Abstract: An example computer-implemented method to download and organize attachments from messages includes downloading a message attachment and related message metadata from a messaging database such as an email attachment. The example computer-implemented method can then include indexing the message attachment using the message metadata. The example method can then include identifying a year of receipt and a sender of the message and present the attachment in a collection organized by year of receipt and sender.

Abstract: A method, system, and computer program product for of processing database queries using the resource description framework (RDF) language through a gateway service. The method commences by receiving a database query (e.g., an SQL query) from an application, the query being in a first query language format, then converting the query into a SPARQL query format and submitting the converted query to a SPARQL endpoint. The SPARQL endpoint processes the SPARQL query (e.g., by accessing an RDF repository), and sends back the query results. A gateway service (e.g., a SPARQL gateway) then receives the SPARQL query results from the SPARQL endpoint and transforms the SPARQL query results into a format corresponding to the first query language format so the initiating application can process it natively. Several performance features are disclosed, including a method for achieving a quality of service level by concurrently submitting multiple SPARQL queries with different LIMIT clauses.
