as graph (generated with JSON Crack ).
