WhereHows 
WhereHows is a data discovery and lineage tool built at LinkedIn. It integrates with all the major data processing systems and collects both catalog and operational metadata from them.
Within the central metadata repository, WhereHows curates, associates, and surfaces the metadata information through two interfaces:
- a web application that enables data & linage discovery, and community collaboration
- an API endpoint that empowers automation of data processes/applications
WhereHows serves as the single platform that:
- links data objects with people and processes
- enables crowdsourcing for data knowledge
- provides data governance and provenance based on ownership and lineage
Documentation
The detailed information can be found in the Wiki
Examples in VM
There is a pre-built vmware image (about 11GB) to quickly demonstrate the functionality of WhereHows. Check out the VM Guide
