A nanopublication is the smallest unit of publishable information. This information can be about anything, for example a relation between a gene and a disease or an opinion. Nanopublications are fully expressed in a formal and machine-interpretable way. With nanopublications, it is possible to disseminate individual data as independent publications with or without an accompanying research article. Furthermore, because nanopublications can be attributed and cited, they provide incentives for researchers to make their data available in standard formats that drive data accessibility and interoperability. Nanopublications have the following general structure:
As can be seen in this image, a nanopublication has three basic elements:
- Assertion: The assertion is the main content of a nanopublication in the form of an small atomic unit of information
- Provenance: This part describes how the assertion above came to be. This can include the scientific methods that were used to generate the assertion, for example a reference to the kind of study that was performed and its parameters.
- Publication Info: This part contains metadata about the nanopublication as a whole, such as when and by whom it was created and the license terms for its reuse.
Nanopublications are implemented in the language RDF and come with an evolving ecosystem of tools and systems. They can be published to a decentralized server network, for example, and then queried, accessed, reused, and linked.
