Enterprise linked data - open or closed, Andreas Blumauer, Keynote SMWCon 2014

Linked Data has become a broadly adopted approach for information management and data management not only by government organisations but also more and more by various industries.

Enterprise linked data tackles several challenges like the improvement of information retrieval tools or the integration of distributed data silos. Enterprises understand better and better why their information management should not be limited by organisational boundaries but should rather consider to integrate and link information from different spheres like the public internet, government organisations, professional information providers, customers and even suppliers.

On the other hand, enterprise IT architects still tend to pull down the shutters wherever possible. The continuation of the success of the Semantic Web doesn't seem to be limited by technical barriers anymore but rather by people's mindsets of intranets being strictly cut off from other information sources.

In this talk I will throw new light on the reasons why metadata is key for professional information management, and why W3C's semantic web standards are so important to reduce costs of data management through economies of scale. I will discuss from a multi-stakeholder perspective several use cases for the industrialization of semantic technologies and linked data.
