Open Archives

Overview

Open Archives is a portal and aggregator of open historical data. By re-using open data from archives and researchers Open Archives makes an innovative portal which makes historical data from indexed sources available to end users in a user-friendly and innovative way. The innovation is especially evident with the automatic linking to other records, people in other data sources and additional context information.

Open data allows for innovation! With this in mind, all data within Open Archives is also provided in an unambiguous manner as open data via an API and OAI-PMH data provider so that other developers can get to work. This makes Open Archives an aggregator of open historical data.

Open Archives is an initiative by Bob Coret (Coret Genealogie).
