Links between the nodes are structured with explicit definitional roles, types of inheritance, defaults, and various data formats. This paper presents the general ideas of the Unit Package and compares it with other current knowledge representation languages. The Unit Package was created for a hierarchical planning application, and is now in use by several AI projects.","doi":null,"url":"https://ijcai.org/proceedings/1979/185","pdf":"https://ijcai.org/proceedings/1979/0185.pdf","markdown":"https://ijcai.org/proceedings/1979/185.md","bibtex":"https://ijcai.org/proceedings/1979/bibtex/185","volume":{"slug":"1979","title":"Proceedings of the Sixth International Joint Conference on Artificial Intelligence","short_title":"IJCAI 1979","url":"https://ijcai.org/proceedings/1979/","year":1979,"location":"Tokyo, Japan","dates":"August 20-23, 1979","editors":"Bruce G.
