fine with things as they are. However, the public appear to find it
unnecessarily complex.

The general public are aware of a version of SPARQL that they call
"version 1". There is very little awareness of the protocol being a
part of the spec, so SPARQL just refers to all of it. Most people (who
are interested in these things) are also aware that SPARQL is being
updated at the moment, with most people adopting the moniker "SPARQL

Generally, people don't seem to have an issue with the next version
being 1.1 instead of 2, so that's fine. But when we say that SPARQL
will now be in several parts, with the query language and the protocol
being 1.1 and the update language being 1.0, that's when the confusion

Having different version numbers for different parts of the spec is
forcing a lot of people to be aware of the fact that there ARE
different parts of the spec. That's all well and good for us, but the
majority of people are just trying to figure out how to talk to a
database, and are learning whatever they need to make it work. The
proposed versioning does NOT work for them, and they make up the
majority of potential users.

Contributing to the complexity of the situation, the Update 1.0 spec
depends on the Query 1.1 spec, again mixing version numbers - and
simply to use a single part of the spec (Update).

I get it, you get it, and anyone intimately familiar with SPARQL gets
it, but the spec is being made available for the general public, and
they don't get it.

If I had to explain it to someone (and I often do) then personally I'd
like to say, "SPARQL 1 had two parts. The first part lets me do
queries, and the second part describes how to connect to a SPARQL
server and talk to it. SPARQL 2 also has those parts, expanding
significantly on the capabilities of each. It also has a third part
that lets me update data in a database."

Any versioning scheme that fits into that description (or something
like it) would be supported by me.  :-)
