The record

Purpose: Mulgara stores metadata and creates relationships between it in a semantic store.
RDF and queries: Its databases store metadata as RDF subject-predicate-object statements and can be queried with SPARQL or TQL.
Features: The project lists native RDF support, multiple databases per server, full-text search, datatype support, and a small footprint among its general features.
Scale: Listed performance features include large storage capacity, low memory requirements, on-disk joins, streamed query results, and support for multi-processor systems.
Reliability: The overview lists full transaction support, clustering, store-level fail-over, and permanent integrity.
Connectivity: The overview lists Sesame SAIL API, JRDF, SOAP, HTTP, and a Software Developers Kit as connectivity options.
Administration: The project describes near-zero administration and web-based configuration and monitoring tools.
Web services: A default standalone server configuration provides a SPARQL HTTP service, TQL HTTP service, web services, user interface, and tutorial.
