SPARQL-DL: SPARQL Query for OWL-DL

There are many query languages (QLs) that can be used to query RDF and OWL ontologies but neither type is satisfactory for querying OWL-DL ontologies. RDF-based QLs (RDQL, SeRQL, SPARQL) are harder to give a semantics w.r.t. OWL-DL and are more powerful than what OWL-DL reasoners can provide. DL-based QLs (DIG ask queries, nRQL) have clear semantics but are not powerful enough in the general ca...

Extending the 5S Digital Library (DL) Framework: From a Minimal DL towards a DL Reference Model

In this paper, we describe ongoing research in three DL projects that build upon a common foundation – the 5S DL framework. In each project, we extend the 5S framework to provide specifications for a particular type of DL service and/or system – finally, moving towards a DL reference model. In the first project, we are working on formalizing content-based image retrieval services in a DL. In th...

SYNTHESIS AND DETERMINATION OF THE LIPOTROPIC ACTIVITY OF THE BETAINE HYDROCHLORIDES OF dl-SERINE, GTHREONINE, AND dl-ALLOTHREONINE*

This paper reports the synthesis of the betaine hydrochlorides of serine, threonine, and allothreonine and a study of the action of these substances on the lipid content of the livers of rats fed a high fat, low protein diet. This work was undertaken for two purposes. Best and Huntsman (1) found that choline prevented the development of fatty livers in rats fed a high fat diet and that betaine ...
