Entity Matching

sameAs properties exist in the data which we already leverage in the mappers.

Technical Requirements

• Research if using this AS is feasible for our use
• Create a new harvester for the LC ActivityStreams implementation
• Refactor LC mappers
• Refactor LC index loaders

Known Limitations

No response

Example Integration

First, we need to investigate the ActivityStream LC is vending to see if it is feasible for our use. If acceptable, write LC harvesters to grab data via the AS. Refactor the mappers to use the data in this new format (may not be necessary). Refactor the index loaders to use data in the new format.
