What we do
LDIF – Linked Data Integration Framework
LDIF is a novel open-source Linked Data Integration Framework that addresses prevalent Linked Data integration issues for application developers. LDIF translates heterogeneous Linked Data from the Web into a clean, local target representation while keeping track of data provenance.
LDIF is a joint project with the Web-based Systems Group of Freie Universität Berlin and quickly maturing, with support for in-memory, triple store (TDB) and cluster (Hadoop) deployments.
Funding is provided by Vulcan, Inc. as part of its Project Halo.
Consulting
We provide engineering and consulting services to organizations that seek to publish, consume and transform Linked Data.
