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

+ Implement a binary result format : http://lists.w3.org/Archives/Public/public-rdf-dawg/2005OctDec/0131
  reader and writer + rset support

+ CONSTRUCT * where no graph

+ Property paths

+ Add a looser regex mode (any literal / implicit str())

+ Magic Properties
    http://www.jena.hpl.hp.com/ARQ/list#
    +rdfs:member
    
  + Important special case : transitive properties.
  + ext :trans(?s, URI, ?o)
  + Finish documentation (library.html, extension.html)
  + Check dynamic loading 
  + Fix list ops?
  
+ Extensions / Additional stage naming confusion

+ "util" split into "util" and "shared"

+ Command-line setting of config properties.

+ Documentation
   Alternative syntactic forms (N3 like stuff) / tutorial
   app_api.html needs reviewing - rest of non-tutorial documentation
   
+ Expressions in SELECT clause 
  SELECT (?x*?y) AS ?z
  SELECT lang(?z) AS ?z

+ Long term : the need for testing for two of a thing (validation) and non-existances
  e.g. Find "<x> :p 1 ; :p 2 ."

+ Commands to accept windows path names "\"
  IRI Progress

+ TestItem has outlined its usefulness (??)

+ SPI
  javadoc for extensions

+ testing/ARQ/ExprDatatypes has poor coverage (or is mis-named!)

+ Tests
  + Utility to find duplicate tests (hash the query)
  + ARQ/General - organise
  + Library and extension tests
  + Printing tests - syntax tests + equality round tripping - done in qparse
    TestSerialization
    NodeValue.asNode() tests
  + Test XML result sets
  + qtest and http: test sets.

+ Core
  [low] Consider ElementBasePattern (again) = List<ElementTriplePattern>
    Better to enhance ElementGroup to auto allocate ElementBasePattern
    when addTriple used
  May break parse tree rewrite
  
+ FOAF:person describe handler

+ build.xml rework
  Check dist/ tree
  javadoc-all to website
  Jena build : include bin and bat/ files from ARQ

+ ResultSet
  + package.html(?) for all the formatters.
  + Tidy up TextOutput for reuse.

+ XML results: process xml:lang on other elements than just <literal>
  Documentation for XML result set processing

+ Extensions and library
   Set operations
   Exists, in, all, difference (need graph patterns?).
   Generalize extensions:
     -- All extensions
     EXT [ :qname{pattern}() ] 
     EXT [ :qname(){pattern} {pattern} ... ]  // Set difference, exists
     EXT {pattern} :qname() -- All required / is :qname after/before?
     EXT :qname({pattern}|Expression, ....)

+ Sharing utility code with Joseki
  Convert: HttpContentType; check for others
   
+ Serialization
  + Need to take into account subject width across multiple chunks
  + One-conneced bNodes
  + Lists
  + Expressions - outer level does not need () - also SortCondition
  + SPARQL/X (via DOM/JDOM) and SPARQL/R

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

+ Some way to produce binaries for command line apps
  GCJ/Mingw
  Or a "local server" for the command line.
