With a Triple Store you can model data as RDF triples. Triples are atomic, so they are easy to create/combine/share. The RDF data model can be very powerful - but it's not ideal for all your information and all your applications. Some data is better modeled as documents, which may be mostly structured text plus metadata; or as data, which may be richly structured objects. Ideally you'd want to manage all this data in one place; query across all the data models; and combine data models and queries in some interesting ways. In this talk we’ll describe some real-world projects built on a multi-model NoSQL database – MarkLogic - which lets you manage and search all of these data models, separately and in combination.
We’ll briefly describe the sweet spot for each model; then we'll talk about interesting ways to combine those models, such as having triples embedded in text documents. Then we'll show some projects where the models are used together, including:
- A major media company using triples and documents to manage digital assets and metadata
- A financial services company applying semantics to financial data to do data integration without ETL
- A scientific publisher using semantics to improve access to, and understanding of, scientific journals
- A TV company with an innovative mobile app to search, organize, and recommend movie clips using triples and digital documents

This talk describes three case studies where we have applied controlled vocabularies to help with information discovery and re-use. These examples stretch across the 15 years and highlight some of the developments in thinking about linked data and education during that time.

As law enforcement agencies around the world consider the use of police officer bodyworn cameras to capture critical evidence during interactions with the public, what's being overlooked is how to effectively use the massive amount of video data being uploaded every day. This session will cover strategies for integrating semantics into the use of body camera video for investigations, officer training and public awareness.
