2b:null 2c:["$","title",null,{"children":"DAWG Test Suite for SPOCQ | James Anderson | Observable"}] 31:T613,md` [ARQ](http://jena.sourceforge.net/ARQ/algebra.html) proposed a standard textual notation for abstract [SPARQL](http://en.wikipedia.org/wiki/SPARQL) algebra expressions, which it calls 'symbolic SPARQL expressions' ([SSE](http://openjena.org/wiki/SSE)s). The documentation describes expressions which are compatible with [Lisp](http://lispers.org/)'s [S-expressions](http://en.wikipedia.org/wiki/S-expression) and, given appropriate reader and printer support, can serve as the externalization for a model of abstract SPARQL algebra expressions represented as simple lists. This approach has proven invaluable to the development of Dydra's [SPOCQ](http://blog.dydra.com/2011/05/27/sp2b-benchmarks) query engine. In the early phases, [expositions](http://web.ing.puc.cl/%7ejperez/papers/chapter09.pdf) in the literature on SPARQL 1.0 semantics made it relatively easy to implement the query processor in terms of a small collection of Lisp macros which constituted an operational semantics for SPARQL. As the work progressed towards support for [SPARQL 1.1](http://blog.dydra.com/2011/09/07/sparql-11), this abstract algebra model and the SSE notation made it easier to comprehend the intent of the W3C specification and to verify the query processor's performance against the [Data Access Working Group](http://www.w3.org/2009/sparql/wiki/Main_Page)'s evolving test suite. In order to document this aspect of our implementation, we have translated the query expressions from the original SPARQL form into SSEs and present them here for reference. `32:Tcc3,md`#### algebra -
