(Don't rely on this list being complete!)

+ Maybe restructure NodeValue

+ Add sop:XYZ for builtin XYZ to the library.
  
+ Extensions: EXT :list(?x, ?item) and FILTER :isListMember(?list, ?item)

+ Sharing utility code with Joseki
  Convert: HttpContentType; check for others
  
+ Planning order: UNIONs with optionals in them.
  Break into constituent blocks (disjunctive normal form) and reorg.
   
+ Core

+ Function library
  maths: abs(), sqrt() floor() ceiling()

+ Tests
  + More tests
  + Organise DAWG tests : include manifest; copies of latest tests.
  + Test XML result sets
   
+ Add pattern to EXT :qname(args) { pattern }  
  # UNSAID this way? 

+ Engine1
  + Expression optimizations
  + Remove mark? Check argument lists and rationalise order [low priority]
    
+ Parsing
  + XML serialized form parser (prototype) [low priority]
  + \U parsing (32 bit unicode) [Not possible for Java 1.4]

+ Serialization
  + Sort up SerilizationConext
  + Use ";" and "()" in ARQ/SPARQL pretty printing
  + Finish abstract, plain/debug and XML serialzers (prototype) [low priority]

+ Results
  Formatting: reorg
   + ResultSetFormatter.format(results)
     ResultSetFormatter.format(results, processor)
       String myQuery = ...;
       Query query = QueryFactory.getQuery( myQuery );
       ResultSet results = query.exec();
       ResultSetFormatter.format(results, new CustomResultSetProcessor());

+ Application framework
  + "class QuerySelect implements ResultSet "
    which is an QueryExecution and a ResultSet
    Not worth it.
    
  + Modular formatter.
    Plug-ins for formats.
  + Redo examples; make sure documentation is right.

+ System
  + Need to ensure models are loaded once (per query execution - and wider)
  + Integrate a meta-model (GRAPH SYSTEM or similar design)

+ Build
  Check dist/ tree
