 APIs for query support [[start|Link to API4KB Main Page]] APIs for query support [[start|Link to API4KB Main Page]]
-   ​* ​SPARQL ​is only one option +   ​* ​Ask, tell ...? queries with side effects? ​ what do you do with inferred knowledge based on the query (post it, not)? 
-   ​* ​Need to evaluate other possibilities +   * Read-only (boolean - can/​can'​t satisfy, or extract if available) 
-      * graph query language +   * Read-write API (i.e. with side effects that can update the KB) 
-      * something like OWLQL +        * Inform -- write something to the KB, but only commit if consistency ​is preserved (flag) 
-      * etc.+        * 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.
