Ontology to describing Function as a Service providers and application requirements.
Here is the Roadmap for the development
Resources we leveraged in our ontology:
- time is used to model execution times and other temporal attributes
- locn is used to model location attributes (for example data center location or geographical restrictions)
- dave is used to model relationships between metrics (the ones required by the application or provided by the Execution Environment)
- wd used to fetch existing concepts (locations, programming languages, cpu architecture)
- wdt used to integrate with existing properties (
part offor example) - DCMI Metadata Terms, FOAF, DCMI Metadata elements, OWL, RDF, RDFS, XSD as the base for most relationships/meta-data and restrictions
For the full ontology see this.
For now the Tbox and Abox are mixed in one file, we need to split them up for clarity.
