    • Lessons LearnedOAC Phase II Review Meeting, JUly 26th, Chicago
    • Lessons Learned • Implementing RDF in Ruby (on Rails) • another server-side serializer • needed to register mime-type mappings for conneg • implemented to_rdf() for maphub modelOAC Phase II Review Meeting, JUly 26th, Chicago
    • Lessons Learned • OA Model Complexity • our use cases are relatively simple • the resulting OA serializations are pretty complex • demanding for developers ( = the people who will read / use the spec)OAC Phase II Review Meeting, JUly 26th, Chicago
