Final Thoughts

"I have a pitch meeting in a week. Can you build me a website that has all the articles, video, images related to my last three grants?"

What are the data use cases we may encounter?

"Discovery Channel called, they want all the video we have on whale activity near Georges Bank where Michael Moore's whale monitoring instrumentation was used."

'14 NY Times Innovation Report

"The Times is woefully behind in its tagging and structured data practices….Structured data problems prohibit the Times from automating the sale of photos and keep Times stories from doing as well in search rankings as they should." (p. 41)

“Just adding structured data, for example, immediately increased traffic to our recipes from search engines by 52 percent.” (p.44)

They spent “a huge sum to retroactively structure the data.” Structured data problems prohibit the Times from automating the sale of photos and keep Times stories from doing as well in search rankings as they should. (p. 41)
