  <description><![CDATA[The maturation of semantic web standards and associated web-based data representations like schema.org have made RDF a popular model for representing graph data and semi-structured knowledge. However, most existing SPARQL endpoint supports simple access control mechanism preventing its use for many applications. To protect the data stored in RDF stores, we describe a framework to support attribute-based fine grained access control and explore its feasibility.

  <description><![CDATA[Resource Description Format (RDF) stores have formed an
essential part of many semantic web applications. Current RDF
store systems have primarily focused on efficiently storing
and querying large numbers of triples. Little attention has
been given to how triples would be updated and maintained or
how access to store can be controlled.

In RDF stores addition and deletion of facts are not atomic,

  <description><![CDATA[RAP looks at solving the problem of defining and implementing Access Control for a RDF store. The work involves expressing these controls using and implement a prototype.

The basic RAP framework will allow an agent (person or program) to perform various actions inserting, deleting, searching on a RDF store and the policy is used to decide if the action is permitted or prohibited.

Some of the aspects to be dogged are, how to represent the policies (REI, N3, Prolog  ... etc), what level o...]]></description>

205,000 is the number of visits to the Ebiquity web site.  Our monthly page visits increased five fold over the year and we currently receive about 25,000 visits a month.

  <description><![CDATA[Specialized RDF stores are essential parts of many Semantic Web applications. Current RDF stores have focused primarily on efficiently storing and querying large volumes of data, with little attention to other features common to many database systems, including how information is updated and maintained and how data access is controlled. The problem is complicated because adding or deleting a simple fact (i.e., an RDF triple) is not atomic, since it can trigger reasoning that adds or deletes d...]]></description>
