Re: SPARQL Protocol


That's very interesting. I was only able to skim it quickly. It clearly needs careful study.

- I wonder if the PUT method should not be replaced by "APPEND" as it appends the data to the database.
- There don't seem to be ways of create resources like in webdav. So I don't know if it would be possible to add graphics using this language.
- I wonder how useful this could be if merged with webdav (of which I don't know that much in detail) as a way of querying a webdav repository for example.

Used with RSS 1.0, it could fulfil a similar role as that envisaged
for the Atom Protocol.

[[
The SPARQL Abstract Protocol is made up of seven orthogonal
operations: query, getGraph, getOptions, makeGraph, dropGraph,
addTriples, and deleteTriples.
]]

Its HTTP binding appears to make good use of the available verbs.

(The Sparql query language itself is at
http://www.w3.org/TR/rdf-sparql-query/ )

Cheers,
