APIs for query support Link to API4KB Main Page

  • Ask, tell …? queries with side effects? what do you do with inferred knowledge based on the query (post it, not)?
  • Read-only (boolean - can/can't satisfy, or extract if available)
  • Read-write API (i.e. with side effects that can update the KB)
    • Inform – write something to the KB, but only commit if consistency is preserved (flag)
    • Inform/reason/query – write something to the KB, reason over the KB, query to get revised results
      • Hypothetical reasoning – inform/reason/query/rollback
      • Or without rollback, meaning commit the results, but only if consistency is preserved
  • Service discovery (e.g. query to a portal for services pertaining to a certain subject)
  • Determining service capabilities
    • Determine which “semantic profiles” (e.g. OWL 1.1 Full, EL, RL, QL, Common Logic, RDF Inference, …) the service recognizes
    • Determine which formats the service recognizes (e.g. RDF/XML, RDF/N3, …)
    • Determine which query languages are recognized (e.g. SPARQL, graph query language, OWLQL, etc)
  • Response should address which, if any capabilities are mandatory, optional
  • Response should address consistent naming - declare which URIs will be used to identify capabilities

Most of these APIs may require various compliance levels, so that people can support read-only, or inform but not inform/reason/query, or not hypothetical reasoning … etc.
