2. DAML Excitement at Cycorp
Promoting DAML ontology interoperability through Cyc, as a reference ontology.
Cyc now imports and exports DAML, paraphrases and reasons about it.
Cyc lexical tools assist the mapping of imported DAML ontologies into Cyc.
Both UDDI categorization schemes imported as DAML into Cyc:
UNSPSC (via KSL) and NAICS
Cycorp is featuring DAML in it’s upcoming release of OpenCyc (this fall).

3. DAML Challenges at Cycorp
How to automate mapping and translation of DAML ontologies.
How to get the user community to help map numerous DAML terms -- interest growing at OpenCyc.
Importation of large DAML schema is daunting but underway, WordNet, OpenDirectory, UNSPSC, NAICS
Provide an inference engine for the Semantic Web - subsumption, classification, constraints, well-formed statement validation, diagnostics, justifications.
What web services interface? SOAP likely.

7. UNSPC/NAICS Mapping
Universal Standard Products and Services Classification, North American Industrial Classification System
Both business taxonomies are monohierarchies, entities should have one code assigned for them.
Cyc: #$MonohierarchyClassificationSystem implies that each collection is #$partitionedInto its narrower terms.
Mapping is targeted at facets of the reference Cyc terms via functional composition.

8. Mapping to Semantic Facets
Hardwood International is an online store, selling mainly lumber but offering hardware as well, but NAICS is a monohierarchy.
