Hi Jonathan,
The Anzo SPARQL endpoint by default is protected via HTTP Basic
Authentication. Enabling the anonymous access doesn't disable the HTTP
Basic Auth requirement for the SPARQL endpoint.
If you send an HTTP username and password along with your request things
should work as expected. For example you can use the username sysadmin
with password 123 if you still just have the demo defaults. Or since you
have anonymous access enabled, you can use anzo_anonymous as the
username and any password at all.
Also, just a warning for your next step, if you don't specify any graphs
for the dataset of your SPARQL query, Open Anzo treats that as querying
against an empty dataset. Other stores do that differently, treating
that instead as querying against all graphs. In Open Anzo, to bring 'all
graphs' into the query's dataset you need to use the following 'magic'
URL as the SPARQL protocol's default-graph-uri or named-graph-uri
parameters:
http://openanzo.org/namedGraphs/reserved/namedGraphs/ALL
If your queries seem to be returning no results when you think they
should, then that might be the issue.
