About SSSOM, A Simple Standard for Sharing Ontological Mappings
SSSOM is a simple metadata standard for describing semantic mappings:
- Introducing a machine-readable and extensible vocabulary to describe metadata of mappings.
- Defining an easy to use table-based format that can be integrated into existing data science pipelines without the need to parse or query ontologies, and that integrates seamlessly with Linked Data standards.
- Implementing open and community-driven collaborative workflows designed to evolve the standard continuously to address changing requirements and mapping practices.
- Providing reference tools and software libraries for working with the standard.
A SSSOM mapping comprises three major components:
- The mapping itself, that is, a triple
<subject, predicate, object>that reflects a correspondence of a
subjectentity, for example a class in an ontology, to an
objectentity, for example an identifier in some database, via a semantic mapping
predicate, such as
- A mapping justification, which the process or activity that led us to consider the mapping to be correct or reasonable (typical examples: labels match exactly; two classes are logically equivalent; a domain expert determined that two terms reflect the same real world concept).
- Provenance metadata, including information about
