class	Op1 Super class for operators that operate on a single sub-operation (i.e.
class	Op2 Super class for operators that combine two sub-operators
class	OpAssign

class	OpDatasetNames
class	OpDiff
class	OpDisjunction N-way disjunction.
class	OpDistinct
class	OpExt Marker for extension points Execution will be per-engine specific
class	OpExtend This is the operation in stadard SPARQL 1.1 OpAssign is specifically in support of LET.
class	OpFilter
class	OpGraph

class	OpPath
class	OpProcedure General procedure in algebra evaluation (a stored procedure facility) Syntax (ARQ extension): CALL (?x, ?y+3) See also the similary algebra form for property functions.
class	OpProject
class	OpPropFunc Property functions (or any OpBGP replacement) Execution will be per-engine specific
class	OpQuad Algebra operation for a single quad.
class	OpQuadPattern
class	OpReduced
class	OpSequence A "sequence" is a join-like operation where it is know that the the output of one step can be fed into the input of the next (that is, no scoping issues arise).
class	OpService
class	OpSlice
class	OpTable
class	OpTopN Top N from a stream of items - for small N, better than ORDER BY + LIMIT N
class	OpTriple Algebra operation for a single triple.
