Constantinople, Bardill
2004, type 6601.c. Ca 510/11

6.  The typical kinds of ties between two sites, here imagined 40 km distant from each other, and four clay sources. The relationships are based on co-appearance of names in different
stamps, use of the same clay sources, and so on. The result is multiple overlapping and intersecting networks!

16. to import-attributes
;; This opens the file, so we can use it.
file-open "places-attributes-v3.txt“
;; Read in all the data in the file
;; data on the line is in this order:
;; node-id attribute1 attribute2
while [not file-at-end?]

;; this reads a single line into a three-item list

set color item 2 items
]

end

17. ;; This procedure reads in a file that contains all the links
;; The file is simply 3 columns separated by spaces. In this
;; example, the links are directed. The first column contains
;; the node-id of the node originating the link. The second
;; column the node-id of the node on the other end of the link.
;; The third column is the strength of the link.
to import-links ‘Links’ & ‘Attributes’ files
;; This opens the file, so we can use it.
file-open "place-to-place-links-v3.txt“ can be created by
copying and pasting the

19. Model is a mashup of ‘Network Import’ & ‘Virus transmission on a network’, with the
idea of modifying the virus to simulate ideas about social contagion (eventually).
