What is OpenSchemas?

OpenSchemas is a sibling of BioSchemas to support schema.org to provide data interoperability for open science. The specifications here are related to technology, high performance computing, infrastructure and research computing. Users are encouraged to use this markup to provide structured understanding to content that drives programmatic discovery.

The main outcome of Bioschemas is a collection of specifications that provide guidelines to facilitate a more consistent adoption of schema.org markup within the life sciences.

Bioschemas started as a community effort in November 2015. It operates as an open community initiative with more than 200 people from a wide variety of institutions. You are welcome to join the community.


Schema.org provides a way for us to add semantic markup to web pages. It describes ‘types’ of information, which then have ‘properties’. For example, ‘Event’ is a type that has properties like ‘startDate’, ‘endDate’ and ‘description’. If types or properties needed in the life sciences are missing, then Bioschemas proposes their adoption by Schema.org.

Schema.org is a community effort supported by the main search engines, and is already widely implemented across the web.

OpenSchemas for generic types

Schema.org defines common generic types like events and datasets which can be used in many disciplines. Openschemas is working on specifications to improve the description of generic types in open sciences, and specifically those that might not fit cleanly into the category of "iife sciences." The dataset markup properties that Openschemas specifies as mandatory will also make them findable by Google's Dataset Search.
