Dear RDF Data Access WG,
Complementary to the recent work of the RDF Data Access Working Group
[1],
we have compared six proposals for RDF query languages.
The report, the use case data, and the queries are available online [2].
It compares the following native RDF query languages:
- RDQL
- RQL
- SeRQL
- Versa
and the following RDF rule languages, which can be used as query
languages as well:
- Triple
- CWM (Query Language through --filter command line option)
We would be happy to have feedback !

"It IS a long tail, certainly," said Alice, looking
down with wonder at the Mouse's tail; "but why do you
call it sad?" And she kept on puzzling about it while the
Mouse was speaking, so that her idea of the tale was
something like this:----"Fury said to
a mouse, That
he met in the
house, `Let
us both go
to law: I
will prose-
cute YOU.--
Come, I'll
take no de-
nial: We
must have
the trial;
For really
this morn-
ing I've
nothing
to do.'
Said the
mouse to
the cur,
`Such a
trial, dear
sir. With
no jury
or judge,
would
be wast-
ing our
breath.'
`I'll be
judge,
I'll be
jury,'
said
cun-
ning
old
Fury:
`I'll
try
the
whole
cause,
and
con-
demn
you to
death'."
(from Lewis Caroll, Alice in Wonderland, Chapter III,
"A Caucus Race and a Long Tale", 1865)
