Center node: "semantic modeling with foundries"
  Abstract: We analyze challenges for the development of the Human Activity and Infrastructure Foundry, which we had previously proposed. For example, we consider two Korean ceramic water droppers used to mix ink for calligraphy. We explore a rich semantic modeling approach to describe them, how they were produced, and the reasons for their differing aesthetic. This modeling approach is closely related to object-oriented modeling, and we describe some of the implications of that for the design of Human Activities and Infrastructures Foundry (HAIF) ontologies. Ultimately, we conclude that while object-orientation is an important foundation, other paradigms should also be supported for the description of complex scenarios.

Connected through hyperedge HE-1 (induced by source paper "definitions and semantic simulations based on object oriented analysis and modeling"):
  with members:
    - "issues for using semantic modeling to represent mechanisms"
    - "xfo toward programming rich semantic models"
    - "rich semantic models and knowledgebases for highly structured scientific communication"
