Protocols SPARQL Protocol, HTTP/REST
4s-httpd serves SPARQL query/update at /sparql/ (port 8080, default); its own source (httpd.c) implements a separate /data/ PUT-POST-DELETE graph-load endpoint plus /status/, /status/cache/, /status/size/ and /description/ admin resources, which is the non-SPARQL HTTP API the ruling requires before adding HTTP/REST. Pass A's tag is correct; pass B's rejection doesn't hold against the source.
-
Port to run HTTP SPARQL daemon (4s-httpd) on. Default is 8080.
