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 brilliance of notion
This, I think, is the brilliance of Notion, and what makes it one of the best examples of “fidelity to digital information” that I’ve come across. The structure of the app reflects the structure of the web itself: digital content is purposefully formatted, like semantic HTML elements, and exists in a hierarchical structure (directories on the web, nested pages in Notion), yet can be linked and referenced to create a complex network of information. And pages in Notion reveal the structure of the information: when nesting a page within a page, the child page always displays on the parent page. There’s no way to create a child page that doesn’t display on a parent page, no way to obscure the structure of the information. The semantic structure of Notion reflects the semantic structure of the web itself.
Separation and connection in all things
Truchet's approach was more topological than geometric, and the qualitative aspects of pattern take priority over the metric ones. His principles provide a kind of metaphor for the hierarchy of separation and connection in all things.
Linking Researchers Across Generations
Future value
In the field, there is a continuous flow of information that consists of daily observations, insights, and data. How can I capture these data and thoughts in notes, maps, and images so that they will be of value both to me and to future generations of scientists?
Time capsules
In recording fieldwork I was creating my own time capsules.
Tools of the digital age
The myriad tools of the digital age that provide quick ways to capture words, images, and data have added to the perception that handwritten field notebooks are passé. As someone who routinely encounters objects that can speak to us over millions of years, I may have a bias towards things that have stood the test of time. That said, it is clear that there is still much to recommend preserving records and information in traditional paper field notes.
Over the course of my career, I have developed a habitual field note protocol in which a paper notebook is used both to record information and to integrate records made on standardized data sheets, in computer files, and in photographs.
Five basic rules
Five basic rules:
(1) Record your work as notes to your future self and colleagues.
Write notes so that someone fifty years from now (or more) will understand and be able to use the factual information you collected, perhaps for purposes quite different from the original reasons.
Clearly separate facts from interpretations so these are not confusing to a future reader.
(2) Establish a clear and consistent notebook format and process.
I always include the data, place, main activities or events, weather conditions, and other people involves. The day, month, and year is the most important link between that particular point in time and other people’s records, separate data sheets that I filled out myself, photos, and most important, collected specimens.
Documenting collecting strategies and protocols receives special attention. In the moment, these may seem like common knowledge for the field team, so sometimes no one bothers to write them out.
(3) Don’t lose your field records!
(4) Pack a camera, create a visual record.
No matter how many words you write to describe a fossil locality, you can’t beat an actual photo, taken on the spot, annotated in pen, and pasted into your notebook.
There is no substitute for a photograph you actually mark in “real time” in the field as the best way to preserve a lasting, accurate record for yourself, or for someone who has never seen the site or object in question.
(5) Learning through sketches and diagrams.
Photographs are great, but drawn what you see is a more powerful way to learn about spatial patterns and relationships.
Even if you are not an expert at drawing, you can make sketches that are much more informative than words would be.
Always include a scale, an orientation, and labels in your diagrams.

Informally I refer to these as “bonewalks.”
