The problem with trees Many systems are organized hierarchically. The CERNDOC documentation system is an example, as is the Unix file system, and the VMS/HELP system. A tree has the practical advantage of giving every node a unique name. However, it does not allow the system to model the real world. For example, in a hierarchical HELP system such as VMS/HELP, one often gets to a lead on a tree such as: HELP COMPILER SOURCE_FORMAT PRAGMAS DEFAULTS only to find a reference to another leaf: Please see HELP COMPILER COMMAND OPTIONS DEFAULTS PRAGMAS and it is necessary to leave the system and re-enter it. What was needed was a link from one node to another, because in this case the information was not naturally organized into a tree.

The Pleasure of Observing An Essay from Field Notes on Science and Nature by George B. Schaller AbbreviationBeyond dry factsA study should persistPrecious intangible valuesIndependent fragments of existence+1 More
Abbreviation I generally do not like to abbreviate behavioral notes. An important detail may be ignored or considered irrelevant and discarded because it lacks a discrete category on the list. It is often an anecdotal event that offers special insight.
Beyond dry facts If one has a personal knowledge of the individual animals being studied, observations in field notes cease to be impersonal, and an observer’s empathy can lead beyond dry facts to better intuition and insight.
A study should persist Since we cannot interview the subject, we can only infer the past from the present. Ideally, a study should persist for at least the life span of an animal. research
