There are many hundreds of data repositories on the Web, providing access to tens of thousands—or millions—of datasets. National and regional governments, scientific publishers and consortia, commercial data providers, and others publish data for fields ranging from social science to life science to high-energy physics to climate science and more. Access to this data is critical to facilitating reproducibility of research results, enabling scientists to build on others’ work, and providing data journalists easier access to information and its provenance. For these reasons, many publishers and funding agencies now require that scientists make their research data available publicly.

However, due to the volume of data repositories available on the Web, it can be extremely difficult to determine not only where is the dataset that has the information that you are looking for, but also the veracity or provenance of that information. Yet, there is no reason why searching for datasets shouldn’t be as easy as searching for recipes, or jobs, or movies. These types of searches are often open-ended ones, where some structure over the search space makes the exploration and serendipitous discovery possible.

To provide better discovery and rich content for books, movies, events, recipes, reviews and a number of other content categories with Google Search, we rely on structured data that content providers embed in their sites using schema.org vocabulary. To facilitate similar capabilities for datasets, we have recently published new guidelines to help data providers describe their datasets in a structured way, enabling Google and others to link this structured metadata with information describing locations, scientific publications, or even Knowledge Graph, facilitating data discovery for others. We hope that this metadata will help us improve the discovery and reuse of public datasets on the Web for everybody.
