Congratulations on a great first draft for the Requirements for a Web Ontology Language. Your statement of requirements is extremely comprehensive. One of the few areas in which an improvement is to be desired relates to: Ontology metadata It must be possible to provide meta-data for each ontology, such as author, publish-date, etc. The language should provide a standard set of common metadata properties. These properties may or may not be borrowed from the Dublin Core element set. It should be possible to identify the author and update date of an individual term within an ontology. Ontologies are rarely the work of a single person, and rarely created at a single point in time. You need to be able to identify which changes have been applied in each version. This can only be done if individual terms carry enough information as to their currency. I would also suggest you review the suggestion, under View Mechanism, that: "This is particularly useful in developing multicultural versions of an ontology. Note that this requirement may be satisfied by having multiple ontologies and using an ontology mapping mechanism." This is certainly not the most efficient way to identify relationships between different sets of terms in multilingual ontologies. There are severe problems with ensuring the update of parallel ontologies when they are maintained separately.
