We define a single tab-delimited approach for data files of network data. The first file contains node information and the second file contains link information.
Node Data File
In this example, the first tab-delimited file has the set of nodes: a person has an ID and a NAME. The node attributes are HEIGHT (in inches), SEX (M or F), WEIGHT (in pounds), and BIRTH (date).
ID NAME HEIGHT SEX WEIGHT BIRTH INTEGER STRING INTEGER STRING DOUBLE DATE 13 Ann 65 F 128.5 1996-02-17 15 Bob 66 M 194.6 1993-12-06 51 Charles 69 M 174.1 1996-02-17 58 Dan 72 M 194.7 1991-09-13 77 Edwina 59 F 102.2 1994-12-29
First row items are not reserved words, but the first column is the key. Data types are reserved words: INTEGER, STRING, DOUBLE, DATE
Link Data File
The second tab-delimited file has the set of links: a person (ID1) has a perceived friendship with another person (ID2) (one-directional from ID1 to ID2), in which the perceived length of the friendship is in days (LENGTH) and the perceived intensity (DEPTH) is from 0.0 to 10.0.
ID1 ID2 LENGTH DEPTH INTEGER INTEGER INTEGER DOUBLE 13 15 34 4.3 13 58 51 5.6 13 77 17 2.2 15 13 44 4.9 51 58 36 4.6 51 77 55 6.5 77 51 32 5.4 77 15 41 6.6
First row items are not reserved words, but the first two columns are the source and destination for the link. Data types are reserved words: INTEGER, STRING, DOUBLE, DATE
