Possible categories:

* queries (not for Fuseki logging - that is better done with Fuseki's logs which include code for an NCSA format log output)
* algebra from query, before and after algebra optimization
* execution of algebra
** Some degree of extensibility for new engines to add their own categories
* Remote requests
** Direct remote call from the application e.g. {{QueryExecutionFactory.sparqlService}}
** From within a query e.g. {{SERVICE}}

> "Explain" capabilities in ARQ are provided like logging levels with levels ALL, INFO, FINE and NONE. For example, Algebra is printed at level FINE but that implies level INFO, which includes queries.  
> Instead, categories would be better so that a "mix and match" of various explanations could be set to give a more focused output.
> This JIRA is for collecting suggestions, requests and contributions for a more extensive "Explain" capability.
