Stellaris Description

Enabling flexible metadata management for the Grid Stellaris is a free and open source metadata management service developed within the AstroGrid-D project. Our focus is to provide a flexible way to store and query metadata relevant for e-science and grid-computing. This can range from resource description of grid resources (compute clusters, robotic telescopes, etc.) to application specific job metadata or dataset annotations. Stellaris uses common web-standards such as RDF to describe metadata and the accompanying query language SPARQL. Here are some key features of "Stellaris": · A simple but powerful management interface for RDF-graphs · Different backends for indexing through the use of RDFLib and Virtuoso · Authentication using X.509-certificate verification · Group-based authorization system · SPARQL-protocol implementation with both XML/JSON result formats · Graph lifetime management · Stand-alone deployment or embeddable in Apache using WSGI Requirements: · Python What's New in This Release: · Minor fix to update setup.py with the correct versions of dependencies
