After thinking about last week's meeting, I collected some observations from
the presentations and some perceived needs. I share these in the hope of
provoking some reactions from you, either of agreement, disagreement,
elaboration or augmentation. (01)
These have also been entered on the Track 4 (Applications) synthesis page as
well as on the Track 4 Community Input page, where I hope you will add your
thoughts. (02)
I will continue to collect nuggets as I encounter them. (03)

* Observations / Lessons learned:
** UML to OWL is a common requirement for legacy systems
*** Need better tools to help interpret legacy systems, transform into
semantic systems.
*** Starting from scratch is rare. (06)
** Ontology patterns are very helpful, and encourage model reuse
** Look for the 80-20 rule of semantic development
** Semantic techniques work best when not compromised by implementation
tradeoffs
** Semantic methods are faster to implement and easier to maintain
** Semantic approaches particularly suited to systems with many complex
constraints, rules, laws, with frequent changes (07)
* Needs:
** Need better standards for common elements:
*** Datatypes (Are xsd types enough? I think not)
*** Ontology patterns (e.g. whole/part patterns)
*** Collect ontological primitives from observation data (08)
** Need repositories (When is OOR going to be ready for production use?)
*** Repositories of ontological patterns could be more useful than
repositories of ontologies (09)
** Need industrial strength semantic services resident in the cloud
** Need better visualization tools and approaches (010)
