SST-Core is a Golang API / library based on the W3C Semantic Web standards RDF, RDFS, OWL 2, Turtle and TriG. Unlike other general purpose tools in this field, the goal of SST-Core is not to provide a general purpose solution for all possible kinds of usages. Instead, the focus of SST-Core is to effectively support the integration of industrial product data as used by CAD, CAM, PDM, PLM, ERP, LSA and other CAx system. A particular focus is on the support of international standards in this area by providing higher level SST Ontologies that are optimized for AI integration, including:
- Life-cycle Integration (LCI) as defined in the ISO 15926 series for process plants including oil and gas production facilities
- STEP, the STandard for the Exchange of Product model data, ISO 10303 series;
- IEC Common Data Dictionary (CDD), including IEC 61360-4 for electric/electronic components
- ISO/IEC 81346 Standard Series on Reference Designation System (RDS)
- ASD S3000L on Logistic Support Analysis (LSA)
- ISO/IEC 80000 on Quantities and Units
Other main features of SST-Core:
- performance optimized to support cloud applications
- remote SST Repositories for persistent data storage everywhere on the Internet
- GIT like functionality for RDF NamedGraphs and Datasets including Commit, Branches, Diff & Merge
- access control via OAUTH 2
- data analysis and manipulation of semantic web data via both
- late binding: generic, IRIs are checked only during run time
- early binding: IRIs are checked at compile time by using pre-compiled higher level ontologies; ideally suited for converter and GUI development
