Make sure your URIs are part of the OntoWiki installation namespace

If your OntoWiki is under http://example.org/OntoWiki/ you shoud create a Knowledge Base http://example.org/OntoWiki/YourData/ or similar and create your resources in it like http://example.org/OntoWiki/YourData/Person/Norm .

Login as an Admin, search for Users in the System Config and and add your Knowledge Base to the property `readable model` for the Anonymous User.

It is also possible to restrict the access to your Linked data but this means that linked data clients need to authenticate with HTTP auth.
