| + Sparrow aims at combining algorithms and techniques from logic-based knowledge representation and databases into a single, open-source toolkit. Sparrow will also include new approaches to handle semantic information in scientific applications. |
| + |
| + Sparrow will provide: |
| + |
| + * lighweight machine AND human readable versions of common knowledge representation languages such as first-order logic, description logic (DL) fragments, and RDF, as well as "special purpose languages," e.g., for semantic data and service registration. |
| + * conversion routines to translate between languages (e.g., OWL to Sparrow-DL and vice versa) |
| + * formula manipulation and reasoning algorithms, e.g., for concept subsumption, classification, chasing parameter dependencies, reasoning with units and semantic types |
| + * query rewriting using semantic contraints for distributed mediation, e.g., containment checking, planning with limited capabilities and GAV/LAV views |
| + * ontology-based data transformation |
| + * specialized tools for viewing and manipulating knowledge bases (e.g., conceptual models and ontologies). |
| + |
| + Discussion of Sparrow occurs on the seek-kr-sms@ecoinformatics.org [mailing list|Forums]. |
