Entry by SteveRay, 2/21/2012 {nid 35D3} * Observations / Lessons learned: {nid 35D4} ** UML to OWL is a common requirement for legacy systems {nid 35D5} *** Need better tools to help interpret legacy systems, transform into semantic systems. {nid 35D6} *** Starting from scratch is rare. {nid 35D7} ** Ontology patterns are very helpful, and encourage model reuse {nid 35D8} ** Look for the 80-20 rule of semantic development {nid 35D9} ** Semantic techniques work best when not compromised by implementation tradeoffs {nid 35DA} ** Semantic methods are faster to implement and easier to maintain {nid 35DB} ** {nid 35DC} ** Semantic approaches particularly suited to systems with many complex constraints, rules, laws, with frequent changes {nid 35DD} * Needs: {nid 35DE} ** Need better standards for common elements: {nid 35DF} *** Datatypes (Are xsd types enough? I think not) {nid 35DG} *** Ontology patterns (e.g. whole/part patterns) {nid 35DH} *** Collect ontological primitives from observation data {nid 35DI} ** Need repositories (When is OOR going to be ready for production use?) {nid 35DJ} *** Repositories of ontological patterns could be more useful than repositories of ontologies {nid 35DK} ** Need industrial strength semantic services resident in the cloud {nid 35DL} ** Need better visualization tools and approaches {nid 35DM} ---- |
